Scientific Name | Oxalis burtoniae T.M.Salter |
Higher Classification | Dicotyledons |
Family | OXALIDACEAE |
National Status |
Status and Criteria | Vulnerable C1+2a(i) |
Assessment Date | 2012/10/25 |
Assessor(s) | N.A. Helme |
Justification | EOO, AOO <472 km², habitat at between 10 and 15 locations continue to decline due to coastal development. We suspect at least 10% of the population has been lost over the past 10 years. The majority of subpopulations known (80%) have been surveyed by volunteers of the Custodians of Rare and Endangered Wildflowers (CREW) Programme, indicating that subpopulations are always smaller than 1000 individuals and the total population is <10 0000. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Paternoster to Saldanha Bay. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Saldanha Limestone Strandveld, Saldanha Granite Strandveld |
Description | Granite and limestone outcrops, 0-100 m. |
Threats |
| Urban and coastal development is causing ongoing habitat loss, causing around 10% population decline since 2009. This species is likely to be overlooked in Environmental Impact Assessments as it has a very short flowering season. |
Population |
Most surveyed subpopulations are small, consisting of 50 to 250 plants, with only one subpopulation of 500 plants recorded.

Population trend | Decreasing |
