Description
Pimelea brevifolia is an undershrub or shrub that typically grows to a height of 0.1–1 m (3.9 in – 3 ft 3.4 in). The leaves are erect, elliptic, 1–16 mm (0.039–0.630 in) long and 0.5–6 mm (0.020–0.236 in) wide and sessile or on a petiole up to 0.3 mm (0.012 in) long. The flowers are borne in heads on a peduncle mostly 5–20 mm (0.20–0.79 in) long and surrounded by four egg-shaped to broadly elliptic involucral bracts 4–12 mm (0.16–0.47 in) long and 3–9 mm (0.12–0.35 in) wide. The flowers are bisexual or female, usually white and glabrous inside, the floral tube 6–12 mm (0.24–0.47 in) long. The sepals are egg-shaped, 2–4 mm (0.079–0.157 in) long, the stamens shorter than the sepals and the style usually protrudes by up to 2 mm (0.079 in) long. Flowering occurs from July to October.[2][3][4]
Pimelea brevifolia R.Br. subsp. brevifolia[8] has egg-shaped involucral bracts and long hairs on the ovary part of the floral tube.[3][9][10]
Pimelea brevifolia subsp. modesta (Meisn.) Rye, previously known as Pimelea modesta Meisn.[11] has elliptic involucral bracts short hairs on the ovary part of the floral tube.[3][12][13]
