Description edit

Hibbertia pedunculata is a diffuse, prostrate or erect shrub that typically grows to a height of up to 20–60 cm (7.9–23.6 in) and has wiry, hairy young branches. The leaves are linear, 3–6 mm (0.12–0.24 in) long and 0.5 mm (0.020 in) wide and sessile. The leaves are hairy and the edges turn downwards. The flowers are arranged singly on a peduncle 5–15 mm (0.20–0.59 in) long. The five sepals are joined at the base, the two outer sepal lobes 1.8–2.6 mm (0.071–0.102 in) wide and the inner lobes 2.8–3.3 mm (0.11–0.13 in) wide. The five petals are egg-shaped with the narrower end towards the base, yellow, up to 10 mm (0.39 in) long and there are fifteen to twenty stamens arranged in groups around the three hairy carpels, each carpel with four ovules.[3][4][5]

Taxonomy edit

Hibbertia pedunculata was first formally described in 1817 by Augustin Pyramus de Candolle in his Regni Vegetabilis Systema Naturale from an unpublished description by Robert Brown.[6][7] The specific epithet (pedunculata) means "pedunculate".[8]

Distribution and habitat edit

Stalked guinea-flower is widespread in eastern New South Wales where it grows in open forest.[4] Records from Victoria are now referrable to other species.[9]

Use in horticulture edit

This hibbertia is frequently grown in gardens and is hardy in a range of situations. It is easily grown from cuttings or possibly by layering.[10][11]
