Description

Bertya rosmarinifolia is a bushy shrub to 3 m (9.8 ft) high and covered with short, matted hairs, sometimes becoming smooth. The leaves are linear-shaped, 10–25 mm (0.39–0.98 in) long, usually 0.5–1.5 mm (0.020–0.059 in) wide and the lower surface with whitish short, matted hairs. The flowers are usually borne singly, small, peduncles 1–2 mm (0.039–0.079 in) long, usually six small bracts, thickened and almost equal in size with whitish hairs. Flowering occurs from December to January and the fruit is an ovoid capsule 4–6 mm (0.16–0.24 in) long and occasional woolly hairs at maturity.[2]
