Two sites in the Natal Midlands (24 & 26 December 2017)

Escaping the madding holiday crowds at the beach for a quieter stay in Hilton in the KwaZulu Natal midlands gave us an opportunity to explore some grasslands in the area. The first visit was to the Thurlow Game Reserve near Midmar Dam.

Our first stop was for several bright clumps of Aloe ecklonis close to the road. Exploring further we saw an impressive display of Alysicarpus rugosus, with many flowering ground-hugging shrubs dotted around. Xysmalobium undulatum were also doing well here. We made our way towards a reed-bed finding Asclepias flexuosus on the way.

In a wet area near the stream was a single remaining Crinum bulbispermum in flower, several Epilobium salignum and a number of large shrubby Clutia katharinae. Helichrysum rugosus formed a carpet in the drier areas.

Having seen what was on offer at this spot we drove on, stopping briefly to get photos of Vernonia gerrardii before crossing a stream and heading up a hill. At the side of the track we were treated to the sight of a small Erythrina zeyheri in flower and then we stopped at the top of the first hill and started exploring again. There were several large patches of Ipomoea oblongata flowering brightly here. Growing alongside the track were some rather yellow/brown coloured Gladiolus dalenii.

We headed out towards the rocky edge to this hill top where we found a local endemic species, Asclepias woodii, a new species for us. Draped over the rocks was Cyphostemma natalitium and Lablab purpureus spread in between the rocks. There were also clumps of Indigofera hendecaphylla, the occasional patch of Schizocarpus nervosus and a single Lantana rugosa. Low shrubs of Grewia hispida crowded around some of the rocks. Another interesting find on this hillock was Pachycarpus natalensis.

Two days later we set off to visit the Mount Gilboa nature reserve, pausing briefly to pick up Isabel Johnson on the way. Along the road we found the first of several Gladiolus sericeovillosus and a little further on, Gloriosa modesta.

As we drove towards Mark's Dam on the forestry roads, we saw the first of the Midlands endemics for the day -- Dierama luteoalbidum, an impressively large-flowered species with off-white flowers. The grassland around the dam produced a good display of flowers, including the eyecatching Leobordea corymbosa.

We explored the rocky ridges above the dam and fortunately Isabel was able to direct us to find some of the special species of this area. Passing some Crocosmia potsii and a few Zaluzianskya microsiphon, we came across a large flowered Indigofera  species and Wahlenbergia appressifolia.

In the wetter areas near the stream we found a few Psoralea rhizotoma in flower.  Crossing a drainage line and up the next slope we started seeing clumps of the Endangered endemic Aloe neilcrouchii as well as small clumps of Delosperma sutherlandii, both new species for us. In between the rocks there were Dianthus zeyheri.

On top of the ridge we found Syncolostemon parviflorus - most of these plants had finished flowering but I managed to find one with a few flowers. There were also several Xysmalobium parviflorum hunched against rocks and a patch of the tall-stemmed Gerbera kraussii.

We then drove to the top of Mount Gilboa and immediately started seeing many orchids, the most prominent of which, and possibly the dominant species on this peak, was Disa pulchra. Close to the vehicle we found a Disperis cardiophora, some Drimia sphaerocephala and one or two of the shy, small-flowered Moraea trifida as well as Zaluzianskya natalensis.

We had a great time wandering among the Disa pulchra and Disa chrysostachya, finding a Teedia lucida growing between two big rocks. We stopped to examine a clump of pink Dierama and decided these were Dierama dracomontana

After a quick lunch looking out over the flowering Calodendrum capense trees in the indigenous forest below us, we decided to explore another nearby peak and scaled a fairly steep grassy slope to get to the top. We saw many Athrixia arachnoidea and then came across Disa saxicola in the long grass. Growing in rock crevices we found several Begonia sutherlandii proudly showing their bright orange flowers, contrasting with the white flowers of the little Streptocarpus pusilus.

Back at the bottom of the hill there were Indigofera foliosa.

We have to thank Adam Shuttleworth for suggesting places to visit while we were staying in Hilton and what we might expect to see at these two sites. He also provided identification for two of the Apocynaceae we had not seen very often before.

A beautiful day at Ngele (Thursday 21 December 2017)

Having heard that the flowers were good at Ngele, we decided to make an early start and head up there to visit some grasslands. Once again we had a big group with us - on this occasion, last weeks' walkers were joined by Elaine Goodman, and we picked up Robertson Madwe, our regular guide at Ngele, once we arrived.

Our objective for the day was to explore grasslands in the Umsilo Hut area but to stop at any promising-looking patches along the way. Our first stop was at Ntunta next to the surfaced road between the lodge and Weza. Here we found, amongst others, Asclepias cultriformis, Cyphia elata and Adhatoda andromeda. After walking around here for some time we realised that we had missed the peak flowering for this patch by some weeks.

Heading on and up, we stopped at another grassland below Umsilo where we had found it to be very productive in the past. Massed flowering of Eriosema distinctum at the roadside greeted us as we got out of the vehicles and moved up the slope. Another eye-catching species was Watsonia lepida - Disa pulchra mimics this species so we had to look at each one to confirm what it was but unfortunately we were to find no Disa pulchra on this outingNear the top of this hill we started finding less common flowers. One of the first to catch the eye was Resnova lachenalioides (Ledebouria lachenalioides) but not far away was a single Gladiolus parvulus and the cryptically marked Gladiolus ecklonis.

Then we started to find several different members of the Apocynaceae family. First we found Aspidoglossum glanduliferum and soon after, Asclepias vicaria. Nearby was an Aspidonepsis flava.

Moving back down the hill we crossed the track and headed down the valley, skirting a small stream. Here we found plants enjoying wet conditions - Geranium subglabrum, Arctotis arctotioides, and a number of old inflorescence stems of Drimia macrocentra. The latter is an odd plant with tapering cylindrical leaves that often can emerge metres away from where the flower stalk appears.

Following this stream downwards, we reached a confluence with another small stream. In the flood plain between the streams there was a good population of bright pink flowered Chironia krebsii. In the wet soil at the edge of the stream we found a number of buds on Eucomis comosa var. striata and these were accompanied by several Barberetta aurea - a little unusual to find this shade-loving plant out in the open. Also at the side of the stream were several Bowkeria verticillata. A short distance upstream we found a single Eulophia parvilabris. Growing in the path were Hypoxis parvula var. albiflora and dotted around this area were Helichrysum cooperii.

Climbing back out of the valley we encountered Cycnium racemosum and Indigastrum fastigiatum. On a rock outcrop was a Xysmalobium tysonianum. Back near the vehicles we found a lonely Disa stachyoides.

We drove a little further and stopped in the shade of some pine trees to enjoy our lunch to the sound of a nearby stream. We filled our water bottles with this clear mountain water and then strolled across the section of grassland just below where the Umsilo overnight hut was situated. There were some serious cattle paths across this grassland - cattle grazing in the nature reserve is a contentious issue and needs resolution before the grasslands are irreparably damaged. A balance needs to be found between pressure to allow grazing by the local community's cattle and the need for conserving the biodiversity of this very valuable montane area.

In this area we found the brown-maroon flowered Schizoglossum stenoglossum with another plant nearby full of softly furry fruits.

On a south-facing bank we found several Tulbaghia leucantha and what is probably Ledebouria cooperii. Apart from Pachycarpus concolor, we also found Pachycarpus plicatus. Hidden in cracks in rock outcrops were several flowering Streptocarpus pusilus.

Walking back we found an enormous mushroom - what is locally known as iKowe, and is renowned to be very good eating. Unfortunately this one had sat out too long and the gills were infested with maggots.

We posed here for our group photo with the Ngele mountain range in the background.





After dropping Robertson off at the DAFF offices, we drove a different route to allow us a little time to explore a final grassland. Here we did particularly well first finding Eucomis comosa var. striata in flower and then seeing Satyrium parviflorum. We were also lucky to find Dioscorea brownii in flower and could make a voucher specimen as this was one of our target species.

In a little wet area we found many beautiful"Christmas Bells", Sandersonia aurantiaca, as well as tall Ornithogalum princeps, and as we did a final sweep through the grassland on our way back to the vehicles, we found Xysmalobium undulatum and Sisyranthus trichostomus.
