Justification | Brunia sphaerocephala is a rare and localized habitat specialist. It is known from four to five locations and potentially threatened by competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the mountains of the Western Cape, where it occurs in the Slanghoek, Wemmershoek and Hottentots Holland mountains. |

Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos, Hawequas Sandstone Fynbos |
Description | It is localized to upper sandstone slopes in mountain fynbos, typically above 1000 m. |
Threats |
| Alien invasive plants are spreading uncontrolled through parts of this species' range. If left unmanaged, they are likely to rapidly outcompete native species, increasing their risk of extinction. |
Population |
Brunia sphaerocephala is a sparsely distributed, localized habitat specialist. The population is not currently suspected to be declining, but it requires monitoring.
|
Population trend | Stable |
