Description

Asterolasia grandiflora is a weak, open shrub or sub-shrub that typically grows to a height of 20–60 cm (7.9–23.6 in). The leaves are oblong, elliptical or egg-shaped, 4–20 mm (0.16–0.79 in) long and 1.5–6 mm (0.059–0.236 in) wide on a short petiole. The upper surface of the leaves has star-shaped hairs when young but the lower surface is densely covered with star-shaped hairs. The flowers are arranged in three or four in leaf axils and on the ends of branchlets, each flower on a pedicel 5–17 mm (0.20–0.67 in) long and covered with thick, star-shaped hairs. The petals are pink to mauve, broadly elliptical to egg-shaped, 6–15 mm (0.24–0.59 in) long and 3–9 mm (0.12–0.35 in) wide, with thick-centred, star-shaped hairs on the back that formed a shield over the flower bud. There are between twelve and twenty-four stamens. [2] [3] [4]

Taxonomy

This species was first formally described in 1863 by William Jackson Hooker who gave it the name Phebalium grandiflorum and published the description in Icones Plantarum . [5] [6] In 1863, George Bentham changed the name to Asterolasia grandiflora, publishing the change in Flora Australiensis . [7] [8]

Distribution and habitat

Asterolasia grandiflora grows on breakaways and hills mostly between Toodyay and York in Western Australia. [2] [3]

Conservation status

Asterolasia grandiflora is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife, [2] meaning that is rare or near threatened. [9]
