|
Scientific Name | Haworthia emelyae Poelln. |
Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Data Deficient - Taxonomically Problematic |
Assessment Date | 2014/05/21 |
Assessor(s) | L. von Staden, R.R. Klopper & J.C. Manning |
Justification | Haworthia emelyae is difficult to distinguish from other species of Haworthia. The genus is in need of taxonomic revision, and until resolved, this species' risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Western Karoo, Klein Karoo to Uniondale. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Succulent Karoo |
Description | Karroid shrubland. |
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). |
