Assessing a private grassland (Thursday 19 September 2019)

The owner of a property overlooking the lower Umtamvuna River gorge and the Red Desert Nature Reserve asked whether it would still be a good idea to undertake a management burn of his grassland. We advised that it was now too late but agreed to assess the condition of his unburned grassland as well as a section that had been burned earlier. We met near the Red Desert Nature Reserve and drove along a steep farm track to reach the grassland. The grassland was wet after overnight drizzle so we all donned waterproof gear and set off.

Very soon we started seeing flowers in a mowed track and in the adjacent grassland, despite the obscuring effect of the tall grass. Here we found Hewittia malabarica, Freesia laxa, Ledebouria petiolata, Gomphocarpus physocarpus, Dierma igneum and some well disguised Acrolophia coclearis. Protruding well above the dry grass were several Drimia echinostachya, a few Eriosema salignum and Selago tarachodes. Kohautia amatymbica waved their white flower clusters at the end of grass-like stalks.

However it was only when we reached the burned section that we saw the full botanical richness of this grassland area. Dyschoriste burchellii clustered around some early Helichrysum pannosum shoots. There was a tangle of Geranium flanaganii and several Eriosema umtamvunense as well as bold Chamaecrista comosa flowers. Splashes of white clusters of Callilepis laureola overshadowed some discrete Acalypha wilmsii.

We found Argyrolobium rotundifolium with its yellow-turning-orange flowers, Ajuga ophridis, and three Berkheya species: B. setifera, B. speciosa, and B. umbellata. There were some Commelina africana, Convolvulus natalensis, Cyanotis speciosa and Eriosema kraussianum.

Gladiolus longicollis bobbed their heads in the breeze -- most of these flowers were boldly marked, in contrast to the plain white we normally see. There were several Hilliardiella hirsuta with their large purple inflorescenses. We found Ipomoea crassipes and despite its attractive markings, a well-camouflaged mantis on a Schizoglossum atropurpureum subsp. virens.

Clustered near some rocks was Plectrnthus hadiensis, Polygala myrtifolia  Psychotria capensis, and Psoralea arborea. Out in the open we found several Ruellia cordata, Scabiosa columbaria and Ornithogalum saundersiae.

With the drizzle starting again we turned back towards the shelter of the vehicles finding Cucumis zeyheri, Euryops leiocarpus, Helichrysum pallidum, Thunbergia atriplicifolia and Watsonia densiflora along the way.

We also found the first Sisyrantus imberbis of the season and a few of the short spur form of Eulophia parviflora.

Manilkara and Smedmore (Thursday 12 September 2019)

As we needed to check on any progress with the Dovyalis lucida trees at Manilkara Meander, that was our first destination for the morning. While the Dovyalis proved to have no sign of flowering there were still several other plants in flower: Gerbera natalensis, Othonna natalensis, Ursinia tenuiloba, Erianthemum dregei, Acridocarpus natalensis, Salacia gerrardii, Leucadendron spissifolium subsp. oribinum and a very floriferous Asparagus. The Petopentia natalensis were at their peak, displaying their flowers at the tops of shrubs and trees.

After checking the Dovyalis we made a quick circuit around this grassland and its cliff edges before heading over to Smedmore to have lunch and see more flowers.

In the forest where we sat enjoying lunch, Gail found some Scadoxus membranaceus plants in fruit. We left the forest and headed to the grassland. We were soon amongst the flowers, finding Ledebouria ovatifolia and Eriospermum mackenii. Not far from these were a few Euphorbia bupleurifolia, several of which were in a very attractive state of flowering.

Once over the brow of the hill we found the first of the Anemone caffra flowers of this season. Some new buds of bracken fern Pteridium acquilinum made interesting shapes. We made a circuit of the grassland, ending up near the forest margin where we found Geranium flanaganii and Burchellia bubalina in flower.
