Cheiridopsis

Cheiridopsis is a genus that consists of 100 species of flowering succulent perennial plants, native to semi-arid regions in the far west of Namibia and South Africa.
Description.
Most species are clump-forming, a few are shrubby. The leaves are opposite and triangular in section, rarely flattened, the surface more or less velvety, which makes them easy to distinguish from species of the allied genus "Argyroderma". Daisy-like flowers open during the day in summer, are borne singly and usually have yellow, rarely purple or red, petals.
The name comes from the Greek "cheiris", meaning "sleeve". Each succeeding pair of leaves differs from the previous one in form, size, and relative unity of the leaves. Those most united wither in the resting period and form a papery sheath covering the succeeding pair of leaves during dormancy in dry, hot summer.
Distribution.
The genus occurs in the far west of South Africa and Namibia. Here it occurs from the Western Cape Province northwards through the Namaqualand, into Namibia.
Cultivation.
The species are mostly adapted to a very arid, winter-rainfall climate. The tender species "C. peculiaris" requires cultivation under glass in temperate regions.
