[3] The stamens are slightly dissimilar in length and the staminal scales are inserted well below the throat of the corolla tube, 3 mm (0.12 in) above the base.

[3] In present times, it is a highly restricted species and is known from one small sandstone outcrop on the Riversdale Plain.

The generation time is expected to be around 40 years, which is long for a species that lives in an ecosystem in which fire plays such a pivotal role.

[1] This species has been classified as critically endangered by the South African National Biodiversity Institute (SANBI).

[1] It grows best in well-drained sandy soil in warm, sunny areas, particularly on embankments and in rockeries.

Cuttings taken from the tips of branches do not root well and should instead be taken from the spindly side shoots re-sprouting from the older wood.

They should be pretreated with hot water and smoke to simulate fire in order to aid germination.
