Description

Micrantheum ericoides is a heath-like shrub that typically grows to a height of up to 70 cm (28 in), its new growth sometimes softly-hairy. The leaves are arranged in whorls of three, linear to narrowly elliptic, 4–10 mm (0.16–0.39 in) long and 1.0–1.5 mm (0.039–0.059 in) wide. The upper surface of the leaves is smooth, the lower surface covered with soft, white hairs. Male flowers are borne on a peduncle 1–2 mm (0.039–0.079 in) long, the tepals about 1.5 mm (0.059 in) long, and there are 3 stamens. Female flowers are on a peduncle that increases to 5 mm (0.20 in) long at the fruiting stage. Flowering occurs from August to November, and the fruit is a smooth capsule 6–7 mm (0.24–0.28 in) long and about 4 mm (0.16 in) wide.[2][3][4]
