Stapelia grandiflora var. grandiflora

Because they may form large clumps to over a meter in diameter, plants of this species are often quite conspicuous in the field. They occur widespread in the Great Karoo and from Calitzdorp to the Eastern Cape and into the Free State, usually among bushes on lower stony slopes or under trees on flats.
The stems are up to 30 cm long. As the name implies, the flowers are often quite big too (mostly 8-15 cm, but sometimes up to 22 cm in diameter); they are usually silky hairy and appear mainly from March through May. The buds are rounded, which is typical for this variety (see last picture, showing a plant in cultivation).
The first 3 pictures were made near the Calitzdorp Dam, 6 April 2010.

Hoodia (Trichocaulon) flava

Although these plants may reach a height of 50 cm, they are usually much smaller.
They occur in a few places in southern Namibia and around Pofaddder in Bushmanland, but the majority of them are found from Calvinia to Carnavon in the central Great Karoo and southwards as far as Prince Albert and Rietbron. They often grow inside bushes, especially those of spiny Ruschias.
The plants in habitat were photographed south of Pofadder, the other ones in cultivation.

Tridentea gemmiflora

Clumps of this species may become more than a meter in diameter. It is widespread on flats in dry scrub from Worcester to the Free State, but it is never common.
The beautiful and distinctive flowers are 4.5-10 cm across and appear from March to May. Usually they are deep brown to purple black with yellowish mottling, but sometimes the yellow spots are so dense that the colour pattern is almost reversed.

Quaqua mammillaris 1

I find it quite difficult to make a good picture of the flowers of this species. They are so dark that they seem to absorb all the available light and turn black in the picture. Under an overcast sky, with enough light but no sun, one can see that the flowers in fact are a beautiful very dark purple. The flowers appear in autumn and winter (March-June).
The species has the widest distribution of the whole genus -from Namibia to the Little Karoo. The plants are few and far in between, growing on stony flats and slopes; they may become up to 60 cm tall.

Orbea verrucosa

According to the literature, this species occurs from just west of Oudtshoorn in the Western Cape to the Kei River in the Eastern Cape.
The pictures shown here however, were taken not fear east of Ladismith, extending the known distribution area 70-80 km westwards. The plants grow here in one of their typical habitats: on dry stony slopes among small bushes.
When you have a close look at the first two pictures, you will see that they are almost identical – but one is taken with ambient light and the other with flash. Can you see which is which and do you have a preference?

Quaqua ramosa

Over the years I came across several plants of this species, but although it is not uncommon in the Little Karoo and just north of it in the southwestern Great Karoo, I had never seen a flowering plant in the wild.

Near Ladismith, 1 May 2011

Last Friday I met a new plant friend, who lives near Montagu. She showed me around on her farm  where there were several plants of this species with its unusual stems. And, lo and behold, one of them was in flower. This was even more remarkable because the literature tells us that the flowers occur from March to May. Quite a nice birthday present!
