Description edit
Hibbertia praemorsa is a shrub that typically grows to a height of up to 1.3 m (4 ft 3 in) with hairy foliage. The leaves are oblong, mostly 6.5–9.5 mm (0.26–0.37 in) long, 3.0–4.5 mm (0.12–0.18 in) wide on a petiole 0.2–0.4 mm (0.0079–0.0157 in) long and with a tuft of hairs on the tip. The flowers are arranged singly on the ends of branches with leaf-like bracts at the base. The five sepals are joined at the base, the outer sepal lobes 6.5–9.3 mm (0.26–0.37 in) long and 1.6–2.1 mm (0.063–0.083 in) wide and the inner sepal lobes shorter but broader. The five petals are yellow, broadly egg-shaped with the narrower end towards the base, 5.1–8.8 mm (0.20–0.35 in) long and there are seven to nine stamens fused together at the base on one side of the two carpels, each carpel with two ovules. Flowering mainly occurs from October to February.[2][3]
Taxonomy edit
Hibbertia patens was first formally described in 2010 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected in Morton National Park in 1999.[2][4] The specific epithet (praemorsa) means "bitten off", referring to the truncated ends of the leaves.[2]
Distribution and habitat edit
This hibbertia grows on steep, rocky slopes in Morton National Park, the Budawang Range and Bundanoon.[2][3]
