Cheiridopsis velox
Cheiridopsis velox is a species of succulent plant from South Africa.

Description 
Cheiridopsis velox is a tangled succulent shrublet that grows to a heigh of  and a diameter of . The internodes are up to  long. Each branch bears between six and ten pairs of live triangular green leaves. They are about  long with a mild keel, whitish papillae and faint spots which are more or less continuous along the margins. They have sparse teeth near the tips which grow to a length of up to  and end in short, brown bristles. The old leaves remain on the branch and are pale brown in colour.

Flowers are present between late winter and mid spring, although they are most common in August and September. Each solitary flower is surrounded by leaf-like bracts. They are lightly scented, and open during the day and close at night. About 90-100 petals are present in two or three rows. They grow a length of  and are lemon yellow at the tip, fading to white at the base. They have five reddish sepals, three of which have translucent margins. They all bear a brown apical bristle. Each flower has about 18 stamens. The lemon yellow filaments are  long with dark yellow anthers. The dark green gynoecium has a diameter of  and has about 60 divisions. It is covered in granular idioblasts. There are eight to ten greenish stigmas. They are  long and covered in papillae.

The fruits are 8-10-locular, although 10-locular fruits are most common. They are  long. The fruits are plum red when young, becoming pale or dark brown over time. They are slightly convex above and rounded and papillate (covered in papillae) below. They do not have valve wings. The chestnut brown seeds ae pear shaped and  long.

Distribution and habitat 
This species is endemic to the Northern Cape of South Africa, where it is known from two localities. It grows in mountainous areas in the Richtersveld region, where is prefers quartzite plateaus. It grows on Ploegberg and Vandersterrberg.

Conservation 
The South African National Biodiversity Institute has classified Cheiridopsis velox as vulnerable. While it is not currently at risk of being trampled, it may be in the future as vegetation on lower slopes and nearer to settlements is used up by livestock, forcing them into the areas where this plant grows in search of food.
