Description

Boronia crassifolia is a slender, rounded shrub that grows to a height of about 30 cm (10 in). It has pinnate leaves with three, five or seven linear to spatula-shaped leaflets 5–10 mm (0.2–0.4 in). The flowers are yellowish green to brownish, about 10 mm (0.4 in) in diameter and hang from the leaf axils on a pedicel 3–5 mm (0.1–0.2 in) long. The four sepals are red, more or less round and about 2.5 mm (0.1 in) long. The four petals are about 4 mm (0.2 in) long. The eight stamens alternate in length with the four near the petals longer than those near the sepals.[2][3][4][5]

Taxonomy and naming

Boronia crassifolia was first formally described in 1845 by Friedrich Gottlieb Bartling and the description was published in Plantae Preissianae.[6][7] The specific epithet (crassifolia) is derived from the Latin words crassus meaning "thick", "fat" or "stout"[8]:237 and folium meaning "a leaf".[8]:466

Distribution and habitat

This boronia grows on sandplains and sand dunes, often among rocks near Mount Lesueur and from near Perth to the Stirling Range and east to the Twilight Cove, in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Hampton, Jarrah Forest and Mallee biogeographic regions.[2][3]
