Acacia anastema
Acacia anastema, commonly known as sandridge gidgee[2] or sandplain gidgee,[3] is a species of flowering plant in the family Fabaceae and is endemic to a fairly small area of semi-arid land east of Carnarvon. It is a tree with linear phyllodes, spikes of golden yellow flowers, and pods up to 140 mm (5.5 in) long. DescriptionAcacia anastema is a tree that typically grows to a height of up to 6 m (20 ft) with more or less sticky branches and up to 3 trunks. Its phyllodes are linear, flat and curved, 110–320 mm (4.3–12.6 in) long, 2–6 mm (0.079–0.236 in) wide and leathery. The flowers are borne in a spike 20–40 mm (0.79–1.57 in) long and 6–8 mm (0.24–0.31 in) wide, in the axils on a peduncle 10–20 mm (0.39–0.79 in) long, each spike with densely crowded golden yellow flowers. Flowering occurs from July to September and the fruit is a linear-cylindrical pod up to 140 mm (5.5 in) long and 2–3 mm (0.079–0.118 in) wide containing seeds 5.0–5.5 mm (0.20–0.22 in) long.[2][4][5] TaxonomyAcacia anastema was first formally described in 1983 by Bruce Maslin in the journal Nuytsia from specimens he collected on the road to Towrana station in 1981.[5][6] The specific epithet (anastema) means 'upwards thread',[7] and refers to the tall growth habit of the species.[5] Distribution and habitatThis species of Acacia grows on sand dunes and sand ridges between Woodleigh station and Ellavalla Station in the Carnarvon bioregion in Northern Western Australia.[2][3][4] See alsoReferences
