Description
Kennedia retrorsa is a vigorous climbing herb covered with rust-coloured or white hairs. The leaves are trifoliate with broadly elliptic to more or less circular leaflets 30–130 mm (1.2–5.1 in) long and 30–100 mm (1.2–3.9 in) wide with stipules about 5 mm (0.20 in) long at the base. The flowers are arranged in groups of four to twenty in racemes up to 250 mm (9.8 in) long on a peduncle 50–150 mm (2.0–5.9 in) long with lance-shaped bracts at the base. The sepals are 6–8 mm (0.24–0.31 in) long and the petals are pinkish-purple or scarlet and 12–15 mm (0.47–0.59 in) long, the standard petal more or less circular. Flowering mainly occurs from September to December and the fruit is a densely hairy, flattened pod about 60 mm (2.4 in) long.[3][4][5]
Taxonomy
Kennedia retrorsa was first formally described in 1907 by William Hemsley in Curtis's Botanical Magazine from specimens raised in Kew Gardens from seed "received from the Sydney Botanic Garden".[2][6] The specific epithet (retrorsa) means "pointing backwards".[7]
Distribution and habitat
This kennedia is only known from the Goulburn River National Park where it grows in cool, damp and rocky places in a range of habitats, usually in sandy soil.[4][5]
Conservation status
Kennedia retrorsa is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Government Biodiversity Conservation Act 2016.[4][5]
