Revision of the Tarchonanthus camphoratus complex (Asteraceae-Tarchonantheae) in southern Africa

Abstract

The Tarchonanthus camphoratus L. complex in southern Africa is revised. Five species are recognized on the grounds of differences in synflorescences, fowering times, leaf shape and margin, and distribution. Two names, T. minor Less. and T. obovatus DC., are resurrected and two new species, T. littoralis P.P.J.Herman and T. parvicapitulatus P.P.J.Herman, are described. A key, full descriptions of each taxon and distribution data are presented.
