Description

Persoonia cornifolia is an erect or spreading shrub with hairy young growth. The leaves are elliptic to egg-shaped, 20–80 mm (0.8–3 in) long, 10–45 mm (0.4–2 in) wide and flat with the edges more or less turned downwards. The leaves are hairy when young but become glabrous with age. The flowers are arranged in small groups in leaf axils with a scale leaf at the base of each flower. Each flower is on the end of a densely hairy pedicel 1–2 mm (0.04–0.08 in) long. The flower is composed of four hairy tepals 10–13 mm (0.4–0.5 in) long, which are fused at the base but with the tips rolled back. The central style is surrounded by four yellow anthers which are also joined at the base with the tips rolled back, so that it resembles a cross when viewed end-on. The ovary is usually hairy. Flowering occurs from December to February and is followed by fruit which are green drupes.[2][3]

Taxonomy and naming

Persoonia cornifolia was first formally described in 1830 by Robert Brown from an unpublished manuscript by Allan Cunningham. Brown's description was published in Supplementum primum Prodromi florae Novae Hollandiae.[4][5]

The specific epithet (cornifolia) is derived from the Latin words cornu meaning "horn"[6]:421 and folium meaning "leaf".[6]:340

Distribution and habitat

This persoonia grows in woodland and forest north from the Moonbi Range in north-eastern New South Wales and in south-eastern Queensland.[2][7]
