|
Scientific Name | Haworthia pygmaea Poelln. |
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 H. retusa, as well as H. mutica and some forms of H. emelyae. Until resolved, its risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Riversdale to Groot Brakrivier. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Rocky outcrops in coastal renosterveld and fynbos. |
Population |
Population trend | Decreasing |
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). |
