Description
editPersoonia graminea is an erect to weak, low-lying shrub that typically grows to a height of 20–60 cm (7.9–23.6 in), with its young branchlets covered with greyish hairs. The leaves are linear, 100–350 mm (3.9–13.8 in) long and 2–8 mm (0.079–0.315 in) wide, usually in small groups at the end of each year's growth. The flowers are arranged in groups of ten to twenty-five along a rachis up to 220 mm (8.7 in) long, each flower on a pedicel 2–6 mm (0.079–0.236 in) long. The tepals are egg-shaped to lance-shaped, bright yellow to green, 4.2–4.5 mm (0.17–0.18 in) long with bright yellow to green anthers. Flowering occurs from November to January and the fruit is a drupe 4.5–6 mm (0.18–0.24 in) long and 2–3 mm (0.079–0.118 in) wide containing a single seed.[2][3][4][5]
Taxonomy
editPersoonia graminea was first formally described in 1810 by Robert Brown in Transactions of the Linnean Society of London from specimens he collected at King George Sound in December 1801.[6][7]
Distribution and habitat
editThis geebung is found on poorly-drained or loamy soils in swamps, heath, woodland and forest within 40 km (25 mi) of the coast between Margaret River and Albany.[3][4]
Conservation status
editPersoonia graminea is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[5]
