A late summer visit to Kwazamane (Thursday 19 March)

While returning from a visit to the Western Heights earlier in the week we encountered Zamani Mhlongo, the new manger of the farm we have to traverse to get to the Western Heights. We were delighted when he expressed an interest in accompanying us on our walks in the reserve and he joined us for today's visit to Kwazamane. As the track is yet to be cut (Zamani will get to this task in due course) we drove to the old picnic spot and parked there in the shade of tall macadamia trees. The undergrowth on the other side of the track was carpeted with flowering Plectranthus ciliatus.

We walked down the track next to the macadamia orchard towards the reserve. There were swathes of Erica aspalathifolia growing through the Stoebe vulgaris thickets - the area is in need of a management burn to get the woody growth under control. We also found Desmodium setigerum flowering in the track.

We reached the reserve fence and easily scaled this where some strands had broken. We crossed over to a rock outcrop to check the status of a small group of Ypsilopus longifolia, finding Indigofera herrstreyi along the way. The Ypsilopus were sporting flower spikes but it will be some weeks before these are flowering - as is often the case, these plants are on a vertical rock face with a considerable drop below them. Nestled between rocks was a Streptocarpus haygarthii. We then headed back to the firebreak along the fence finding a group of Disa polygonoides in a streamside wetland. There were also several Dierama igneum in flower along this section.

We crossed the next streamline and in the adjacent wetland found several Habenaria woodii, more Disa polygonoides and the last of the Melasma scabrum.

We reached the point where the boundary fence terminates at the top of the cliffs above Outeniqua Falls gorge and stopped to enjoy the spectacular view of the water cascading over the falls.

Heading back along the clifftops we found some Craterostigma nanum on the rock sheets growing next to Crassula ericoides, many in flower. Protruding above the cliff edge was a cluster of buds on Acridocarpus natalitius and below this we could see the large paired follicles on a Petopentia natalensis. Another clifftop resident was a small Loxostylis alata with flowers and colourful bracts on display.

We stopped for lunch with a great view of the Umtamvuna River gorge below us. On the rocks around us there was an Anthospermum hispidulum in flower in a rock crevice and below this was a a Schizaea pectinata displaying its comb-like sporangia.

In a small gully we found Eugenia erythrophylla with a fine crop of ripe and ripening fruits, which some were brave enough to taste. We moved on to the next gully that we crossed using a narrow natural bridge with about a 5 meter drop below us.

On the next rocky outcrop we found Apodytes dimidiata with fruits starting to mature and some buds on Brachylaena glabra. Walking back towards the fence we came across what appears to be an old sinkhole that now has fairly sizable trees growing out of it. Here we found Croton sylvatica and fruits on Dalbergia armata and D. obovata.

While it was still a fairly hot day, there was no longer sufficient sting in the sun to make us want to duck into the shade at every opportunity. A very rewarding walk.

Four Utricularia species in close proximity at Western Heights (Thursday 12 March 2020)

A much reduced group of us set off  for known localities of Habenaria woodii (Vulnerable) to see if it was flowering. When we found the track to Kwazemane still had not been mowed and the grass was about 2 m tall, we opted to go to the Western Heights instead. Fortunately, despite the road not having been used in recent times, there was only a minimum of clearing needed and Gail happily tackled moving one fallen trunk out of the way. We arrived at the Western heights and immediately saw some clusters of Kniphofia in the distance.

We headed towards the nearest of these clumps but soon found ourselves goose-stepping over tussocks interspersed with puddles. Growing in some of these wet patches Utricularia prehensilis were twining up towards the light, and they were in company with slender stems of Oldenlandia rosulata. We reached the Kniphofia and they turned out to be K. linearifolia. There were several low shrubs draped with clusters of the Data Deficient parasitic Cuscuta gerrardii; this is some distance from the other known population of these plants but in the same wetland.   

We staggered back out of the wetland to find a small group of Brachycorythis inhambanensis. Here we also found a few small Aspalathus gerrardii in flower.

Once back onto even footing and dry ground again we found  Buchnera dura and several of the eye-catching Disa polygonoides. In this area we also found a good sub-population of our target plant for the day, Habenaria woodii.

We then found a surprisingly robust clump of the Vulnerable Psoralea abbottii with its needle-like leaves and blue flowers. Scattered in the area were a few Raphionacme palustris forbs with elongated erect fruits, as well as some tall Senecio discodregeanus and a few spikes of Syncolostemon ramulosus.

We crossed the track and headed down towards another wetland area. On the way we saw several Tephrosia polystachya and some Argyrolobium sericosemium.

We headed towards a big cluster of rocks finding Cineraria albicans growing on a ledge and beneath that a big colony of Utricularia sandersonii was growing on the shady, wet vertical surfaces of the rocks. Just below these blue bunny-ear shaped flowers was a small group of yellow-flowered Utricularia subulata also enjoying these conditions. Within 10 meters of these were several patches of Utricularia livida and at the edge of a rock plate was a group of Genlisea hispidula. As all of these are insectivorous plants - growing in these well-leached conditions they need the extra nutrients - the insect population in this area must be having a hard time.

We stopped here in the shade of a tree to enjoy our lunch surrounded by numbers of Watsonia densiflora and a few Asclepias praemorsa. We then headed back up to the top of the nearest rocky hill and found a beautifully marked caterpillar which is likely to be a Hawk-moth larva.

We crossed back over the track and found ourselves in a small patch of Pachycarpus grandiflorus. In a crack in a rock there was a Psychotria capensis bearing red fruits. We crossed a small water-filled depression and then found a clump of Psoralea glabra with blue flowers and a few Pycnostachys reticulata.
