Persoonia rudis is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub with hairy young branchlets, linear leaves, and yellow flowers borne in groups of five to thirty on a rachis 3–100 mm (0.12–3.94 in) that continues to grow after flowering.
Description
Persoonia rudis is an erect shrub that typically grows to a height of 0.2–1 m (7.9 in–3 ft 3.4 in) with young branchlets that are covered with pale brown or greyish hair. The leaves are linear, 15–45 mm (0.59–1.77 in) long and 0.7–1.4 mm (0.028–0.055 in) wide with a pointed but not sharp tip. The flowers are arranged in groups of five to thirty along a rachis 3–100 mm (0.12–3.94 in) long that continues to grow after flowering, each flower on a pedicel 2–10 mm (0.079–0.394 in) long with a leaf or a scale leaf at the base. The tepals are yellow, 8–14 mm (0.31–0.55 in) long and the anthers are yellow. Flowering occurs from October to January and the fruit is a smooth, moderately hairy drupe 8.5–9 mm (0.33–0.35 in) long and 5.5–6 mm (0.22–0.24 in) wide.[2][3][4][5]
Taxonomy
Persoonia rudis was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected in the Swan River Colony by James Drummond.[6][7]
Distribution and habitat
This geebung grows in low heath and forest between Three Springs and Mogumber in the Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain biogeographic regions in the south-west of Western Australia.[3][5]
Conservation status
Persoonia rudis is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[5] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[8]
