The plant takes the form of a prostrate shrub.[6] The main stem is subterranean.[8] It grows up to 80 centimetres (31 in) in diameter.[6] The above-ground branches are up to over 3 inches (7.6 cm) long, glabrous, prostrate, sometimes ascending.[8]
It has forms with narrow leaves, as well as forms possessing much broader leaves.[5]
It blooms in late Spring,[5] from September to February, with the peak from September to November. The plant is monoecious with both sexes in each flower. The seed is stored in a capsule within the woody, dried inflorescence, which is itself retained on the shrub after it is dead ('persistent'). The seeds are usually released one to two years after flowering and dispersed through by means of the wind.[6]
Pollination occurs through the action of rats, mice and birds. The plant grows in dry, rocky, mountain ledges at altitudes of 1000 to 1800 metres. Potential wildfires destroy the adult plants, but the seeds are able to survive such events.[6]
Conservation
It is rare, and usually found as solitary individuals or in isolated, small groups of less than two dozen plants.[6] The population numbers are thought to be stable.[4]
