These plants are either tufted or forming long runners.
The trigonous leaves are 3-6.5 cm long and their margins and keel have tiny teeth near the tip.
In June-July the flowers appear; they are solitary, about 3 cm in diameter, on 2-4 cm long stalks; the petals are pink to white with pinkish-purple central vein and sides.
As in the other two species in the genus (see also B. intrusa), the flowers turn into almost globular tumble fruits, lying on the ground and facing upwards.
The plants occur on stony slopes in the area between McGregor, Swellendam and Montagu.
Since its description as a Mesembryanthemum in 1920, the species has been placed in Erepsia, Ruschia, Acrodon and Cerochlamys.
If you are interested in the vagaries of its taxonomic history, search the Web for “A Gordion knot in Ruschioideae (Aizoaceae): Acrodon and Brianhuntleya in an attempt to disentangle the confusion” by Heidrun Hartmann and Ingeborg Niesler in Bradleya 30/2012, p. 33-60.
