Abstract

Faucaria Schwantes is a small genus of succulents, concentrated in south-central Eastern Cape. Distinguishing features of Faucaria are the characteristically dotted and toothed leaves and the structure of the seed capsule. A taxonomic review of the genus is presented, including relationship, diagnostic features, variation, distribution and ecology. The revision reduces the number of species from 33 to six:  F. bosschearui. F.felirui,  F. gratiae, F. nemorosa,  F. subintegra. and  F. tigrina. Two new subspecitic combinations,  F. felirtu subsp britteniae and  F. felina subsp tuberculosa have been made. A cladogram is included. A key to the taxa is provided and each species is described and illustrated.
