Habitat and Ecology
Major system
Major habitats
North Sonderend Sandstone Fynbos
Dry, stony north-facing slopes in sandstone fynbos, 500-1200 m. Mature individuals are killed by fires, and only seeds survive. Seeds are released after ripening, and collected by rodents and stored in underground caches, where they are protected from fires. It is dioecious, with insect-pollinated male and female flowers occurring on separate plants.
Although this species is confined mostly in a protected area, the biggest threat is the planting of protea orchards in its habitat. Hybridization of planted plants with native species and expansion of these fields is likely to be a threat. There are scattered hakea and pine plants that are likely to outcompete the indigenous species if left unmanaged.
