Other vernacular names for this plant are chestnut sugarbush, Clanwilliam protea or kayang bush. In Afrikaans it is known as the kaiingbos, kaiing-suikerbos, kaiinghout, kayangbos, kreupelwaboom or tolletjiewaboom.[3]
The tree's national number is 89.1.[6]
Description
editThe bush grows up to 5m high and has a conical shape. It blooms from July to November. The plant is monoecious with both sexes in each flower.[5]
Ecology
editPollination 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
editThis 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]
