Description

Asterolasia buxifolia is a spindly shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in) with its stems covered with star-shaped hairs. The leaves are leathery and egg-shaped with the narrower end towards the base, 5–18 mm (0.20–0.71 in) long and 3–10 mm (0.12–0.39 in) wide on a petiole 2–7 mm (0.079–0.276 in) long. The upper surface of the leaves is glabrous but the lower surface is covered with star-shaped hairs. The flowers are arranged singly in leaf axils, each flower on a pedicel up to 1–1.5 mm (0.039–0.059 in) long. The five petals are yellow, elliptical, 6–7 mm (0.24–0.28 in) long and covered with star-shaped hairs on the back. [2] [3] [4]

Taxonomy

This species was first described in 1863 by George Bentham who published the description in Flora Australiensis . [5] [6]

Distribution and habitat

Asterolasia buxifolia is only known from a single site near the River Lett where it grows among granite rocks in forest in the Central Tablelands of eastern New South Wales. [2] [4] [7]

Conservation status

This plant was only rediscovered in 2000 and little is known about it. It is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016 . The main threats to the species include weed invasion, habitat disturbance and grazing by rabbits, hares and livestock. [7]
