Western Heights burn revisited

The burned area we visited on the 7th May (apparently this was an arson burn) had produced very little in the way of flowering species so we thought it might be worthwhile revisiting the area to see if anything more had since sprouted. It was a day after a cold front had passed through and it was overcast, windy and cold but undeterred, we headed across to the Western Heights and stopped where we had previously parked.

What a difference! The ground was covered in flowers - many of these species were flowering way earlier than normal but this was probably stimulated by the early burn and a little rain. With these riches in front of us it was difficult to wait for our tea addicts to get their fix. Soon we set off and species lists were being recorded and cameras were snapping.

The daisy family (Asteraceae) were the best represented with many Helichrysum species, two Afroaster species and several Berkheya, most numerous being Berkheya speciosa. The Helichrysum ecklonii were at their best with some of the new flowers bright pink.

It was interesting to see two species of Afroaster flowering in close proximity to each other; Afroaster hispida (previously called Aster bakerianus with hairy stalks) and A. serrulatus (previously called Aster harveyanus).

Interspersed amongst these were Acalypha peduncularis, Clutia monticola, Eriosema kraussianum, Commelina africana and Hebenstretia dura.

A bit further down the slope in a wetland area the Gladiolus longicollis were flowering well. It is interesting that many of these flowers sport double heads. Not far from these we found a number of spikes of Gladiolus wilsonii.

Up tight under a rock outcrop we found several of what we prefer to call Merwilla kraussii as these are so different from M. plumbea (formerly Scilla natalensis). On the rocks above them we were very happy to find Utricularia sandersonii with their pale, delicate flowers.

Also on the rocks we found the only orchid in flower today - a Polystachya pubescens.

Heading back up the slope we found some of the endemic Lotononis bachmannii in flower, as well as a few Graderia scabra.

A visit to Gogosa's forests and grassland


This Thursday's outing was moved to Friday to accommodate visitors from Durban -- Syd Ramdhani and his student Gracious from UKZN Westville came to see Memecylon in the field and Teddy Govender brought his plant knowledge to the party.  We entered the reserve at the northern gate, known as 'Gogosa' and despite the dry conditions, there were several plants in flower in the grassland, such as Dierama igneum, Eriosema kraussianum, Aspalathus gerrardii, Phylica natalensis and Wahlenbergia capillacea.  

Working our way along the forest margin,  we came across Psoralea glabra, Lotononis eriocarpa and Euryops laxus.  The forests along the small streams and gullies in this section of the reserve are different from those in the main Umtamvuna valley, which makes exploring them all the more interesting.    There were several Memecylon bachmannii and even one in fruit so that Gracious got a good feel for recognising her research subject in the field for future reference.  Peddiea africana flowered in abundance, along with Tricalysia capensis and Gerardina foliosa.

Graham, on the comeback trail, elected to stay out in the grassland where the going was a little more even and flat. A warm berg wind was blowing (presaging a cold front) but fortunately the humidity was low so the conditions were comfortable. 

There were Muraltia lancifolia and Agathosma ovata flowering amongst the grass and the Ctenium concinnum were showing their curly pigs' tails. He found a single Eulophia parviflora hiding in the grass. Despite this being our "quiet season" we ended up with quite an impressive list of species in flower.
