Pimelea brevistyla

Pimelea brevistyla is a shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in). The leaves are narrowly egg-shaped, 7–28 mm (0.28–1.10 in) long, 2.0–3.5 mm (0.079–0.138 in) wide and more or less sessile with the edges curved downwards. The flowers are white, and borne in head-like racemes surrounded by 2, 4 or 6 involucral bracts 8–22 mm (0.31–0.87 in) long, each flower on a hairy pedicel about 1 mm (0.039 in) long. The floral tube is 6–10 mm (0.24–0.39 in) long, the sepals white and spreading, 3–6 mm (0.12–0.24 in) long and hairy on the outside. Flowering occurs from August to October.^[2][3][4][5]

Pimelea brevistyla was first formally described in 1984 by Barbara Lynette Rye in the journal Nuytsia from specimens collected in Glen Forrest in 1983.^[6] The specific epithet (brevistyla) means "short style".^[2]

In a later edition of the journal Nuytsia, Rye described two subspecies of P. brevistyla and the names are accepted by the Australian Plant Census:

• Pimelea brevistyla Rye subsp. brevistyla^[7] has involucral bracts 12–20 mm (0.47–0.79 in) long, the floral tube 11–15 mm (0.43–0.59 in) long and sepals 4.5–6 mm (0.18–0.24 in) long.^[5][8][9]
• Pimelea brevistyla subsp. minor Rye^[10] has involucral bracts 7–11 mm (0.28–0.43 in) long, the floral tube 8–11 mm (0.31–0.43 in) long and sepals 3–4 mm (0.12–0.16 in) long.^[5][11][12]
