Stenanthemum coronatum

Stenanthemum coronatum is a species of flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia. It is a prostrate shrub with sparsely hairy young stems, broadly egg-shaped leaves and densely shaggy-hairy heads of tube-shaped flowers.

Description
Stenanthemum coronatum is a prostrate shrub that typically grows to 2–5 cm high and 15 cm wide, its young stems sparsely covered with star-shaped hairs. Its leaves are broadly egg-shaped with the narrower end toards the base, 4–5 mm long and 3–4 mm wide on a petiole 1.0–1.5 mm long, with narrowly triangular stipules 2.0–3.5 mm long and fused together. There is a deep notch at the tip of the leaves with a sharp point on each side of the notch. The flowers are creamy-white and densely covered with shaggy white hairs, the floral tube about 3 mm long and 1.0–1.2 mm wide, the sepals 1.2–1.6 mm long and the petals about 0.8 mm long. Flowering occurs from September to November, and the fruit is 2.0–2.3 mm long.

Taxonomy and naming
This species was first formally described in 1848 by Siegfried Reissek who gave it the name Cryptandra coronata in Johann Georg Christian Lehmann's Plantae Preissianae. In 1858, Reissek changed the name to Stenanthemum coronatum in the journal Linnaea. The specific epithet (coronatum) means "crowned", referring to the leaf clusters on the ends of branches.

Distribution and habitat
Stenanthemum coronatum grows in woodland on laterite ridges between Bindoon and Narrogin in the Jarrah Forest bioregion of south-western Western Australia.
