Description
editMicromyrtus stenocalyx is a straggly or widely spreading shrub that typically grows to a height of 0.8–1 m (2 ft 7 in – 3 ft 3 in). Its leaves are oblong or club-shaped and more or less pressed against the stem, 1.0–3.5 mm (0.039–0.138 in) long on a petiole about 0.3 mm (0.012 in) long with a few oil glands on the lower surface. The flowers are arranged singly in leaf axils and are 4–5 mm (0.16–0.20 in) long on a peduncle about 0.7 mm (0.028 in) long. The floral tube is cylindrical and about 3 mm (0.12 in) long, the sepals less than 0.3 mm (0.012 in) long and 0.5 mm (0.020 in) wide and the petals are cream-coloured to yellow, about 1 mm (0.039 in) long with several oil glands. Flowering has been recorded July to November.[2][3]
