Description
Pimelea leucantha is an erect shrub that typically grows to a height of 0.4–2 m (1 ft 4 in – 6 ft 7 in) and has a single stem at ground level. The leaves are mostly linear to narrowly egg-shaped or narrowly elliptic, 12–28 mm (0.47–1.10 in) long and 1–5 mm (0.039–0.197 in) wide on a petiole 0.5–1.2 mm (0.020–0.047 in) long. The flowers are white to pale yellow and arranged in clusters on a peduncle 1–6 mm (0.039–0.236 in) long. There are 4 or 6 pale yellowish green, often pink-tinged, egg-shaped involucral bracts 14–24 mm (0.55–0.94 in) long and 6–14 mm (0.24–0.55 in) wide around the flower clusters, each flower on a hairy pedicel 1.0–1.5 mm (0.039–0.059 in) long. The sepals are 3.0–5.5 mm (0.12–0.22 in) long, the narrow section of the floral tube 9–14 mm (0.35–0.55 in) long, and the stamens usually shorter than the sepals. Flowering occurs from August to early November.[2][3][4][5]
