Spyridium spadiceum is a species of flowering plant in the family Rhamnaceae and is endemic to the south of Western Australia. It is an erect or semi-prostrate shrub with narrowly oblong to oval leaves and heads of hairy flowers with brown bracts at the base.
Description
Spyridium spadiceum is an erect slender, or weak semi-prostrate shrub that typically grows to a height of 0.15–3 m (5.9 in–9 ft 10.1 in), its branches covered with soft, sometimes rust-coloured hairs. The leaves are narrowly oblong to oval, 1–3 mm (0.039–0.118 in) long, softly-hairy on the upper surface and white on the lower side, the veins sometimes covered with rust-coloured hairs. The flowers heads are arranged in cymes with many broad, brown bracts at the base. The sepal tube is about 2 mm (0.079 in) long and densely hairy.[2][3]
Taxonomy
This species was first formally described in 1837 by Eduard Fenzl who gave it the name Trymalium spadiceum in Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel.[4][5] In 1863, George Bentham changed the name to Spyridium spadiceum in Flora Australiensis.[6] The specific epithet (spadiceum) means "brown" or "date-coloured", referring to the floral bracts.[7]
Distribution and habitat
Spyridium spadiceum grows on granitic hills in the Porongurup Range and at Albany in the Jarrah Forest bioregion in the south of Western Australia.[3][8]
Conservation status
Spyridium spadiceum is listed as "Priority Four" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is rare or near threatened.[9]
