Justification | Endemic to a small area on the southern slopes of the Outeniqua Mountains (EOO < 100 km²), known from four historical subpopulations, one of which was destroyed by afforestation. The three remaining subpopulations are all very small (average 20 plants) and there are fewer than 200 plants in total. A decline in habitat quality is occurring due to alien plant invasion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |

Description | Moist fynbos on sandstone slopes. |
Threats |
Afforestation: severe past threat to one of the four known subpopulations which is now lost. The remaining 3 subpopulations have lost significant habitat to plantations
Invasive plants: All three remaining known subpopulations are small fragments between forestry areas and are being severely invaded by woody acacias and herbaceous aliens. |
Population |
Three remnant populations remain- all of which are very small - less than 200 plants left.
