Banksia corvijuga is a species of densely-foliaged shrub that is endemic to Western Australia. It has broadly linear, serrated leaves, heads of about sixty yellow flowers and glabrous follicles.
Banksia corvijuga is a densely-foliaged shrub that typically grows to a height of 1.3 m (4 ft 3 in) but does not form a lignotuber. It has serrated, broadly linear leaves that are 100–200 mm (3.9–7.9 in) long and 5–14 mm (0.20–0.55 in) wide on a thin petiole 20–60 mm (0.79–2.36 in) long, with between ten and twenty-five triangular teeth on each side. The flowers are borne on a head containing about sixty flowers with broadly linear to egg-shaped, dark reddish brown involucral bracts 40–50 mm (1.6–2.0 in) long at the base of the head. The flowers are yellow with a perianth 38–41 mm (1.5–1.6 in) long and a pistil 44–46 mm (1.7–1.8 in) long. Flowering occurs from September to October and the fruit is a glabrous, elliptical to egg-shaped follicle about 15 mm (0.59 in) long. [2] [3] [4]
This banksia was first formally described in 1996 by Alex George in the journal Nuytsia and given the name Dryandra corvijuga from specimens collected in 1986 near Ravensthorpe. [2] [5] In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia corvijuga. [6] [7] The specific epithet (corvijuga) is derived from Latin words meaning "a crow or raven" and "paired or yoked together", referring to the Ravensthorpe Range. [2]
Banksia corvijuga grows in dense shrubland in the Ravensthorpe Range. [2] [4]
This banksia is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife [4] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [8]
