Description

Hibbertia praestans is a small, much-branched, broom-like shrub that typically grows to a height of 1.5–2 m (4 ft 11 in – 6 ft 7 in) and has pendulous, often flattened branchlets. The flowers are arranged singly or in pairs in leaf axils, with up to three narrowly club-shaped bracts 3.5–17 mm (0.14–0.67 in) long at the base. The five sepals are joined at the base with two lobes 2.5–3.0 mm (0.098–0.118 in) long and three that are 3.2–5.0 mm (0.13–0.20 in) long. The five petals are elliptic, red, and 3–4 mm (0.12–0.16 in) long and each flower has four stamens and a single carpel. Flowering occurs from December to August.[2]

Taxonomy

This species of Hibbertia was first formally described in 1992 by Lyndley Craven and Clyde Robert Dunlop who gave it the name Pachynema praestans in Australian Systematic Botany, from specimens Craven collected near Jabiru in 1973.[3] In 2009, James W. Horn changed the name to Hibbertia praestans.[4] The specific epithet (praestans) means "pre-eminent" or "superior".[5]

Distribution and habitat

This hibbertia grows in sandstone crevices or in open forest on scree slopes in northern parts of the Northern Territory.[2]

Conservation status

Hibbertia praestans is classified as of "least concern" under the Territory Parks and Wildlife Conservation Act 1976.[2]
