Scientific Name | Haworthia variegata L.Bolus |
Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Data Deficient - Taxonomically Problematic |
Assessment Date | 2014/03/24 |
Assessor(s) | L. von Staden, R.R. Klopper & J.C. Manning |
Justification | A taxonomically problematic species that is difficult to distinguish from other Haworthia species, particularly some forms of H. mirabilis, as well as the taxonomically problematic H. rossouwii. Until resolved, this species' risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Bredasdorp to Swellendam and Stilbaai. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Shallow soils in limestone outcrops and quartz patches overlying shale. |
Population |
Population trend | Unknown |
Notes |
Haworthia has been plagued with an overprolification of names, recognising variation over similarity, and causing much confusion (Bayer and Manning 2012). The genus needs to be revised using population-level molecular techniques in order for species concepts to be resolved (J.C. Manning pers. comm. 2014). |
