Description

Pimelea preissii is an erect, spreading shrub that typically grows to a height of 8–70 cm (3.1–27.6 in) and has glabrous stems. The leaves are arranged in opposite pairs, glabrous and narrowly elliptic, 5–20 mm (0.20–0.79 in) long and 2–7 mm (0.079–0.276 in) wide on a short petiole. The flowers are arranged in compact clusters of many white or pink flowers, surrounded by 4 green involucral bracts 6–14 mm (0.24–0.55 in) long and 4–10 mm (0.16–0.39 in) wide. The flower tube is 10–16 mm (0.39–0.63 in) long and the sepals 3–5 mm (0.12–0.20 in) long, the stamens shorter than the sepals. Flowering occurs from September to December.[2][3]

Taxonomy

Pimelea preissii was first formally described in 1845 by Carl Meissner in Lehmann's Plantae Preissianae.[4][5] The specific epithet (preissii) honours Ludwig Preiss.[6]

Distribution and habitat

This pimelea mainly grows in woodland and forest between Wooroloo, Cape Leeuwin and the Bow River in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren bioregions of south-western Western Australia.[2][3]
