Description

This shrublet grows tall. It has an alternate branching pattern and the herbaceous branches are sparsely hairy. The stalkless leaves are leathery and usually sparsely (rarely very) hairy. When sparsely hairy, the hairs are largely confined to the margins, the midvein and the tip of the leaf. They are oval shaped with a narrower end at the base. The sides may curve downwards (particularly in basal leaves) or upwards. Flowers are present between August and November and are borne in cymes, with the young buds arranged in two distinct rows. They are blue with conspicuous brown hairs at the tips of the sepals when they are young. The petals are dissimilar in length, with the two anterior lobes being larger than any of the other three petals. The outside of the flower is hairy. The stamens protrude past the petals in adult flowers. The staminal scales are ridge-like.

Conservation

This species is classified as endangered by the South African National Biodiversity Institute (SANBI). Despite its already restricted range, the population continues to decline as a result of agricultural expansion, development of holiday homes and the spread of invasive alien acacias.
