Ecology

Pollination occurs through the action of birds [3] [5] and beetles. [5] The seed is not stored in the woody fruit and is spread by the wind as soon as it is ripe. [3] [5] The plant grows in shallow sandstone soils or cracks in rock at altitudes of 500 - 1,500m. [5] It is long-lived and can re-sprout after burning from a bole-shaped rootstock, although it normally grows in areas where there is low risk of wildfires. [3] [5]

Distribution

This species is endemic to South Africa. [3] The plant is found in the Western Cape, on the Bokkeveld escarpment up to the Olifants River and the Koue Bokkeveld Mountains. [5] Here, it is a widespread and common species with no severe threats. [3]
