Description

Hibbertia hirticalyx is an erect, spreading or low-lying shrub that typically grows to a height of 0.3–1.0 m (1 ft 0 in – 3 ft 3 in) and has hairy foliage. The leaves are narrow elliptic to narrow lance-shaped with the narrower end towards the base, 8–17 mm (0.31–0.67 in) long and 2–8 mm (0.079–0.315 in) wide on a petiole 0.4–1.4 mm (0.016–0.055 in) long. The edges of the leaves are turned down or rolled under. The flowers are arranged singly on the ends of the branchlets on a peduncle 2–8 mm (0.079–0.315 in) long, with a linear bract 3.0–4.4 mm (0.12–0.17 in) long. The five sepals are joined at the base, 3.2–6.2 mm (0.13–0.24 in) long and covered with star-shaped hairs. The five petals are bright yellow and wedge-shaped with a notch on the end, 6.0–9.6 mm (0.24–0.38 in) long. There are eight to twelve stamens arranged in a single cluster on one side of the two carpels, each carpel with four ovules. [2] [3]

Taxonomy

Hibbertia hirticalyx was first formally described in 1998 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected near Gladstone in Tasmania, in 1983. [2] [4] The specific epithet (hirticalyx) means "sepals with long, soft hairs". [2]

Distribution and habitat

This hibbertia grows in open forest in dry areas on Wilson's Promontory in Victoria, in the north of Tasmania and on the Bass Strait Islands. [2] [3]
