Scientific Name | Hessea cinnamomea (L'Hér.) T.Durand & Schinz |
Higher Classification | Monocotyledons |
Family | AMARYLLIDACEAE |
Synonyms | Hessea crispa (Jacq.) Kunth, Periphanes cinnamomea (L'Hér.) F.M.Leight. |
National Status |
Status and Criteria | Endangered A2ac; B1ab(iii) |
Assessment Date | 2007/10/08 |
Assessor(s) | D.A. Snijman, J.E. Victor & D. Raimondo |
Justification | EOO 2400 km², over 50% of available habitat and known subpopulations have been lost to urban expansion on the Cape Flats over the past 140 years. This timeframe is less than three generations of this long-lived bulb species (generation length estimated to be 50 years). Ongoing habitat loss due to urban growth, crop cultivation and alien plant invasion continues to threaten the five remaining subpopulations. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Cape Peninsula, Riverlands and Joostenberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Peninsula Sandstone Fynbos, Hawequas Sandstone Fynbos, Boland Granite Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos |
Description | Fynbos, in seasonally waterlogged peaty lowlands. |
Threats |
| This species has lost extensive habitat to urban expansion and crop cultivation on the Cape Flats. Remaining subpopulations are confined to small fragments where they are threatened by ongoing habitat degradation as a result of alien plant invasion. Habitat loss to crop cultivation and urban expansion also continues. |
Population |
Population trend | Decreasing |
