Justification | Albuca nana is known only from the type, collected more than 100 years ago at Redhouse, an area now extensively transformed due to urban and industrial expansion of Port Elizabeth. It is highly likely to be extinct, but surveys are still needed to confirm this. A large proportion of Albuca is still in need of revision, and this species has been overlooked and may have been misidentified in the past as it belongs to the section of Albuca not yet revised. In addition, a number of species known only from Port Elizabeth and previously thought extinct have recently been relocated around the city, and a small chance remains that this species could still be found. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Port Elizabeth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Albany Thicket |
Description | Unknown. |
Threats |
| The population is highly likely threatened and possibly close to extinction due to ongoing habitat loss to urban and industrial expansion, spreading informal settlements, and unmanaged alien invasive plants. |
Population |
Population trend | Stable |
Notes |
| Albuca nana belongs to a section of Albuca that has not yet been revised, and was overlooked in previous checklists (e.g. Germishuizen et al. 2006). It appears to be a distinctive species (M. MartÃnez-AzorÃn, unpublished notes). |
