Justification | Vexatorella amoena has a restricted distribution range in the Western Cape Province, South Africa, where it has an extent of occurrence (EOO) of 1791 km². It is however locally abundant. As there are no severe threats to this species, the population is assumed to be stable, and therefore it is not in danger of extinction and is listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs in the Koue Bokkeveld and Swartruggens mountains from Wuppertal to Karoopoort in the Western Cape Province, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Winterhoek Sandstone Fynbos, Cederberg Sandstone Fynbos, Swartruggens Quartzite Fynbos |
Description | It occurs on sandstone slopes in montane fynbos, 900-1800 m. Mature individuals are killed by fires, and only seeds survive. Seeds are released after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is pollinated by insects. |
Threats |
Field observations noted presence of alien invasive plants in some parts of this species' habitat. However, this is not considered a severe threat at present. |
Population |
This species is locally abundant, occurring as dense stands or as scattered plants. More than 50% of the subpopulations are small, each with less than 250 mature individuals. The largest subpopulation occurs on the Baviaansberg, with over 10 000 individuals. Although alien invasive plants are present in parts of the range, no significant population decline is suspected.
