Fossicking in the cliff-edge forests at Cubica Heights (Thursday 15 March 2018)

With the publication of the name of the new species of Hesperantha which we found last year expected soon, we decided to head the Cubica Heights to see if any had emerged yet. Before we went to the Hesperantha site however we first went to look at the Outeniqua Falls. Luckily, it was overcast and this made it easier to take photos of what is normally a very contrasty scene. On the way to the waterfall we found Gladiolus eckloniiMonsonia praemorsa and a big patch of Monocymbium ceresiforme.

Looking in the opposite direction we could see a bright pink swathe of Watsonia densiflora. At the first rock outcrop where the grassland drops down into the Outeniqua gorge, the Loxostylis alata were showing the full range of colour from white flowers to red bracts and combinations of both. A nearby Phylica paniculata was also starting to flower and in their shade there were several clumps of Aeollanthus parvifolius. Unexpectedly early (or late) was a few clusters of flowers on Pseudoscolopia polyantha. 

Needing a careful look to distinguish the similar looking flowers from the Aeollanthus we found some Brownleea coerulea growing in the leaf litter.

We walked across another rocky promontory, passing spikes of purple-flowered Plectranthus hadiensis, until we reached a forested edge to the cliffs. We found our way into this narrow patch of forest to be greeted by a showcase of Brownleea coerulea, Streptocarpus formosus and Stenoglottis fimbriata. There was a cluster of Rhipsalis baccifera bearing deep pink fruits. We also found the as yet undescribed species of Clutia in flower.

We enjoyed this spectacle for a while, venturing down the steep slope as far as we could before climbing out of the forest again.

Once back in the grassland we skirted the top of the forest for a while, finding Brachylaena glabra, Olea capensis subsp. enervis, Tarchonanthus trilobus and Cassipourea gummiflua flowering and Viscum obscurum in fruit. A little further on there was a great mass of Pelargonium capitatum climbing over other shrubs, as was a Dolichos sericeus.

We then found an unusually floriferous Indigofera herrstreyi (ined.), while below us and impossibly out of reach was a Rhynchocalyx lawsonoides covered in white flowers.

We then found another access into the forest and a couple of us pushed our way down the slope. It seemed to be more of the same - apart from two young Celtis gomphophylla - until Gail spotted a Begonia flowering below us. This turned out to be an Endangered Begonia homonyma, a plant not often seen in the Umtamvuna NR.

Growing on a steep rock face was Oplismenus hirtellus, a forest floor grass species, sporting two flower stalks and lower down on the same rock was Oldenlandia tenella.

By now the troops were clamouring for lunch so we moved more quickly around the forest to a great view spot.

We checked for the Hesperantha but there was no sign of them yet. Heading back to the vehicle, we came across more pink-flowered Craterostigma sp. nov.,  scattered among white flowered plants. A little further on we saw a small frog poorly camouflaged against the bright pink of a Watsonia densiflora.

As we reached the entrance to Beacon Hill we noticed a Brunsvigia grandiflora  and this was accompanied by numbers of Syncolostemon ramulosus. We had timed things just right -- we had enjoyed the cool, overcast conditions all day and as everyone departed it started to rain.
