Abstract

A numerical taxonomic study of three genera of the Ruschiinae (Mesembryanthemaceae) is presented. Seven species are recognized in Astridia. Four species are recognized in Acrodon and two new combinations are made:A.  leptophyllus (L. Bol.) Glen and A. duplessiae (L. Bol.) Glen. Five species are recognized in Ebracteola and two new combinations are made:  E. wilmaniae (L. Bol.) Glen and  E. fulleri (L. Bol.) Glen. This study is largely based on the cited herbarium material, and the characters used are mainly the following: dimensions of plants, leaves and internodes, number and dimensions of parts of flower and fruit, colour of petals, and colour, dimensions and surface structure of seeds.
