Description
editStyphelia sieberi is an erect, densely-branched shrub that typically grows to a height of up to about 1 m (3 ft 3 in), and has softly-hairy branchlets. The leaves are oblong to more or less egg-shaped with the narrower end towards the base, 5.6–11.8 mm (0.22–0.46 in) long and 1.2–2.5 mm (0.047–0.098 in) wide on a petiole 0.3–0.6 mm (0.012–0.024 in) long. The edges of the leaves are finely toothed, there is a sharp point up to 1 mm (0.039 in) long on the tip, and the surfaces are more or less glabrous. The flowers are arranged singly in upper leaf axils on a peduncle about 1 mm (0.039 in) long, with bracteoles 1.3–1.7 mm (0.051–0.067 in) long at the base. The sepals are 2.8–4 mm (0.11–0.16 in) long, the petals white and joined at the base to form a tube 5.4–7.9 mm (0.21–0.31 in) long with lobes 1.9–2.9 mm (0.075–0.114 in) long. Flowering occurs from May to October and the fruit is a smooth, glabrous, oval to elliptic drupe 3.2–4 mm (0.13–0.16 in) long.[2][3][4]
Taxonomy
editThis species was first formally described in 1810 by Robert Brown who gave it the name Leucopogon juniperinus in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[5][6] In 2020, Michael Hislop, Darren Crayn and Caroline Puente-Lelievre transferred the species to Styphelia as S. sieberi in Australian Systematic Botany.[1] The name S. juniperina was not available, because it had already been given to a species, now known as Leptecophylla juniperina. The specific epithet (sieberi) honours Franz Sieber.[7]
Distribution and habitat
editPrickly beard-heath grows in forest and open shrubland on the coast and nearby tablelands of south-eastern Queensland, New South Wales and east of the Mitchell River in Victoria.[2][4][8]
