Braving the drizzle at Oribi Flats

As we have had less than our normal rainfall in this early part of the summer season, we were delighted that we were faced with drizzle and a cold wind when we started our walk along the top the cliffs on the north bank of the Mzimkhulwana River. The views from the top of the sheer cliffs down into the gorge are always imposing, but the weather conditions gave these views an untamed feel.

Extreme botanising in wet and windy conditions

It was not long before we came across some flowers also braving the conditions. Tucked under a rock was a beautiful spray of Streptocarpus trabeculatus. Hilliard and Burtt in "Streptocarpus - An African Plant Study" suggest that this species seems to undergo synchronised flowering; we did see others in flower, and also saw several of the more common Streptocarpus haygarthii in flower.

The showers came and went, as did the waterproof jackets as we headed seawards along the cliffs. A target species for this area is Caputia oribiensis but we found no sign of it where it is expected, i.e. hanging down along the cliffs - so we will have to try further down the gorge on another occasion.

We did however find a fairly robust specimen of Seemannaralia gerrardi peeping over the edge of the cliffs, a tree we do not often come across, despite its Least Concern rating in the Red List.

An interesting feature of this section of cliff edge was the number of succulents, particularly Crassulaceae (about 10 species), growing mostly in semi-shaded positions. Below is a photo of a particluarly venerable Crassula ovata hanging out over the abyss.

After having a quick lunch in a sheltered place we went off to a nearby grassland where we have been monitoring the flowering plants over the seasons between bi-annual burns. This area was subject to a management burn on 23 August and is looking very colourful at the moment. Berkheya and Helichrysum are particularly prolific.

Terra incognita - a visit to a grassland near Jolivet

We have been trying to explore more of the home territory of the collector Rudatis and when we were offered the opportunity to visit a grassland on a farm near Jolivet we made arrangements to visit, allowing a suitable interval after a management burn.

Driving down to the grassland through a Eucalyptus plantation we saw a number of Eulophia streptopetala in flower under the trees. We started our walk near a small stream crossing and very soon came across some very showy orange flowered Eriosema cordatum plants amongst the grass.

A little further up the slope we came across the first of a species named after Rudatis, the unobtrusive endangered endemic Searsia rudatisii. This is the fourth locality we have recorded for this species, all within a radius of about 50km.

Scattered around and protruding above the grass were several pale yellow Moraea, probably Moraea graminicola and nodding their silvery bracts and dark red heads were Dierama reynoldsii.

In the shade under a tree were many small white-flowered Hypoxis membranacea and the Eugenia albanensis were also starting to flower amongst the grasses, their white flowers hidden low on the stalks - this is a plant to watch as it produces surprisingly large and delicious fruits.

On rocky plates we found an Asclepias or Xysmalobium - with its flowers yet to open it is difficult to confirm which. With the weather starting to threaten, we returned to the vehicle, and after a brief detour to look at the opposite more rocky slope (where we found a single Drimia uniflora), we drove further.

Just inside a second gate we saw some Kniphofia flowering and stopped to have a closer look, and that led us to what might be the find of the day - a Riocreuxia. As confirmation of the ID is awaited, readers will have to watch this space.

After weathering a short rain shower, we proceeded further up the track. A flash of white in a tree alerted us to a splendid patch of the epiphytic orchid, Mystacidium capense.

At our lunch spot near a small stream we found Pachystigma macrocalyx alongside the stream, and in the open grassland were brightly coloured Sphenostylis angustifolia shrublets.

Higher up the track we found several Rhynchosia cooperi with their bright yellow flowers and at the top of the hill we stopped for the last time to capture a sense of the place.

We came away with a list of more than 200 species which we are sure to be able to add to with further visits.

Blencathra survey

A CREW Target species for October was the Near Threatened Kniphofia littoralis, a species which had previously been collected at the farm Blencathra bordering on the Umtamvuna Nature Reserve, so we made arrangements to visit the farm. The owner, who has the farm on the market, asked that we also give him a list of the species we saw in the grassland - something we collate for every field trip.

As we drove in I noticed a colony of the endemic Aspalathus dahlgrenii (ined.). As the species description has not yet been published, we do not have a Red List assessment of its status, but it is likely, because of its very localised distribution, to be one of the threatened categories. There were about 40 plants in an area of 10 square metres with signs of good recruitment of young plants, but unfortunately none of these plants were flowering.

While we did see some Kniphofia, these were all Kniphofia coddiana, another Near Threatened endemic species. On a rock outcrop there was a very colourful patch of Polystachya pubescens growing amongst the new leaves of a Ficus ingens.

Also nestled amongst the rocks was an early Indigofera herstreyi (ined.), another species awaiting publication. Hidden in the grass were many of the Vulnerable endemic Eriosemopsis subanisophylla, several of which were in flower.

Also in the grass was a single Cycnium racemosum in flower. Some years earlier our group was alerted to a clump of pink "orchids' growing in this area but these turned out to be a spectacular clump of these same parasitic flowers, growing just inside the Blencathra fence.

Just over the rise from there was area covered in many Near Threatened Leucadendron spissifolium subsp. natalense with the male and female flowers clearly evident.

Not surprisingly, with only a fenceline between this grassland and the grassland of the Umtamvuna Nature Reserve, this is a very valuable, species rich, undisturbed piece of grassland - we hope this can remain preserved.

Visit to the Western Heights

It was great to be able to squeeze in a second outing on the same Thursday. Having completed our visit to Blencathra we had a quick teabreak at Beacon Hill and then set off to the Western Heights - a favourite destination - with the intention of looking for Raphionacme palustris and surveying the population of Watsonia pondoensis, both of which we knew we would find there, hopefully in flower.

We first walked to the edge of the wetland, but before we could find any Raphionacme palustris we found ourselves in an orchid-rich patch. The most vivid of these was Disa caffra, but they were surrounded by Disa versicolor, Satyrium longicauda and Satyrium trinerve. The Raphionacme palustris were where expected and in flower.

Our timing was also right for the Watsonia pondoensis to be in flower. Despite the very dense aglomerations of bulbs, this species seems to flower rather sparsely.

We then decided to have our lunch in the shade and coolness under the trees of the Swamp Forest. After lunch, Anne and Graham tackled the job of ring-barking five large black wattle trees that had somehow managed to find their way into this indigenous forest patch.

On the fringes of the forest was a large patch of the regal fern, Osmunda regalis, some of which had produced their fertile terminal parts of the fronds. Leaving the forest brought us back into orchid territory with many more of the same species seen earlier. We took the long way back to the vehicle to avoid having to walk over the many tussocks in the wetland, on the way encountering a Searsia pondoensis in flower, a small patch of Dianthus mooiensis, and then came across a large group of the Vulnerable Watsonia inclinata.

Tony Abbott memorial walk

Walkers from far and wide started gathering at Clearwater early on Sunday morning to celebrate the life and botanical work of Tony Abbott. After many had breakfasted on egg and bacon rolls at the cafe, the walkers were gathered at the viewing deck overlooking the Umtamvuna River gorge to be told a little about Tony Abbott, about the plants of the Pondoland Centre of Endemism that they would be see, and about the routes available to them. Before the start there was a draw for the raffle prize of a botanical painting of a Clivia mineata - one of the plants likely to be encountered along the walk -- and the lucky winner was Audrey Woodley.

The more adventurous walkers headed off to walk the Fish Eagle trail while others restricted their efforts to enjoying the flowers in the grasslands along the escarpment, including a detour a short distance into the Umtamvuna gorge to see the small colony of Clivia mineata plants amongst the rocks.

By late morning the last of the walkers had returned and many enjoyed a lunch at the cafe. A well attended and successful walk on a clear and warm spring day. Thanks to all those who came to support the event!

Visitors from the University of Transkei

Sizwe Cawe, Botany lecturer from the Mthatha campus of the Walter Sisulu University, visited with two honours students to give them some field exposure to plants of the Pondoland Centre. We initially met them at the restaurant at Clearwater which borders on the Umtamvuna Nature Reserve as we also had a need to investigate what was flowering along some of the potential routes for the Tony Abbott memorial walk scheduled for Sunday 4th October.

In cold, windy conditions with rain threatening, we elected to start by walking along part of the Fish Eagle trail down into the Umtamvuna gorge to see if the Clivia were still flowering. Fortunately, while no longer still at their best, there was quite a good show, good enough to justify the walk down to them.

Also in the same rocky patch in the forest we found the rare Cyphostemma rubroglandulosum in flower as well as a small tree covered in lime-green flowers which we eventually concluded was Pachystigma macrocalyx . There was also a creeper - unfortunately not in flower yet - which looks like an Emplectanthus; we will need to visit here again in due course to try to catch it flowering. On the way out of the gorge we came across both sexes of flowers (on separate plants) of Garcinia gerrardii and a few flowers on Rawsonia lucida.

After enjoying lunch at Clearwater, we drove up to Beacon Hill to show the students a different spectrum of plant genera. Orchids are particularly well represented amongst the more obvious yellow, white and pink daisies.

Outing with BirdlifeSA Trogons bird club

On Sunday three of us joined the Trogons Bird Club at the Beacon Hill offices to provide their members with some guidance on the flowers they were seeing during and after their bird watching outing. As the birders had already been busy for some time when we arrived, we only walked for a short distance coastwards from the offices, but nevertheless managed to give them a good exposure to the grassland plants of that area. Some of these were less obvious species like Brachystelma australe, plant they might have missed otherwise.

Their scribe has submitted a very good report on their visit on the Trogons' blog at http://birdlifetrogons.blogspot.co.za/2015/09/outing-report-27-september-2015-beacon.html

Participants: Dorothy M, Graham G, Kate G.

Flowering now (October 2015)

The grassland, particularly the firebreaks which were burned first, are looking great with many flowers. New species are appearing every week so it is no problem visiting the same patches after even a short interval as there is always something new to see.
