Description | It occurs on hot, dry, north-facing slopes at the fynbos-karoo ecotone, 450-1200 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 pollinated by rodents. |
Threats |
| This species has lost a small proportion (6%) of its habitat to crop fields in the past. Its habitat is however only marginally suited to cultivation, and therefore it is not a significant ongoing threat. |
Population |
This is a social species and grows in dense stands. Very few subpopulations are small. The population is currently stable.
