A review of generic concepts in the Stilbaceae

The generic concepts in the Cape endemic family Stilbaceae (+/- 14 species) , are reviewed. Proposals by various authors to include Retzia capenisis Th unb. in the Stilbaceae are supported. Xeroplana Briq. and Eurylobium Hochst . are shown to be congeneric with Stilbe L., resulting in one new combinati on and one new name in Stilbe. Seven currently recognised species of Stilbe are enumerated. A key to the genera of the Stilbaceae, as presently unders tood, is provided. A new genus Kogelbergia is described to accommodate two species previously assigned to Stilbe sect. Amphistilbe and two new combina tions in Kogelbergia are proposed.
