A revision of Tecophilaeaceae subfam. Tecophilaeoideae in Africa

Abstract

Family Tecophilaeaceae subfam. Tecophilaeoideae is revised for the Flora of southern Africa region, with the inclusion of the tropical Walleria mackenzii J.Kirk for completeness. The genera Cyanella Royen ex L. (9 spp.), Eremiolirion J.C.Manning F.Forest (1 sp.) and Walleria J.Kirk (3 spp.) are treated, with keys to the genera, species and subspecies; and full descriptions and distribution maps. A formal infrageneric classification is proposed for Cyanella, in which sect. Trigella (Salisb.) Pax K.Hoffm. is revived for the species with a 3 + 3 arrangement of stamens. The new species, C. marlothii J.C.Manning Goldblatt, is described from the Richtersveld; and C. pentheri Zahlbr. is resuscitated from the synonomy of C. hyacinthioides Royen ex L. Pink-flowered plants of normally yellow-flowered C. lutea have a separate geographical distribution and are recognized as subsp. rosea (Eckl. ex Baker) J.C.Manning Goldblatt.
