It is a low, compact shrub with linear to narrowly egg-shaped leaves and pink flowers in groups of three to six.

The pink, petal-like sepals are deep red at the base, and joined for most of their length, each with three to five hairy ribs, and covered with star-shaped hairs.

[4][5] In 1863, George Bentham transferred to species to Guichenotia as G. micrantha in Flora Australiensis.

[7] Small-flowered guichenotia grows on sand and laterite on sandplains, rocky hills and granite outcrops between Geraldton and Esperance, and as far inland as Eneabba and Southern Cross excluding the far south-west corner, in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australia.

[3][2] Guichenotia micrantha is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
