Description
editHibbertia pustulata is a small shrub that typically to a height of up to 15 cm (5.9 in) long and has more or less glabrous foliage. The leaves are more or less linear, mostly 6.0–7.5 mm (0.24–0.30 in) long, 0.6–0.8 mm (0.024–0.031 in) wide on a petiole 0.2–0.6 mm (0.0079–0.0236 in) long and with the edges rolled under. The flowers are arranged singly on the ends of branches with a triangular bract 0.7–1.1 mm (0.028–0.043 in) long at the base. The five sepals are joined at the base, the outer sepal lobes 5.9–6.3 mm (0.23–0.25 in) long and 2.5–2.6 mm (0.098–0.102 in) wide, the inner sepal lobes 3.2–3.4 mm (0.13–0.13 in) wide. The five petals are yellow, egg-shaped with the narrower end towards the base with a notch at the tip, 7.6–9.3 mm (0.30–0.37 in) long and there are four stamens fused at the base on one side of the two carpels, each carpel with four to six ovules. Flowering mainly occurs from August to October.[2][3]
Taxonomy
editHibbertia pustulata was first formally described in 2012 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected in Leura in 2006.[2][4] The specific epithet (pustulata) means "pustulate".[2]
Distribution and habitat
editThis hibbertia grows in swampy heathland near creek lines and occurs in the Blue Mountains and Wollemi National Parks in central eastern New South Wales.[2][3]
