Justification
EOO 634 km², AOO <20 km² this resprouting habitat specialist has been recorded from 10 subpopulations, it has lost habitat in the past to afforestation, crop cultivation, and infrastructure development. It is experiencing ongoing decline in habitat quality due to the spread of alien plants.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Lower slopes of Langeberg and Outeniqua Mountains.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Montagu Shale Renosterveld, Langkloof Shale Renosterveld, South Outeniqua Sandstone Fynbos, North Outeniqua Sandstone Fynbos, North Langeberg Sandstone Fynbos, Garden Route Shale Fynbos
Description
Transitional vegetation between renosterveld and dry, grassy fynbos, along disturbed roadsides or on lower slopes in dry, rocky, loamy or sandy soil.
Threats
Some habitat was lost in the past to timber plantations, and further expansion of plantations remains a potential threat. Habitat has also been lost to crop cultivation and road construction. This species is currently primarily threatened by the spread of alien invasive plants and possibly also by further expansion of crop cultivation on the northern slopes of the Langeberg.
Population

Subpopulations are typically small, consisting of around 50 plants. Only one large population of 200 individuals has been observed.
