Andersonia macranthera is a low, compact, cushion-like shrub that typically grows to a height . Its leaves are pointed egg-shaped, long and wide with the ends curved backwards. The flowers are arranged with about ten to fifteen leaves and bracteoles on the flower stalk. The sepals are lance-shaped, mostly long and hairy. The petals are white, forming a tube shorter than the sepals, with lobes about the same length or shorter than the petal tube and bearded in the lower half. The stamens are about the same length as the petal tube, the anthers up to long but shorter than the filaments.[1]
Andersonia micrantha was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae from specimens he collected at King George Sound in 1801.[2] [3] The specific epithet (micrantha) means 'small-flowered'.[4]
This species of Andersonia grows in sand or sandy loam in the Esperance Plains, Jarrah Forest, Swan Coastal Plain, and Warren bioregions of southern Western Australia.
Andersonia micrantha is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
