Justification
This species is widespread and very common. Although there are ongoing threats to coastal subpopulations, it is not yet in danger of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape, Western Cape
Range
It is widespread across the mountains and coastal plains of the southern Cape, where it occurs from the Riviersonderend Mountains in the Western Cape, to Kouga Mountains in the Eastern Cape, and on the coastal plains from Potberg to Tsitsikamma.

Description
This species occurs in sandy soils in montane and lowland fynbos, often at forest margins, 0-1700 m. Mature individuals are killed by fires, and only seeds survive. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is dioecious, with insect-pollinated male and female flowers occurring on separate plants.
Threats
About 16% of this species' habitat is already irreversibly modified, predominantly due to loss to coastal development and timber plantations. Habitat loss continues, causing slow, sporadic decline. Climate change and habitat loss modelling predicted that this species could decline by at least 30% by 2020 (Bomhard et al. 2005), but such drastic population reductions has not yet occurred. Recent field observations indicate that alien invasive plants are spreading into this species' habitat in the Outeniqua and Tsitsikamma mountains. Parts of the coastal plain between Potberg and Tsitsikamma is also densely infested with alien invasive plants that are outcompeting native species.
Population

Across its range, this species is abundant, frequently encountered in dense and extensive stands (Rebelo 2001).
