Cephalophyllum is a genus of plants fromthe afternoon flower family (Aizoaceae). The botanical name is derived from the Greek words cephalotes for head and phyllo for leaf.

description

The species of the genus Cephalophyllum grow compact, are creeping and only rarely upright. They make pillows. Their almost free, light to dark green leaves are triangular, spindle-shaped, keel-shaped or club-shaped. The keel is often crooked and the sides very different. Your epidermal cells are more or less flat. There is crystal sand in them. The horizontal wax platelets form a thick, continuous layer. The stomata are hardly sunk.

The flowers appear in fairly large groups. The five to six sepals are similar. Their petals can be white, yellow, pink to purple, red, copper or orange. Filamentous staminodes are only present in one species.

The five- to six-pod, funnel-shaped or convex capsule fruits remain on the plants. The closure bodies are large, the valve wings wide. The fruits contain brown, pear-shaped seeds that are 0.75 to 0.85 millimeters long and 0.55 to 0.65 millimeters wide.

Systematics and distribution

The genus Cephalophyllum is common in the center of the Western Cape province of South Africa. The species grow in crevices or in slate-rich places with an annual rainfall of 100 to 200 millimeters, which falls mainly in March and November.

The first description of the genus by Nicholas Edward Brown was published in 1928. The type species is Cephalophyllum tricolorum . The genus Cephalophyllum comprises two sub-genera with the following species:
