It is a compact shrub with tiny leaves pressed against the stems and profuse heads of purple or pinkish-coloured flowers.

Beaufortia micrantha is a small, compact shrub which grows to a height of about 0.5 metres (2 ft).

The leaves are triangular in shape with the end tapering to a point, 1–2 millimetres (0.04–0.08 in) long and have their upper surfaces pressed against the stems, sometimes overlapping each other.

The leaves of Beaufortia empetrifolia are similar in size and shape but are not pressed against the stems to the same extent.

[8] Beaufortia micrantha is classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
