Justification
A range-restricted habitat specialist with an area of occupancy (AOO) of 20 km². It is known from three locations, and is potentially threatened by competition from alien invasive plants which are already present in low densities in some parts of its range. Should these invasives spread directly in the areas where this species' subpopulations occur, it would qualify for Endangered under criterion B. Given that this threat is currently still potential it qualifies for listing a Near Threatened under criterion D2.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
This species is restricted to the Riviersonderend Mountains in the Western Cape Province of South Africa.
Habitat and Ecology
Major system
Terrestrial
Major habitats
South Sonderend Sandstone Fynbos, North Sonderend Sandstone Fynbos
Description
It grows in rock crevices or rocky slopes at middle to high altitude.
Threats
Despite the existence of timber plantations and escaped pines on the lower southern slopes of Riviersonderend mountain, as well as widely dispersed invasive plants on the northern slopes, this species is found on middle to high slopes which have a relatively low density in invasive alien plants. The habitat also protects it from fires. Subpopulations are potentially vulnerable to future competition from alien invasive plants.
Population

Not much is known about this species' population, however it is not suspected to be declining.
