Description
Angianthus brachypappus is an erect or low-lying, hairy, annual herb that typically grows to a height of 5–13.5 cm (2.0–5.3 in), usually forming branches at the base and/or near the top of plants. The leaves are hairy, lance-shaped with the narrower end towards the base, sometimes narrowly elliptic to more or less linear, 10–30 mm (0.39–1.18 in) long and 1–5 mm (0.039–0.197 in) wide. The flowers are borne in oval or elliptic compound heads of 100–300 pseudanthia, the heads 10–25 mm (0.39–0.98 in) long and 5–8 mm (0.20–0.31 in) wide. Flowering occurs from September to December, and the achenes are oval, 0.5–0.8 mm (0.020–0.031 in) long and about 0.8–1.3 mm (0.031–0.051 in) wide, the pappus often with 1 or 2 bristles.[2][3][4]
