Abstract
The present work was undertaken to provide a much needed taxonomic revision of the genus Astroloba Uitew. Type material of all previously described species appears to be completely lacking. This revision was based almost entirely on living material collected by the author. Studies were made of morphological variation, geographical distribution, cytology and ecology. The morphological studies were based on field population samples. As a result of these studies, seven species and three subspecies were established, of which three species and one subspecies are new : A. rugosa Roberts, A. hallii Roberts, A. smutsiana Roberts and A. foliolosa subsp. robusta Roberts. One new combination is made: A. foliolosa subsp. congesta (Salm-Dyk) Roberts. A new key to the species is given. Because this genus is so little known, a large number of plates are included. A new hybrid genus, X Astroworthia Roberts, was established for hybrids between the genera Astroloba and Haworthia Duval. This consists at present of one species, X Astroworthia bicarinata (Haworth) Roberts comb. nov.
