Description

Cheiridopsis inspersa - University of California Botanical Garden - DSC08879

Cheiridopsis species - Stellenbosch University Collection - RSA

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.
