Stenanthemum tridentatum is a prostrate to upright, intricately-branched shrub that typically grows to a height of up to, its young stems sparsely covered with star-shaped hairs. The leaves are egg-shaped with the narrower end towards the base, to fan-shaped, long and wide on a petiole long, with stipules long and fused at the base. The flowers are creamy white or creamy-yellow and arranged singly, in pairs or three, wide, the floral tube about wide. The sepals are long, and the petals long. Flowering occurs in August, and the fruit is a more or less glabrous schizocarp long.[1]
This species was first formally described in 1845 by Ernst Gottlieb von Steudel who gave it the name Cryptandra tridentata in Lehmann's Plantae Preissianae.[2] [3] In 1858, Siegfried Reissek transferred it to Stenanthemum as Stenanthemum tridentatus in the journal Linnaea.[4]
Stenanthemum tridentatum grows in woodland and shrubland between Gunyidi and Tambellup in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Mallee bioregions of southwestern Western Australia.
