More plant rescue surveys: Msikaba North (Thursday 12 January 2017)

Fortunately we were able to drive to the point where we stopped the survey previously, so we could get going quickly. On this occasion we were also accompanied by the site staff of Simply Eviro JV. It took some time to work our way through a small forest patch as there was no cleared survey line but only an overgrown cattle trail. In the forest there were also more species to look at so this first section took some time.

In this forest patch there is a big stand of invasive Solanum chrysostrichum. It is unclear what allowed this species to penetrate the forest, but mans' presence is strongly evident in the forest. Here we saw  Stephania abyssinica in fruit and a large Agelanthus krassianus in a tree. There were several Cussonia sphaerocephala in this forest, the one depicted below being particularly obvious.

Once back in the grassland the progress was quicker as these well-grazed grasslands have poor species diversity. As we crossed a small hill we came across a large stand of the invasive (and probably planted) Plectranthus barbatus, in this case sheltering a patch of Transkei Gold. There were a few Syncolostemon densiflorus on this hillside.

Down this hill and across a small wetland and we were on the last flat section leading to the bridge site. Along this section we saw Leucas lavandulifolia, and apart from a few Pachycarpus species with fruits, there was little else to see other than an Ipomoea simplex  before we reached the edge of the gorge.

There were some interesting plants along the edge of the gorge, including some Pondoland endemic species such as Manilkara nicholsonii and Cryptocarya wyliei and Searsia acocksii.

Walking back after completing this part of the survey
On the way back, Dorothy and Anne and Gail came across two orchid species in flower in a small watercourse, Disa polygonoides and Satyrium trinerve. We saw several other dead stalks of unidentifiable orchid species: some seemed to be Eulophia.

A day trip to Ntsikeni Nature Reserve

January is usually a premier flowering period at Ntsikeni nature reserve. As we expected there to be no accommodation available and as we needed to deliver some equipment to Richard Braby at Underberg, we decided to do a day trip into Ntsikeni with Richard and Julie. It turned out that we were the first visitors to the reserve since the end of December so the accommodation had been there for the asking.

We had carefully selected a day with a forecast of overcast but dry conditions, which would allow us to enjoy a full day in the grasslands. On the way from Underberg, we had a couple of stops -- the first was a small wetland on a farm where we found a few Disa scullyi together with one or two Disa rhodantha.

We continued towards the turnoff at Franklin, keeping an eye out for Nerine appendiculata at the roadside but saw no sign of these at any of the locations where we have previously seen them. Not far after Franklin, driving along a newly tarred road, Julie saw more orchids at the roadside so we made another stop to have a closer look. In this wetland, despite exposure to a large herd of cattle, we found more Disa scullyi and a fairly large population of Satyrium hallackii, ranging in colour from a pale to fairly intense pink . There were also a few Corycium - these will have to be checked to confirm the identity of the species.

After one or two additional stops along the Ntsikeni access road to check out small forest patches, finding a number of flowering Gloriosa modesta in one patch, we finally arrived at the reserve gate and in misty and low cloud conditions headed for the first wetland. Here we found many more Disa scullyi (amongst them an unusual white form), a number of Gladiolus papilio, some very robust Satyrium longicauda and a few very tall Disa chrysostachya. Several Melasma scabrum showed their yellow flowers in this grassy marsh.

There were also some Habenaria schimperiana buds in this wetland but no open flowers. Several Watsonia lepida flowers on the nearby hillsides caught our eyes but we could find none of the mimic species, Disa pulchra, amongst them.

We drove onwards to a dolerite ridge, known to be home to a wide diversity of species. Here it was not long before we found several clumps of Eulophia zeyheriana accompanied by scattered Kniphofia laxiflora.

There was also a patch of the dwarf suffrutex Pygmaeothamnus chamaedendrum with shiny green fruits.

A little further Julie found the only flowering specimen of the very attractive but yet-to-be-described Xysmalobium sp. Soon after this we found ourselves amongst scattered Disa cornuta.

We walked on, starting a stampede of a herd of Black Wildebeest and found a small population of Satyrium hallackii in a wetland. Small flowers of Aponogeton junceus presented their heads above the water here.

Further back towards the vehicle we found a beautiful group of Kniphofia laxiflora. We drove further, unsuccessfully checking other areas for Habenaria schimperiana and then stopping for lunch in the shade of a large tree. After lunch we visited the lodge and greeted the caretaker, Dalu Ngobo, from whom we learned of the availability of accommodation. We then searched the wetlands in front of the lodge where we found only one Disa cooperii. We also saw Epilobium salignumChironia krebsii, and Wahlenbergia rivularis growing close to the stream.

We then set off homeward (passing the only Brunsvigia natalensis we saw in the reserve), but outside the reserve I managed to persuade Richard to make a small detour to explore a roadside cliff.  This proved to be a worthwhile detour as there were many Cyrtanthus epiphiticus in flower on the cliffs.

While we had an extremely productive day, it seemed to us that there were far fewer flowers this year than we normally have come to expect at this time of year. It is possible the flowering has been delayed as we would expect the Habenaria schimperiana to be flowering well by now. Perhaps a return visit might be warranted.
