A wet day: herbarium work and a short walk (Thursday 5 October 2017)

Plans to walk in the Red Desert Nature Reserve had to be shelved when the predicted rain materialised and so it was only a small group that went to the Umtamvuna reserve to continue re-arranging the voucher collection in the HNTA herbarium at Beacon Hill.

We made good progress with re-naming and moving vouchers around into new families and by lunch time we had reached the last cabinet where we called it a day. By that stage the weather had cleared a little although it was still heavily overcast.

Suitably equipped, we walked in a south-easterly direction. It was not long before we came across a good display of Disa stachyoides poking out above the grass, accompanied by the occasional Disa versicolor. On the rocks we saw the first Cyrtorchis arcuata in bloom.

We walked on past a patch of Satyrium longicauda and reached the wetland just before the stream. By this stage most of the Merwilla plumbea flowers were over but there were still a few Disa similis and more Satyrium longicauda amongst a host of bright yellow Senecio brevidentatus.

Starting up the next slope we soon came across a Boophone disticia coming into flower and standing out against the green grass.

 About halfway up the hill we saw the first Silene burchellii, these flowers being fully open and enjoying the overcast, damp conditions.

Down into the next wetland there was a good showing of the Vulnerable, narrow-endemic Watsonia bachmannii, as well as two Cyperaceae species that require some work to get identified to species level.

By then the weather was starting to close in again so we turned back and headed to the office via Ingrid's Falls - not at its best as the stream was flowing with rather muddy water, thanks to some clearing work being done upstream outside the reserve.
