National Status |
Status and Criteria | Data Deficient - Insufficient Information |
Assessment Date | 2012/05/02 |
Assessor(s) | L. von Staden & M. MartÃnez-AzorÃn |
Justification | A poorly known species, first described in 1904 (Baker 1904). It has however been overlooked in checklists (Germishuizen et al. 2006, Manning et al. 2004) as it belongs to a section of the genus Albuca that has not yet been revised (Manning et al. 2009). It has a restricted range (EOO 7659 km²) and is known from only a few collections. It is however difficult to identify as a large proportion of the genus remains in need of revision, and may be doubtfully distinct from a number of other similar taxa. It is threatened by habitat loss to urban expansion in parts of its range, but overall transformation of the EOO is quite low (27%, calculated using GIS). The specific habitat requirements of this species is also not known, and at present not enough information is available to determine its risk of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Port Elizabeth to Grahamstown and East London. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Albany Thicket, Fynbos |
Description | Uncertain, possibly sandy soils in dry thicket and Acacia scrub, as well as grassy fynbos. |
Threats |
| Threatened by habitat loss to coastal and urban development around Port Elizabeth and East London. |
Population |
Population trend | Unknown |
Notes |
| Albuca longifolia is a very poorly known species and its description is very similar to a number of other South African Albuca species, but further study is needed to determine whether it is a valid species (M. MartÃnez-AzorÃn pers. comm. 2012). |
