TRANSFER OF THE SOUTHERN AFRICAN SPECIES OF LIGHTFOOTIA, NOM ILLEG, TO WAHLENBERGIA (CAMPANULACEAE, CAMPANULOIDEAE)

Lightfootia L'Her., validly published in January 1789, is illegitimate , being antedated by Light- footia Sw. (June-July 1788), and is furthe rmore a later synonym of Wahlenbergia as presently circumscribed. Wher eas the tropical African and Madagascan species formerly assigned to L ightfootia have already been named in Wahlenbergia, the 39 southern Af rican species currently recognized have not. New combinations or subst itute names are published here to rectify this situation. Two names, C ampanula sect. Campanopsis R. Br. and Lightfootia macrostachys A. DC., are typified.
