Description

Asterolasia buckinghamii is a slender, erect shrub that typically grows to a height of 1.5–2 m (4 ft 11 in–6 ft 7 in) with its young branches covered with star-shaped hairs. The leaves are spatula-shaped to broadly egg-shaped with the narrower end towards the base, 4–15 mm (0.16–0.59 in) long and 3–7 mm (0.12–0.28 in) wide on a petiole 2–4 mm (0.079–0.157 in) long. The leaves are covered with star-shaped hairs, densely so on the lower surface and the upper surface has a longitudinal groove. The flowers are arranged singly or in groups of two or three in leaf axils or on the ends of branchlets, each flower on a pedicel up to 2 mm (0.079 in) long. The five petals are yellow, elliptical, 4–8 mm (0.16–0.31 in) long and covered with star-shaped, rust-coloured hairs on the back and there are ten stamens. Flowering occurs from October to November.[2][3][4]

Taxonomy

This species was first described in 1940 by William Blakely who gave it the name Phebalium buckinghamii and published the description in The Australian Naturalist.[5] The following year, Blakely changed the name to Asterolasia buckinghamii.[6] The specific epithet (buckinghamii) honours "Mr. William J. Buckingham of Lindfield, New South Wales".[4]

Distribution and habitat

Asterolasia buckinghamii grows in gullies and on river flats or on slopes near cliff tops. It occurs in the Wingello district and between Mittagong and Lithgow in New South Wales.[2][4]

gollark: I think this is a reasonable way to do copyright in general; some (much shorter than now!) length where you get exclusivity, which can be extended somewhat if you give the copyright office the source to release at the end of this perioid.
gollark: This isn't really "repair"y, inasmuch as you can't fix it if it breaks unless you happen to be really good at reverse engineering.
gollark: Maybe what you mean is banning DRM-ish things, so you can definitely copy the program and run it elsewhere and such?
gollark: Well, you can't actually run the program if you don't have... the program, DRM or no.
gollark: A lot of things now do the fourth.
