Acacia filamentosa is a shrub belonging to the genus Acacia and the subgenus Juliflorae that is endemic to north western Australia.
Description
[edit]The shrub is typically grows to a height of 0.9 to 2 metres (3 to 7 ft).[1] It has glabrous and resinous branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen and ascending phyllodes have a coarsely filiform shape are curved to shallowly sinuous with a length of 15 to 25 cm (5.9 to 9.8 in) and a diameter of around 1 mm (0.039 in) with eight distant, obscure and resinous veins.[2] It blooms from June to September producing yellow flowers.[1] It has simple inflorescences that occur in pairs in the axils, the cylindrical flower-spikes have a length of 20 to 25 mm (0.79 to 0.98 in) and a diameter of around 6 mm (0.24 in) and are densely flowered. The crustaceous to thin-coriaceous seed pods that form after flowering have a linear shape and are slightly raised over and constricted between the seeds. The pods have a length of up to around 11 cm (4.3 in) and a width of around 3 mm (0.12 in) and are longitudinally striated and glabrous. The brown seeds have a yellow coloured peripheral band and are arranged longitudinally within the pods. The seeds have a narrowly oblong shape with a length of 6 to 7 mm (0.24 to 0.28 in) and a pale yellowish aril.[2]
Distribution
[edit]It is native to an area in the Kimberley region of Western Australia[1] around 150 to 300 km (93 to 186 mi) south west of Wyndham where it has a scattered distribution across a few areas including Adcock Gorge between Pentecost Downs Station and Kalumburu and is commonly situated on sandstone hills.[2]
