Persoonia hakeiformis

Persoonia hakeiformis is an erect or spreading to low-lying shrub that typically grows to a height of 0.3–1.8 m (1 ft 0 in – 5 ft 11 in) with smooth, mottled grey bark, flaky near the base, and branchlets that are hairy when young. The leaves are arranged alternately along the stems, linear, 15–50 mm (0.59–1.97 in) long and 0.8–1.4 mm (0.031–0.055 in) wide and grooved on the lower surface. The flowers are arranged singly or in groups of up to sixty along a rachis up to 100 mm (3.9 in) long, each flower on a pedicel 3–7 mm (0.12–0.28 in) long. The tepals are bright yellow, 8–12 mm (0.31–0.47 in) long, the lowest tepal deeply sac-like with its anther fused to it. Flowering occurs from November to January and the fruit is a smooth drupe 8–13 mm (0.31–0.51 in) long and 5–6 mm (0.20–0.24 in) wide.[2][3][4][5]

Persoonia hakeiformis was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis.[6][7]

This geebung has been collected at the Boyagin Nature Reserve, Tarin Rock and Newdegate in the south-west of Western Australia, where it grows in heath and woodland.[3]

Persoonia hakeiformis is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[2] meaning that it is poorly known and from only one or a few locations.[8]
