The <i>Eriosema cordatum</i> Complex. I. The <i>Eriosema populifolium</i> Group

Abstract

The relationships among three species of Eriosema are discussed. E. distinctum N.E.Br. and E. populifolium Harv. are maintained as distinct from E. cordatum E. Mey. The relationships between these three species and extra-South African species of the E. cordatum complex are discussed in the light of new evidence.
