Collected in 1801 and 1819 and last seen in 1933. Extensive searches in the 1960s and 1990s, the latter accompanied by a reward of R1000, have yielded no sign of the species. It is serotinous and unlikely to survive as seeds in soil-stored seedbanks. Cause of extinction is unknown, but is likely the result of habitat loss to crop cultivation, alien plant invasion and afforestation.

Habitat and Ecology
Major system
Major habitats
This species occurs in riverine and swampy areas. 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 dioecious, with wind-pollinated male and female flowers occurring on separate plants.
Timber plantations, and agriculture have caused habitat loss at all the known locations. Plantations are no longer expanding within the known range of this species, but remaining habitat is often densely infested with alien invasive plants, especially near plantations, where escaping pine seedlings spread into adjacent fynbos. It has also been misidentified Passerina and easily overlooked in vegetation surveys and environmental impact assessments.
