Asterolasia nivea, commonly known as Bindoon starbush,[2] is a species of weak sub-shrub that is endemic to the southwest of Western Australia. It has leathery oblong to narrow elliptical leaves and white flowers arranged in groups of about three flowers with thick-centred, shield like, star-shaped hairs on the back of the petals.
Description
Asterolasia nivea is a weak sub-shrub that typically grows to a height of about 50 cm (20 in). The leaves are narrow oblong, to elliptical, about 12 mm (0.47 in) long on a short petiole. The leaves are covered with star-shaped hairs. The flowers are arranged in groups of about three in leaf axils and on the ends of branchlets, each flower on a pedicel up to 15 mm (0.59 in) long and covered with thick-centred, star-shaped hairs. The petals are white, elliptical, 8–10 mm (0.31–0.39 in) long with thick-centred, star-shaped hairs on the back that formed a shield over the flower bud. There are between fifteen and twenty stamens.[2]
Taxonomy
This species was first formally described in 1980 by Paul Wilson who gave it the name Urocarpus niveus and published the description in the journal Nuytsia.[3] In 1987, Wilson changed the name to Asterolasia nivea, publishing the change in the journal Nuytsia.[4][5]
In 2017, Juliet A. Wege published a paper in Nuytsia suggesting that A. nivea is a white flowered form, and that the name A. nivea is a synonym of A. grandiflora. This change has been accepted by the Western Australian Herbarium but not as yet by the Australian Plant Census.[1][6][7]
Distribution and habitat
Asterolasia nivea grows in gravel between New Norcia and Bindoon in Western Australia.[2]
