Studies in the genus Lotononis (Crotalarieae, Fabaceae). 9. Four new species of the L. pentaphylla group, section Lipozygis

Abstract

L. pentaphylla (E. Mey.) Benth. and related species were previously shown to be very different from the rest of the section Lipozygis (E. Mey.) Benth. of Lotononis (DC.) Eckl. & Zeyh. These species are all annuals and can easily be distinguished by their capitate inflorescences, sessile flowers and indehiscent, wind-dispersed pods. Four new species of this group are described, namely L oligocephala B-E. van Wyk, L globulosa B-E. van Wyk, L. laticeps B-E. van Wyk and L. longicephala B-E. van Wyk.
