Sodden during a visit to the big Lydenbergia abbottii (Thursday 23 January 2020)

Despite threatening rain, most of the group set off for "Tony's tree", a large but difficult to find Lydenberrgia abbottii situated in the forest along the eastern flank of the Bulolo River gorge. I stayed in the herbarium doing the final steps of loading the BRAHMS database onto the computer. Once I had finished with the computer work I set off after them expecting to have a difficult job tracking them in the dense forest even though I knew where they were heading.

On the way I saw Alectra sessiliflora, Lasiosiphon kraussianus, Gymnanthemum corymbosum, Cyphia elata, Satyrium trinerve, Exochaenium sp. nov, and numbers of Thunbergia atriplicifolia. Just before I reached the forest, I found a small cluster of the yellow form of Tinnea galpinii that only seems to grow along this short section of path.

Fortunately I caught up to the rest of the group before the headed off in the wrong direction and soon we were at the big old Lydenbergia abbottii, fondly known as "Tony's tree". The soil has steadily eroded out from under this venerable cluster of trunks so that the tree is leaning out over a steep slope leading down to the Umfafaza River, a tributary to the Bulolo River. The tree's stability was not enhanced when a large Harpephyllum caffrum collapsed on it a few years ago but most of that has rotted away now.

Once we had taken the obligatory photo with the old tree, we decided to clamber down to the Umfafaza River that we could hear tumbling over rocks below us. We reached the river and set about unpacking our lunch when the heavens opened with a heavy downpour. Fortunately we were under dense forest growth, which shielded us for a while but before long the trickles reached us and we decided to head back - no easy task as the rocks and surrounding vegetation was all drenched. We just had time to capture a few photos (Scadoxus multiflorus subsp. katharinae and Plectranthus hilliardiae) at the streamside before slipping and sliding home.

Succour in Cascades pool (Thursday 16 January 2020)

After a series of very hot and humid days with night-time temperatures in the upper twenties (degrees Celsius) we decided that on a clear day the only option for a walk was to head to the pool at Cascades. We drove as far as we could, that left us with a walk of less than a few hundred meters down to the stream and the entrance to the forested gorge. It did not take us very long to push our way through the forest undergrowth and get to the open rocks at the top of the Cascades pool. After the well-distributed rain of the last weeks, the stream was running strongly but that did deter us from leaping (careful of the slippery rocks) into the clear water of the pool. On this occasion the weather was hot enough to ensure that for the first time we had everyone in the pool.

The Rare Emplectanthus dalzellii  was flowering - this was another reason for visiting this area although the pool was the major draw-card. There were several plants twining up into the forest under-storey shrubs while displaying their flowers on axilliary peduncles to best effect.

After enjoying a relaxed lunch at the side of the stream we slowly made our way out of the forest and up the hill to the vehicles. On the way we found a the last of the Erica cerinthoides in flower, a few Helichrysum allioides and  Monsonia praemorsa.

Pachycarpus, Acridocarpus, Streptocarpus and more at Smedmore (Thursday 9 January 2020)

With rain forecast after midday, we decided to walk the clifftops at Smedmore where we would always be reasonably close to the vehicles. We checked to see if the usual crop of Riocreuxia torulosa was flowering but instead there was Cryptolepis capensis with its long white twisted petals. We walked on to see that most of the colony of Pachycarpus coronarius had already set fruit. Growing in a small cluster of shrubs we found Dioscorea quartiniana flowering - previously we had thought this plant was a D. multiloba although we had never seen it in flower. Not far away we found another common Dioscorea species, D. cotinifolia.

The adjacent grassland hosted Eucomis autumnalis, Indigastrum fastigiatum and a few Pachycapus coronarius that were still flowering. At the forest edge we found a Solanum giganteum. Scrambling down the steep slope below the rocky edge we came across a large colony of Streptocarpus formosus -- rather difficult to get a decent photograph without holding onto nearby trees with your teeth.

Clambering back out of the forest we found the first of many Eugenia erythrophyllla trees in flower. As this was the first time many of us had seen such prolific flowering from these Eugenias, we surmised that they flower only infrequently. Near to the first of these was a small Homalium rufescens and a bit further along we found several Schrebera alata  bearing their pink and white sweet-smelling flowers.

 Again venturing down the slope, Anne found a single flower on Mimusops obovata. A nearby Garcinia gerrardii was bearing some immature fruits and nestled between large rocks were two Aspalathus dahlgrenii. Tracy found two climbing plants emerging from gaps between some rocks --  Pilogyne scabra and Coccinia mackenii.

Back at the cliff edge we found Osyridicarpos schimperianus in flower and Dorothy collected a specimen of Oncinotis tenuiloba. Back out in the grassland there were Dimorphotheca fruticosa and after persuading a bud to open, we found an undescribed Pachycarpus - something that might be a hybrid with P. coronarius.

Next we found several Pavetta lanceolata shrubs poking their flowering tops out above the other trees. As we entered the edge of the forest we spotted Dalechampia capensis and once we had pushed our way through the undergrowth, we could see several Calodendrum capense proudly displaying their flowers as patches of pink in the otherwise green forest.

Turning the corner we found a single flower of Hyperacanthus amoenus.

After a brief stop for lunch on some ant-free rocks (at this time of the year it is difficult to find a place to sit without getting attacked by pugnacious ants) we headed back before the promised rain. As we entered the Beacon Hill gate of the reserve we saw several Habenaria dives.
