Description
editGoodenia willisiana is an erect or ascending perennial herb up to 20 cm (7.9 in) tall with its foliage covered with white, felt-like hairs. The leaves are crowded at the base of the plant, narrow elliptic to lance-shaped, 40–90 mm (1.6–3.5 in) long and 4–18 mm (0.16–0.71 in) wide, sometimes with wavy edges. The flowers are arranged singly in leaf axils on a stalk up to 100 mm (3.9 in) long with linear bracteoles about 2 mm (0.079 in) long. The sepals are narrow oblong, about 3.5 mm (0.14 in) long, the petals yellow and about 15 mm (0.59 in) long. The lower lobes of the corolla are 5–6 mm (0.20–0.24 in) long with wings about 2.5 mm (0.098 in) wide. Flowering mainly occurs from August to February and the fruit is an oval capsule about 10 mm (0.39 in) long.[2][3][4][5]
Taxonomy and naming
editGoodenia willisiana was first formally described in 1990 by Roger Charles Carolin in the journal Telopea from material collected by James Hamlyn Willis near Redcliffs in 1937.[6] The specific epithet (willisiana) honours J.H. Willis.[5]
Distribution and habitat
editThis goodenia grows in western New South Wales, north-western Victoria and south-eastern South Australia, often on sandhills and in mallee communities.[2][3][4][5]
