Abstract

For the first time since the genera were described, a taxonomic monograph of Lampranthus and its immediate allies was undertaken. A numerical study of 97 characters (132 character strings) of each of some 270 items was undertaken, using Hall's BOLAID package of numerical aids. The genus Lampranthus was reduced from about 240 species to 56. The genus Scopelogena was shown to be monotypic and closely related to Lampranthus. Braunsia was reduced from 5 species to 3. It is shown that the genera Oscularia and Esterhuysenia are inseparable from Lampranthus. Because Oscularia was described before Lampranthus, and because the latter is by far the better known, it is considered necessary to propose the conservation of Lampranthus over Oscularia. Such a proposal is included as an appendix. A new and more natural delimitation of the subtribe Lampranthinae, including Gibbaeinae and excluding the genera Cerochlamys, Disphyma and Ebracteola, is proposed.
