Cleretum rourkei

A small succulent of the winter-rainfall Knersvlakte and southern Namaqualand, in a tribe made up of annuals. Grow it like other Cape winter annuals: sow in autumn, keep it cool and very bright through winter, and let it set seed and die back in the summer dry season.

Climate sites lie at about 140–550 m; few records carry an elevation.
