Range
Vryheid.
Habitat and Ecology
Major system
Terrestrial
Major habitats
KwaZulu-Natal Highland Thornveld
Description
Stony grassland, in well-drained, humus-rich soil on steep, broken granite slopes, 935 m.
Threats
When Erich van Wyk visited the population to collect seed for the Millennium Seed Bank project, he observed mature individuals that were dislodged from the cliff face where they grow and had fallen down into the riverbed. It is not known what had caused these plants to have become dislodged. According to the farmer, baboons like to eat the flowers and may have pushed over plants to reach the flowers. Monitoring of the population is required to determine whether this is causing an ongoing decline in the population.
