Scientific Name | Haworthia floribunda Poelln. |
Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Vulnerable C2a(i) |

Assessor(s) | J.H. Vlok, N.A. Helme, D. Raimondo & L. von Staden |
Justification | This species is known from fewer than 20 subpopulations, and the overall population numbers fewer than 10 000 individuals and no subpopulation has more than 1000 plants. It is declining due to collecting for the specialist succulent horticultural trade, road construction and livestock grazing. It has an extent of occurrence (EOO) of 1994 km², and is therefore listed as Vulnerable under criterion C. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to Overberg in South Africa, where it stretches from Heidelberg to Gourits River. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swellendam Silcrete Fynbos, Mossel Bay Shale Renosterveld, Eastern Ruens Shale Renosterveld, Ruens Silcrete Renosterveld, Cape Lowland Alluvial Vegetation |
Description | Plants grow in grassy, coastal fynbos. In renosterveld, plants are often found in well-shaded areas in microhabitats of moss and lichens. |
Threats |
| This species is threatened by habitat loss to crop cultivation, urban development and collecting for the specialist horticulture trade. One subpopulation has been degraded as the result of the construction of several roads. Holes where plants have been removed by collectors have been observed at one of the subpopulations. |
Population |
There are fewer than 20 remaining subpopulations, and all are small, numbering fewer than 1000 mature individuals. The population is estimated to number fewer than 10 000 mature individuals, and continues to decline.
