Botanising the Scarp Edge

 We were on the hunt for two Liparis species. To get there, we gained access through the farm, passing dams that were completely full to the brim. Out on the water, Spur-winged geese and Yellow-billed ducks paddled about. The Zantedeschia aethiopica were flowering in mass around the dam. As we reached the boundary, Alf and Uschi jumped out to open the gate into the reserve, with Gail paying for their service in pennies, salt, and cowrie shells!

Towering sandstone cliffs

We drove right up to the scarp forest along the edge of the sandstone cliffs. We had our cup of coffee and a quick catch up. It was humid and hot, the sky was a clear blue canvas. The vibrant mauve-pink stems of a Ledebouria asperifolius stood out against the wisps of grass. The smooth, fleshy flower stalk transitioning into a dense, cylindrical cluster of deep pinkish-purple buds. It belongs to the family Asparagaceae.

Ledebouria asperifolius

As we wandered, eyes scanning, we chatted away. A Syzygium cordatum (umdoni) twisted, pulling against some unseen force moulding it into something tough and beautiful. Multitudes of long, filamentous stamens sat at the ends of the branches, the tiny, inconspicuous petals having dropped off very early, giving the entire cluster its signature soft, brush-like, cream-coloured appearance. It was fascinating to see how the developing peduncles and pedicels mimic the leaf arrangement, perfectly reflecting the opposite and decussate geometric blueprint of this genus, which belongs to the family Myrtaceae.

Syzygium cordatum

Between some boulders in the shade of a tree we looked at Pelargonium capitatum (rose-scented pelargonium). It is a member of the family Geraniaceae. This sprawling shrub has soft, crinkly leaves covered in tiny glandular hairs, which store the rich essential oils that release their sweet fragrance at the slightest touch—and touch it we did! Even the seeds are uniquely adapted for wind and soil security; each elliptic seed is attached to a feathered, tail-like structure that coils into a tight spiral, acting like a mechanical drill to screw the seed safely down into the ground. Locally, the leaves are traditionally used as a soothing skin emollient to treat rashes, dry calluses, and cracked heels, while infusions made from the leaves have historically been used in folk medicine to treat bladder and stomach ailments. This definitely sounds like the perfect friend for a botanist out in the field!

Pelargonium capitatum

The very next plant drew attention but not because it is particularly attractive, but because it looked oddly out of place. It was Solanum retroflexum (nastergal), which of course was totally in the right place. Belonging to the family Solanaceae, its delicate, star-shaped white flowers center around bright yellow anther cones. It looked quite modest amidst the surrounding flora, yet its presence reminded us of the sheer diversity tucked into every layer of the reserve.  The berries are edible, but only when fully ripe; otherwise, when green, they are poisonous. Once they achieve their characteristic dark, matte-purple finish, they are safely hand-harvested to make the famous, deeply sweet traditional nastergal konfyt.

Solanum retroflexum

Clinging effortlessly to the stalk of Pteridium aquilinum subsp. aquilinum (bracken) was a Hyperolius marmoratus (painted reed frog). Fully aware of our presence, it remained perfectly still. This tiny climber belongs to the family Hyperoliidae. To avoid detection by predators during the heat of the day, individuals typically tuck their legs tightly beneath their bodies and remain completely motionless on vegetation, relying on their highly variable, marbled patterns as an absolute mastery of camouflage—but not from the gaze of Dorothy!

Hyperolius marmoratus

Dalbergia obovata (climbing flat-bean) is flowering vigorously all over the reserve at the moment and is quite attractive when covered in small, butter-yellow flowers. Part of the family Fabaceae, this native species is a vital nitrogen-fixer for the reserve’s soils. Growing right alongside it was Lauridia tetragona (climbing saffron) with its fresh new red leaves. A member of the family Celastraceae, this multi-stemmed scrambler is easily recognised by its characteristically square, four-angled stems. Its beautiful foliage serves as the vital larval host plant for the Rainforest Acraea butterfly (Acraea boopis), a species heavily dependent on pristine forest margins.

As we moved along the damp forest margins, a beautiful Psoralea arborea (mountain fountain-bush) stood before us. Belonging to the family Fabaceae, this elegant, tree-like shrub produces fine, needle-like green foliage and clusters of blue and white pea-shaped flowers. It naturally prefers these moist, waterlogged habitats along stream banks and forest borders. Further along we passed by a Faurea macnaughtonii (Terblans beech). The red stems seemed to bleed into the central veins and leaves, giving them a warm glow. Belonging to the family Proteaceae, this rare tree is widely celebrated for these elegant, lance-shaped leaves with characteristically wavy margins that beautifully catch the filtered light along the forest margins. It is classified as Rare because it naturally occurs in small, isolated, and highly fragmented pockets across the country.

The day had just gotten hotter and the humidity was climbing; we were eager to get into the forest. Anne and Alf were already in the forest when Anne shouted that she had found Liparis bowkeri (Bowker’s liparis). We hurried down to see them nestled beautifully in the leaf litter! Their thin, light-green leaves fanned out elegantly with strongly ribbed, longitudinal veins, while upright, unopened flower scapes rose straight from the center of the plants. These pseudobulbs do not grow buried under the soil like normal roots; instead, they sit right above the ground. They belong to the family Orchidaceae. Reaching out to hold onto a tree I found a Rhoicissus species, its trifoliate Leaves held a interesting shape we could not recognise. It belongs to the family Vitaceae, it clambered gracefully along the forest floors, and twirled up nearby trees. The forest floor was covered in damp leaf litter and every mossy rock was slick as glass. Each step had to be carefully planned, but a botanist easily gets distracted by a plant. Sure enough, a misstep sent me skidding right off the end of a boulder. By some miracle, I landed squarely on my feet like a cat, heart pounding.

Sprayed across the forest floor the little white stars of Chlorophytum comosum (hen-and-chickens / spider plant) is always an enchanting sight. It belongs to the family Asphodelaceae. We were quickly pulled away when Anne found the second Liparis species: Liparis remota (forest fly orchid). Belonging to the family Orchidaceae, this miniature geophyte is easily distinguished from its cousin on the forest floor. While Liparis bowkeri carries heavily ribbed, pleated leaves, Liparis remota features 3 prominent main veins on a distinctly flatter, smoother leaf surface that spreads horizontally over the litter, with its pseudobulbs nestled in the substrate and connected by an extended, creeping rhizome that sends up new vegetative growths a few centimeters apart.

Anne was being extremely brave moving between two large boulders near the edge to get a look at a fern that always gets us excited because it is so unique. In fact, it is a firmoss and not a fern at all. It was first named in 1782 as the clubmoss Lycopodium gnidioides, but as botanists realized its unique structure was that of a true firmoss, it was moved to Huperzia gnidioides in 1874. It remains widely known by this name in South Africa today. However, modern DNA studies have shown that it belongs to a distinct tropical lineage, leading global databases to transition it to Phlegmariurus gnidioides in 2013. This simply reflects an ongoing conversation among taxonomists as modern science evolves. Belonging to the family Lycopodiaceae, it is a spectacular lycophyte indigenous to our moist South African forests, including right here in the misty depths of the Umtamvuna Nature Reserve. On the side of the same boulder was Vittaria isoetifolia (bootlace fern). Remarkably, this is the only documented species of this genus found natively in South Africa. Belonging to the family Pteridaceae, this unique lithophytic species produces numerous tightly clustered, dark green fronds that hang straight down like long, slender shoestrings. It is perfectly adapted to these shaded rock faces, bearing linear sori tucked away in deep, protective grooves along the very edges of the undersides of the leaves.

Out in the grassland, we could still hear the Red-chested Cuckoo calling Piet-my-vrou, Piet-my-vrou—a truly South African soundtrack to a Pondoland C.R.E.W. field trip. The heat out in the open was a sharp contrast to the cool forest canopy. The bright yellow pea flowers of Aspalathus chortophila (impishimpishi) contrasts beautifully against its small, needle-like green leaflets. Belonging to the family Fabaceae, this hardy, low-growing shrublet is perfectly adapted to the dry, sun-drenched landscape. Dorothy and I sat quietly on a rock—well, I say “quietly,” but anyone who knows us knows that Dorothy and I will never be quiet!

Aspalathus chortophila

We chatted away about what Dorothy had seen. While we were down exploring the cool, shaded depths of the scarp forest, Dorothy was busy conducting her own botanical treasure hunt. She noted Muraltia lancifolia (umahesaka-onsundu), a hardy South African endemic belonging to the family Polygalaceae. The traditional isiZulu name beautifully captures its appearance, contextually translating to “rough brown sack” to describe its tough, rigid, and brownish ericoid growth habit out on the plains. Right alongside it was Apodytes abbottii (Pondo white pear), a range-restricted and Near Threatened tree of the family Metteniusaceae. This rocky survivor is a master at squeezing its roots into solid sandstone fissures where larger trees could never survive.

Tucked closer to the edges, she also spotted Tricalysia capensis (forest jackal-coffee), a member of the family Rubiaceae, and the soft, semi-succulent foliage of Plectranthus saccatus (stoep jacaranda), which belongs to the family Lamiaceae. This beautiful mint relative carries its large lilac blooms in specialized sprays that face strictly to one side of the stem, while its leaves feature tiny, translucent gland dots that look like miniature windows when held up to the sun.

Dorothy’s sharp eyes also picked out a diverse array of grassland herbs and pea-flowered perennials soaking up the intense summer heat. She recorded Eriosema salignum (umfuthu), a resilient member of the family Fabaceae, alongside the tough, leathery-leaved Gnidia coriacea belonging to the family Thymelaeaceae. Adding to the grassland’s vibrant variety were the parasitic blooms of Striga bilabiata (heather mimic witchweed), part of the family Orobanchaceae. True to its name, this root hemiparasite perfectly mimics surrounding heaths above ground while its hidden underground roots tap into nearby grasses to steal water and nutrients. Finally, she rounded out her list with Anemone afra (African windflower) in the family Ranunculaceae, and a brilliant splash of color from Freesia laxa (false freesia), belonging to the family Iridaceae. It is safe to say her time on top was just as botanically rewarding as our orchid hunt below!

Another forest edge shrub Pseudoscolopia polyantha (false red pear / sandstone red-stem) had finished flowering, the fruits capsules were starting to bulge out of the calyces. Belonging to the family Salicaceae, this remarkable perennial tree is beautifully adapted to these rugged sandstone outcrops and forest margins, showing off its characteristic grey-brown flaking bark and striking red young stems. Its opposite, simple, and leathery leaves feature bluntly toothed margins. We were fortunate enough to capture a close-up of its small, green developing fruit capsules forming in compact heads at the branch tips, perfectly showcasing how the young capsules taper and expand from the center of their persistent floral structures.

Pseudoscolopia polyantha

Going back towards the Jimnys and along the edge, we found Brachystelma australe. We had been scouring the rocks for weeks waiting to see these little open, star-shaped maroon flowers. Belonging to the family Apocynaceae, this specialized South African endemic produces long, low-growing, decumbent stems from a small underground caudex that stores moisture against the harsh, sun-drenched conditions of the open reserve. True to its family lineage, the tiny flowers emit a faint, distinct organic scent that mimics decaying material. This pungent mimicry is a clever evolutionary strategy designed to lure in tiny flies and beetles; as the deceived insects crawl inside the star-shaped blooms, their mouthparts or legs catch onto microscopic pollinia traps, ensuring the pollen gets hitchhiked directly to the next hidden plant. Small succulent Delosperma subpetiolatum (grassveld trailing sheepfig) trailed across the sandstone. Belonging to the family Aizoaceae, this Vulnerable South African endemic is a true specialist of these rocky sandstone sheets.

We then started to climb down into one of the most precious scarp forests in Umtamvuna, sitting between the grassland on a small shelf before the sandstone cliffs fall down, down into the gorge. Dallying behind, I noticed some Phytolacca octandra (forest inkberry). Belonging to the family Phytolaccaceae, this highly invasive Category 1b weed is a troublesome alien invader that thrives on forest margins. It produces spikes of small greenish flowers that mature into dark, glossy, stain-producing berries. Its presence serves as a constant reminder of why monitoring these fragile, pristine margins is so critical. I pulled it out and hung it out to dry before following the rest into the forest.

Phytolacca octandra

Hanging from a Podocarpus species (yellowwood) in an untidy mess, we found Tridactyle bicaudata subsp. bicaudata (iphamba). Belonging to the family Orchidaceae, this robust epiphyte forms large, coarse hanging clumps securely anchored to the host tree’s bark. To stay firmly suspended, it relies on a network of thick grey aerial roots wrapped in a spongy cell layer called a velamen. Where these roots make contact with the tree, they flatten completely like strips of tape to grip the flaking bark. Its elongated woody stems carry numerous leathery leaves arranged in two opposite rows, which grow thinner and flatter in the shade. Small, buff-yellow star-like flowers that erupt along the mature stems.

Tridactyle bicaudata subsp. bicaudata

The next flower we saw was the beautiful anomaly Hypoxis membranacea (small white star flower). While it belongs to the family Hypoxidaceae, famous for yellow flowers, this delicate geophyte produces fragile, pure white, six-parted flowers centered with vivid orange-yellow anthers. The pale green, membranous leaves are covered in distinct, fine spreading hairs, allowing it to hide effortlessly in the damp leaf litter of the forest floor where it keeps a low profile, but not this day you could not miss it. Stepping into the forest is otherworldly, and each step you take is carefully placed so as not to leave even footprints.

Hypoxis membranacea

Our next discovery was the exquisite Bulbophyllum scaberulum var. scaberulum. Belonging to the family Orchidaceae, this creeping epiphyte produces distinct ovoid or pear-shaped yellow pseudobulbs that crawl along the substrate via a tough, woody rhizome. We photographed it growing directly on the sandstone rocks. Rising straight from the base of these bulbs is a remarkable, erect inflorescence featuring a heavily thickened, flattened, and swollen rachis. The fleshy, deep purple flowers are set alternately in two strict rows along either side of this flattened blade, making it one of the most uniquely structured orchids in the entire reserve. It is truly remarkable.

Bulbophyllum scaberulum var. scaberulum

I had gone as far as I could and so turned back, you’ll be amazed what you see the second time around in the shadows or the crook of a tree. Coming back there at the foot of a tree was Liparis bowkeri (Bowker’s liparis) in flower. Its small, translucent green flowers lack true nectar spurs; instead, they create a clever illusion. Their lateral petals are modified into narrow, thread-like structures that protrude directly below the sepals, giving the impression of two distinct spurs.

Anne and I passed each other, Anne pointing to Clutia abyssinica var. nov. Belonging to the family Peraceae, this species has large alternate leaves that are covered in velvety hairs, small almost translucent white flowers grew from the leaf axils. It is really quite different from others Clutia species. In the understory, I was so excited to see Syzygium gerrardii (forest waterberry / isiduli). Belonging to the family Myrtaceae, having seen Syzygium cordatum earlier made this find even better. While both species share this “powder-puff” look, Syzygium gerrardii carries much smaller, more delicate, and highly fragrant clusters. This impressive forest specialist features glossy, lance-shaped dark green leaves that narrow into distinct, drawn-out tips, bearing these compact clusters of tiny white filamentous stamens at the branch tips to release a sweet scent that drifts softly through the shaded understory. Earlier we had seen the fresh growth, and now Anne pointed out the small, inconspicuous flowers of Lauridia tetragona.

We sat in the cool forest, listening to the Red-chested Cuckoo still lamenting Piet-my-vrou while we ate our lunch. With happy hearts, we packed away our lunch containers, then began to leave the forest. We leave a small part of ourselves in that forest, perhaps to let it root there until our return. While we made our way out of the forest, we noticed small four petaled white flowers with a whisper of pink. On closer inspection, we realized it was Ekebergia pterophylla (rotsessenhout). Belonging to the family Meliaceae, this evergreen species features compound, leathery leaves with a distinctively winged central stalk, making it a highly characteristic specialist along these rocky forest margins.

Ekebergia pterophylla

Back out in the open we meandered along the edge, admiring stunning lichens clinging to the exposed tree branches. A Protorhus longifolia was full of large bunches of plump plum-coloured drupes sitting against shiny dark green leaves. What a show. Out on the sandstone pavement, Delosperma vinaceum (wine-colored ice plant) sat almost hidden between the grass, with its bright magenta flowers fully open to the sun. Belonging to the family Aizoaceae, this tough succulent forms compact, ground-hugging mats directly over the bare sandstone sheets. Its fleshy, cylindrical green leaves carry a subtle frosted shimmer that reflects the intense heat, providing a striking contrast against the brilliant flushes of its daisy-like flowers. We looked over at the waterfall, expecting to see water thundering down to the gorge far below after all rain, but there was only the smallest stream.

Below us on the next ledge, we noticed familiar star-shaped flowers on zigzag stems, but in crisp white: Hesperantha hygrophila. They belong to the family Iridaceae, this dainty cormous geophyte is a specialised water-lover that grows on these damp rocky seeps. In contrast to these gorgeous pristine white flowers a little further there were hundreds of Bidens pilosa (Black Jack) seedlings. We stopped to pull them out preventing thousands of seeds from choking out the next generation of rare grassland plants.

Slowly we made our way back to the Jimnys. There were so many Crassula vaginata growing in the grass in an array of yellow and copper hues. It looked like a scene that Vincent van Gogh might have painted. At the Jimnys, Gail brought out a slab of dark chocolate and suddenly, by a miracle, we were all for a moment quiet—but a very brief moment. The day had come to an end, another successful day botanising. We were hot and a little grubby, but that’s a Thursday for you.

Hold onto your Breeches we're Botanising

 We had chosen to botanise in the Western Heights. Dorothy was back from visiting family, but Maggie was home taking delivery of a very special chair—it would need to be to miss a Thursday! A quick stop at Beacon Hill to jump into the Jimnys, and we were on our way. There was a lot of chatter, as there was plenty to catch up on.

Apodytes abbottii

The road to the Western Heights is bumpy, full of rocks, and this week, full of water and mud after the wonderful rain we had received. The track often changes course when it becomes unmanageable, so you had best hold onto your breeches.The gate to the reserve was off its hinges; it had been for a while, we can’t remember when last we had to stop to open and close it. The strands of barbed wire marking the boundary of the reserve are rusty and decayed, the fence having long stopped serving its purpose.

Western Hieghts

The grassland looked healthy, except for the cattle paths that cut through the veld. We were looking for short grass to make the walking easier, so we drove to the burnt section where the new growth was green and fresh. The heavy footprint of the grazing cattle was unmistakable. A clear contrast exists between the inaccessible areas of the reserve and the open flats, where the plants were visibly stunted and the grass was short due to constant grazing. Large herds of cattle moved about freely as is the norm now.

Tiny mushrooms growing from cattle poop

The first little flower that caught my attention was a Thunbergia atriplicifolia (Natal primrose). Its pale, butter-yellow petals had been neatly eaten away—no doubt by a hungry caterpillar—giving the flower a quirky notched appearance. Nature creates beauty all the time; if you slow down long enough, you will see so much. This hardy, low-growing shrublet belongs to the family Acanthaceae. The genus honors Carl Peter Thunberg, a student of Linnaeus who collected thousands of local specimens in the 1770s and became known as the "Father of South African Botany".

Thunbergia atriplicifolia

Our next eye-catching find was a new leaf of a Berkheya speciosa (skraaldisseldoring) nestled close to the soil. Its deeply lobed, wavy margins were dramatically edged in dark maroon and heavily armed with sharp, spiny teeth. The lobes were neatly curled, exposing the striking contrast of the white, felt-like under-surface against the vivid green of the upper leaf. It is a member of the Asteraceae family. No doubt, these impressive leaves will later give rise to large, bright yellow, daisy-like flower heads during the summer months. Berkheya was named in honour of Johannes le Francq van Berkhey, a prominent Dutch physician, botanist, lecturer, and natural history illustrator. It is a massive genus for South Africa—of the around 75 species known globally, 71 are strictly native here.

Berkheya speciosa

Nearby, Dorothy and Hilary stopped to admire the grey-green, suede-like leaves of a Helichrysum acutatum (sticky everlasting), where rich golden-yellow flower heads sat on long, slender stalks. It belongs to the family Asteraceae, with its genus name beautifully translating from the Greek words for "sun" and "gold." An older Afrikaans common name for this plant is tontelbossie (tinder bush), as early field travelers and trackers would strip the woolly, felt-like hair right off the leaves, dry it out, and use it as a highly effective, slow-burning tinder to catch sparks when starting fires in the veld. Out on the exposed flats, this dense layer of greyish, woolly hairs continues to serve its original purpose, protecting the plant from the harsh sun and minimizing moisture loss in the grassland.

Helichrysum acutatum

Flashes of burnt umber and yellow flowers sitting above distinctly textured, dull sage-green trifoliate leaves could only belong to Eriosema umtamvunense (Umtamvuna eriosema). Looking closely at the dense flower clusters, the calyx lobes and surrounding bracts were heavily clad in long, velvety, spreading hairs, providing a perfect platform for a little spotted leaf beetle that had stopped by. If you turn over the leaves, you will find a finely woolly, grey-to-white underside peppered with tiny, distinct yellow glands. We didn’t flip a leaf over to check for them on this visit—a good reminder to look out for them next time! Belonging to the family Fabaceae, its specific name umtamvunense is a deeply specific geographical title meaning "belonging to the Umtamvuna," referencing the fact that this rare, Endangered (EN) species is a narrow endemic restricted strictly to the ancient Msikaba sandstone formations around the Umtamvuna River gorge. Belonging sounds just too wonderful.

Eriosema umtamvunense with spotted leaf beetle

A white, flat-topped flower head sparked our weekly Thursday debate: Crassula alba or Crassula vaginata (yellow stonecrop)? Dorothy sagely declared that the difference between the two still eludes her, so after photographing it closely, we moved on. Fortunately, according to the official SANBI Diagnostic keys, there are a few ironclad, definitive features to help tell them apart. Back home, a look at these finer details settled the mystery. Crassula vaginata belongs to the family Crassulaceae, a genus named after the Latin word for "thick" or "fleshy," which perfectly describes the succulent leaves that give it a water-storing edge. Local isiXhosa tracking traditions call it uphuncuka—referring to this slippery, fleshy survival mechanism. While it looks nearly identical to Crassula alba, it is distinguished by highly prominent leaf sheaths that wrap like a collar longer than 10 mm around the stem. Crucially, our close-up photos confirmed that the stem internodes were completely smooth and hairless, clinching the ID for Crassula vaginata over the rough-haired stems of Crassula alba.

Crassula vaginata

A cheerful gold daisy flower sat proudly atop a remarkably long, wire-like stem, swaying above a dense mound of small, feathery, deeply lobed leaves. It was Euryops leiocarpus (smooth-fruited resin bush). A tiny black-and-yellow grasshopper observed us from its perch on top of the petals. Euryops leiocarpus belongs to the family Asteraceae, its genus name translating from the Greek for "wide eye" to perfectly match these open golden daisy heads. Highly localized and indigenous to our coastal sandstone slopes and grasslands, its specific name leiocarpus means "smooth fruit," pointing to its bald seeds. It handles the elements of the ridges beautifully, and carries a neat history: many species in this genus naturally coat their woody stems in a sticky, highly flammable aromatic resin, which historically led early field travelers and trackers to gather the branches to burn as long-lasting veld torches.

Euryops leiocarpus

Hilary was perched on a nearby rock as happy as a Cheshire cat, pointing out a little Wahlenbergia huttonii (Hutton's bellflower). Small, precise, deep lilac flowers balanced on slender, wire-like stalks that swayed gently in the grassland breeze. Classified under the family Campanulaceae, the genus honors Göran Wahlenberg, a Swedish professor of botany, while the species honors Henry Hutton, a dedicated 19th-century South African plant collector. It is well-adapted to our rocky sandstone grasslands. Next to the Wahlenbergia huttonii, tucked among the burnt branches of a protea, was a Cycnium racemosum (large mountain ink flower). Its fragile, large pink blooms stood out dramatically against the blackened wood. It is also referred to as the mushroom flower because it reliably bursts into bloom right alongside the arrival of the mushroom season. Cycnium racemosum belongs to the family Orobanchaceae, its genus name stemming from the Greek word for a swan to match the elongated, elegant corolla tube that bends gracefully like a swan's neck. It is a root hemiparasite, tapping into neighboring grasses for water while its own green leaves photosynthesise. It carries a fantastic history in the veld; early travelers and local communities would collect the blooms to make a highly functional substitute for writing ink, as its bruised tissues naturally bleed a dark fluid that dries to a permanent pitch-black, a trait mirrored in its traditional isiZulu name, uhlabahlangane. This plant is definitely for our botanical artist Gail.

Wahlenbergia huttonii

Cycnium racemosum

The day was stunning; the sun was warm and comforting, but the wind was at our heels. Weaving in and out of the rocks, searching for plants—this is what life is about. In a small, soil-filled crack, a Tritonia disticha (red tritonia) waved around in the wind, its bright red, trumpet-shaped flower catching our eyes. Tritonia disticha belongs to the family Iridaceae. It grows from a fibrous-coated underground corm. The erect, sword-shaped leaves are arranged in a distinct, fan-like, two-ranked pattern, which gives rise to its species name, disticha. The funnel-shaped, bilaterally symmetrical flowers are typically borne along lean, wiry, branching spikes.

Tritonia disticha

Around a boulder, growing in a crevice, was Dalbergia obovata (climbing flat bean), a robust scrambler representing the family Fabaceae. This tough climber had tightly anchored itself into the rocky fissure, using its modified, tendril-like hook branches to rise to new heights. Coming closer, you were treated to an intimate look at its glossy, dark green compound leaves, which framed sprawling, heavily branched sprays of minute, creamy-white flowers. These delicate, pea-like blossoms clustered together in the leaf axils, their soft cream tones standing out beautifully against the deep golden-brown hue of the young, woody twigs.

Dalbergia obovata

The jolly lilac flowers of a Nemesia species (cape snapdragon) smiled up at us from among the rocks. We knew we had found a Nemesia, but deciding between Nemesia caerulea and Nemesia denticulata kept us debating. Because both species can feature sessile, sharply toothed leaves along their stems, looking at the foliage didn't help us settle it. The only way to actually tell them apart is to peer right into the mouth of the flower to see if the colourful pouched palate is covered in fine, tiny hairs, which is a feature of Nemesia caerulea, whereas Nemesia denticulata remains completely smooth and hairless. It was an oversight on our part not looking closely enough—another reminder that botany can’t be rushed! This genus belongs to the family Scrophulariaceae. The distinctive pouch or short spur at the base of the lower flower lip acts as a specialized nectar guide, perfectly evolved to welcome visiting insect pollinators.

Nemesia species

It was amazing how remarkably neat and pretty the next plant was, quietly tucked low into the grassland matrix. Dyschoriste burchellii  small, pure white flowers resting against equally neat foliage, where the old, long, brown, wiry styles from previous blossoms made the entire cluster look like a stylised arrangement. Belonging to the family Acanthaceae. It is highly recognizable by its calyx lobes, which are densely fringed with fine white hairs. Mixed among these hairs are tiny, scattered, stalked glands. To the naked eye, they remain hidden, but peer through a hand lens and they look like delicate dew droplets clinging to the green sepals. 

Dyschoriste burchellii

Grewia occidentalis (cross-berry) belongs to the family Malvaceae. This scrambling shrub or small tree is well-adapted to rocky ridges, forest margins, and open woodlands across South Africa. It gets its common names from its distinctive, four-lobed square fruits that sit together in the shape of a miniature cross, turning a deep reddish-brown when ripe. These sweet, edible fruits are highly relished by humans—often used to make traditional jams—as well as by monkeys and a variety of birds like louries and mousebirds, which act as primary seed dispersers. The nutritious foliage is actively browsed by game like bushbuck and duiker, while the plant serves as a vital larval host for butterflies like the rufous-winged elfin and the buff-tipped skipper. It is a striking plant, but certainly not for a small garden, as they are vigorous scramblers!

Grewia occidentalis

The unbranched flowering stems of Hypoxis hemerocallidea (African potato / inkomfe) bear six-tepalled, star-like yellow flowers that open sequentially from spring through summer. They greet the warm morning sun, radiating a brilliant warmth against the surrounding green growth. I keep a special place in my heart for them, though I must confess I always think "hemorrhoid" when trying to recall the specific name—which is a highly effective memory trick, provided you don't accidentally blurt it out loud! Hypoxis hemerocallidea belongs to the family Hypoxidaceae. It is easily distinguished from its hairless relatives by its sickle-shaped, strap-like leaves that are neatly arranged in three rows and heavily fringed with distinct white hairs.

Hypoxis hemerocallidea

We literally stumbled upon Alepidea peduncularis as the ground was very uneven, but a close examination of its structural anatomy and precise habitat leaves no room for debate about its identity. Within the Umtamvuna Nature Reserve, both species occur, but Alepidea peduncularis is far more common and widely distributed. While the elusive Alepedia amatymbica is a localized specialist restricted to deep, shaded river gorges, wet forest margins, and damp cliff seeps—and heavily depleted outside protected borders due to traditional medicine over-harvesting—Alepidea peduncularis thrives as an open-terrain generalist across the flat, sunny plateaus covered in Pondoland Sandstone Sourveld grasslands.

The definitive proof lies in the immutable shape of both the foliage and tuhe flower architecture captured in the photos. Looking closely at the basal rosette in the right panel, the leaf blades taper smoothly and gradually into distinct cuneate (wedge-shaped) bases where they meet the ground—completely lacking the broad, squared-off (truncate) or deeply heart-shaped (cordate) leaf bases that remain constant across all Alepidea amatymbica variations. This diagnosis is further solidified by the inflorescence details in the left panel; the star-like flower heads display a neat, symmetrical ring featuring a highly distinct alternating pattern of larger and smaller bracts totaling 8 to 11. This structural layout completely rules out Alepidea amatymbica, which is strictly restricted to a lopsided arrangement of exactly 5 main unequal bracts. This combination of an open-grassland habitat, a wedge-shaped leaf, and a multi-bracted flower structure firmly diagnoses this specimen as Alepidea peduncularis.

Blending into the surrounding green was Euphorbia natalensis (Natal spurge), representing the family Euphorbiaceae. Spiky green leaves alternate up the stem to the top, where they give way to pale, greenish-yellow flowering branches that create a subtle splash of texture in the grass. Like all members of its genus, it features specialized flowering structures called cyathia and contains a milky, latex sap that is highly irritating to the skin and eyes, serving as a powerful deterrent against herbivores.

The vibrant orange flowers of Watsonia bachmannii (Pondoland bugle lily) were not easily ignored—except, of course, if you have a total aversion to orange, in which case you had best look away and move right on! Watsonia bachmannii belongs to the family Iridaceae. It is a rare, range-restricted endemic confined strictly to the specialized, moisture-rich sandstone ecosystems between the Umtamvuna and Mkweni rivers. It is officially assessed as Vulnerable (VU), with remaining wild subpopulations continuing to face significant, ongoing decline due to overgrazing, habitat degradation, and disruptions to local water tables.

As we walked, we noticed Hilliardiella hirsuta (quilted-leaf vernonia) in various stages of its life cycle. Plants simultaneously showed fresh flowers alongside developing and fully mature seed heads. Its leaves are luxuriously quilted and covered in fine hairs, featuring sharply toothed margins where tiny, precise points protruded right from the tips of the teeth. The frilly, deep purple, composite flower heads mature sequentially into small, ribbed fruits topped with a crown of fine, bristly hairs; these act as built-in seed parachutes perfectly designed for wind dispersal across the open flats. It is a member of the family Asteraceae.

Walking between the ancient sandstone boulders, the magenta-to-purple flower spikes of Ledebouria asperifolia (rough-leaved African hyacinth) were just so lovely. I have long held a fascination for Ledebouria, and finding them always feels like discovering hidden jewels. This resilient geophyte belongs to the family Asparagaceae. Its strap-shaped, olive-green leaves are beautifully marked with dark purple spots, but what truly sets it apart is its unique texture. Right at the bottom of the leaves on the underneath side—the basal underside—check for the diagnostic rough bumps (asperities). Arising from a small underground bulb shielded by dark brown outer scales, its early summer flower stalks bear dense, upright clusters of small, bell-shaped blossoms with recurved petals and distinct violet filaments.

As we explored around the edge on a narrow shelf, we had to make our way around a Maesa lanceolata (false assegai / valsassegaai) in full flower. This narrow ledge brought us face to face with its sprawling, heavily branched sprays of minute white flowers, which stood out beautifully against the golden hue of the twigs and green foliage. This species belongs to the family Maesaceae, though modern global classification systems have since lumped it into the broader primuloid family, Primulaceae. A highly variable, fast-growing large shrub or small tree, it thrives along forest margins, streambanks, and moist cliff lines. It features large, lance-shaped leaves with distinct, sharply toothed margins and prominently raised veins underneath. The individual, microscopic flowers are bell-shaped and give rise to massive, dense clusters of small, spherical berries that turn a creamy-white or yellow when ripe, and are enjoyed by many fruit-eating birds.

Maesa lanceolata

Around the corner, following Anne’s directions carefully as we were closer to the edge than we realized, we saw the delicate, trailing Oldenlandia tenella (slender oldenlandia). Its tiny, round leaves glistened as it clung tightly to the damp sandstone, bearing chaste little white flowers that poked through the green mat. Oldenlandia tenella belongs to the family Rubiaceae. This delicate, prostrate perennial herb features slender, trailing stems that readily root at the nodes, allowing it to form dense, creeping mats over moisture-rich substrates. It develops small, ovate-to-rounded leaves and bears tiny, four-lobed, star-shaped blossoms on lean, capillary-like stalks. It is perfectly adapted to thriving within shaded rock crevices, damp forest floors, and mist-laden sandstone cliffs throughout the eastern summer-rainfall regions of South Africa.

Oldenlandia tenella

Hanging down right next to the Oldenlandia were the leaves of a Gerbera ambigua (botterblom). The wavy margins of the rich green leaves hinted at the dense, snow-white felt hidden underneath, rolling slightly over the edges to create a crisp, painted outline against the glossy upper surface. This stemless, tufted perennial daisy belongs to the family Asteraceae. It features highly variable, prostrate leaves that form a low basal rosette hugging the sandstone rock face or soil. The leaves are shiny green above but completely white- or yellow-felted with dense, velvety hairs underneath, a specialized design that helps reflect intense sunlight and minimize moisture loss on exposed cliffs.

Gerbera ambigua

Below, winding around the grass for support, was one of the sweetest flowers, Caesia contorta (blue grasslily / sokkiesblom). It displayed little lilac stars with delicate white filaments with purple bands, topped with bright yellow anthers protruding from the center, creating a beautifully detailed miniature arrangement nestled low in the grass. Caesia contorta belongs to the family Asphodelaceae. This evergreen, rhizomatous geophyte forms sprawling, untidy tussocks of grass-like, grey-green leaves. Its short-lived flowers open sequentially in the afternoon, featuring petals that characteristically twist and wind tightly together as they wither, which gives the species its name. Its tri-colored stamens resemble tiny striped sock cuffs, giving rise to its Afrikaans common name.

Caesia contorta

Hilary asked what Helichrysum the bunches of white and yellow flowers belonged to. It was Helichrysum felinum (strawberry everlasting). It was easy to see why it caught her eye; the densely crowded terminal clusters of small, crisp white papery bracts surrounding flat, bright golden-yellow centres are very appealing. Calling them "flowers" is actually a very common mistake! What look like traditional white petals are not petals at all, but rather specialized, modified leaves called involucral bracts that form a protective cup around the tiny, true yellow flowers tightly packed into the center. Helichrysum felinum belongs to the family Asteraceae. The specific epithet felinum comes from the Latin word for "cat-like," dating back to 1737 when botanist Paul Hermann noted that the plush, velvety texture of the unopened buds and woolly stems perfectly resembled a soft cat's paw.

Helichrysum felinum

Walking slowly down the steep embankment there was a single Disa versicolor. At a quick glance it didn’t look like much, but when you got down and had a look at the open flowers they were really quite captivating. This specific name, versicolor, means "variously coloured," referencing how the blooms transition from warm apricot-orange and deep ochre on the hood to a pale greenish-yellow base. A member of the orchid family, Orchidaceae, the flower features outer sepals framed by deep ruby-red margins. Looking directly inside reveals a lime-green with dark magenta-burgundy spots. Glistening right at the heart is a tiny, frosted-white viscidium (a specialized reproductive structure), which secretes a sticky fluid to cement pollen packets onto visiting insects as they crawl inside seeking nectar.

Gail came back with a few lovely discoveries of her own. Not all who wander are lost, some are just botanising! Disa sagittalis is a charming terrestrial orchid belonging to the family Orchidaceae. This lithophytic perennial features up to ten narrow leaves tightly clustered in a neat basal rosette. What immediately captures the eye are the slender, erect flowering stems that support dense, striking spikes of pale lilac flowers. Then Gail saw Lotononis bachmannii, a rare and narrow Pondoland endemic representing the family Fabaceae. Its small, trifoliate leaves and loose cluster of delicate, purple-blue pea-like flowers is no doubt what caught Gail’s eye.

Then we saw an interesting plant with obovate, opposite leaves and a dramatically tapering seed pod densely covered in soft, fleshy prickles. It was Schizoglossum atropurpureum subsp. virens. Choosing this genus and species comes down to a perfect matching of keys. While many members of the family Apocynaceae produce smooth, twin pods, the genus Schizoglossum is famous for these solitary, heavily textured fruit follicles armed with soft prickles. When you couple that distinctive fruit with oppositely arranged leaves that are distinctly obovate, it eliminates lookalikes and points straight to this species.

Yellow is such a happy colour and Phymaspermum acerosum (geelblombos), wears it so well. Its large, flat-topped flower heads formed massive, bright yellow clusters that looked like vibrant drops of sunshine capping the vegetation. Belonging to the family Asteraceae, this robust, multi-stemmed perennial shrub is an excellent example of an opportunistic pioneer species. Its names provide the perfect identification guide: the genus Phymaspermum comes from the Greek words for "swelling" and "seed" (referring to its distinctively shaped fruit), while acerosum stems from the Latin for "needle-abundance," a nod to its crowded, exceptionally fine, needle-like leaves. Hidden right at the base of the midrib on the underside of each feathery leaf is a large, gland-like swelling. The individual golden flower heads lack outer ray petals, developing instead into tight, button-like discs that hold their brilliant colour exceptionally well.

Phymaspermum acerosum

The Polystachya pubescens (amabelejongosi) were in full form, and clusters of these warm yellow orchids decorated the grassland. Belonging to the family Orchidaceae, this resilient, lithophytic orchid is perfectly at home amoung the exposed sandstone rock faces. It forms tight groups of small, egg-shaped pseudobulbs that store water, allowing it to withstand the harsh sun and winds on the ridges. The striking, hairy-backed yellow flowers are inverted, presenting their distinctively red-pubescent, three-lobed lips uppermost to incoming pollinators, creating a brilliant splash of gold against the ancient sandstone.

Tucked neatly into a shaded, rock-strewn nook beneath the canopy, we spotted the neat fan of leaves belonging to Rangaeris muscicola. It was incredibly exciting to catch it right as it was producing an emerging inflorescence, with a single, slender, light-green flower bud curving outwards on a remarkably long nectar spur. This resilient lithophyte belongs to the family Orchidaceae. It secures its tight, V-shaped fan of stiff, leathery leaves directly to the sandstone with thick, fleshy grey roots. When that long-spurred bud finally opens, it will reveal a pristine white, star-like bloom that releases a heavenly, sweet scent late in the evening—a fragrant invitation specially designed to attract night-flying hawkmoths.

Rangaeris muscicola

Twining its way gracefully through the surrounding vegetation, we came across Rhynchosia totta (yellow climbing bean). This delicate scrambler is easily recognized by its trifoliate leaves with narrow, linear-oblong leaflets. A closer look at the leaflet junction reveals a wonderful set of microscopic keys: a dense fringe of fine, spreading hairs and two minute, pointed stipels standing out sharply at the base of the leaflets. Belonging to the family Fabaceae, it twines effortlessly through the vegetation.

Anne called me over to see Delosperma carterae (Pondoland ice plant) flowering on the pavement sandstone. The white flowers with their soft pink centers are a breathtaking sight, glistening vibrantly against the harsh, baked rock face. This creeping succulent belongs to the family Aizoaceae. A rare endemic strictly localized to these specialized pavement sandstones of our region, it is masterfully engineered to handle the extreme heat of the open flats. Its low-growing, fleshy green leaves are covered in thousands of tiny, shimmering water cells that reflect the scorching sun like microscopic ice crystals, allowing it to preserve precious moisture and burst into these daisy-like blooms right when everything else seems to bake. 

Delosperma carterae

It was so amazing to find the next plant, and Uschi instantly identified the stunning, deeply lobed leaves as Dioscorea multiloba (wild yam). Belonging to the family Dioscoreaceae, this climbing tuberous perennial twines gracefully through the vegetation. True to its specific epithet, its most eye-catching feature is its large, highly decorative leaves, which are consistently and deeply split into three, five, or seven sharp lobes with prominently patterned veins. It definitely added a beautiful, architectural texture to our day.

Dioscorea multiloba

Close by, the trifoliate leaves of Searsia acocksii (Pondo climbing currant) caught my eye. The vibrant green leaflets, beautifully patterned with pale lime-green veins and an elegant pink flush on the fresh new growth, made it stand out immediately. The small, sharp, backward-curving spines along the stems clinched the ID. Belonging to the family Anacardiaceae, this rare, range-restricted scrambler is a South African endemic strictly confined to the scarp forests and rocky sandstone river gorges of the Pondoland Centre of Endemism. It is officially assessed as Near Threatened (NT), primarily because its sensitive forest-margin habitat faces ongoing pressure from frequent, intense grassland fires. Finding it climbing securely among the rocks is a heartening reminder of the ancient, hidden pockets this reserve works so hard to protect.

Searsia acocksii

Hilary called Uschi over to look at Pachycarpus coronarius. It created quite a bit of excitement among the group! This fascinating plant belongs to the family Apocynaceae. What makes this species so breathtaking is the sheer scale of its blossoms; the flowers can grow to be roughly the size of your palm. While they feature somewhat understated, dull greenish-white base tones heavily mottled with deep purplish blotches, they completely make up for it with their massive size and intricately sculpted, crown-like corona lobes that spread boldly outward from the central staminal column. Hilary certainly earned the title of chief spotter on Thursday!

Pachycarpus coronarius

Thursdays are all about plants, but finding the tiny creatures that rely on them for food or that are responsible for their pollination is super exciting. So when I spotted the little yellow caterpillar dressed with bright red spines issuing an explicit warning not to touch eating away on a Clutia species leaf, I was absolutely thrilled. It was the larva of Sporetolepis platti, belonging to the family Limacodidae. The body is heavily armed with highly specialized, venomous, spine-like stinging hairs (urticating setae) arranged in neat clusters. Touching these spines releases a potent toxin that causes a severe, burning sting—making it a formidable and beautifully defended little resident of our reserve.

Sporetolepis platti

The wind was howling, making standing difficult and photographing almost impossible. So we quickly stopped to admire Lotononis lotononoides (Pondo lotononis) and then moved on. Deep warm purple pea flowers snuggled into the grey-green foliage. Belonging to the family Fabaceae, this prostrate perennial is a rare endemic restricted strictly to the sandstone grasslands of the Pondoland Centre of Endemism. Its specific name, lotononoides, translates directly to "looking like a Lotononis," which is a fun botanical quirk because it is named after its own genus to highlight how perfectly it embodies the classic features of this plant group.

Lotononis lotononoides

We turned back towards the Jimnys, the wind thrashing at our backs as we negotiated our way through boulders and Smilax anceps. Gail and Dorothy had climbed into the Jimny to shelter from the wind. Heading back into the teeth of a howling Pondoland gale was a rugged end to the afternoon, but it felt like the perfect punctuation mark for a group that loves nothing more than a wild, beautifully unpredictable Thursday botanising.
