Acacia torticarpa is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area in western Australia.
Description
The shrub has branchlets are hairy and marked with parallel grooves and have persistent stipules that have a length of 3 to 4 mm (0.12 to 0.16 in). Like most species of Acacia it has phyllodes rather than true leaves. The hairy and leathery evergreen phyllodes are patent to inclined and have a narrowly linear to oblanceolate-linear shape and are usually incurved with a length of 3.5 to 5.5 cm (1.4 to 2.2 in) and a width of 2 to 3.5 mm (0.079 to 0.138 in) and have six distant and raised nerves.[1] It is thought to bloom in July[2] when it produces simple inflorescences that occur in pairs in the axils with spherical flower-heads that have a 5 mm (0.20 in) diameter and containing 17 to 18 yellow flowers. Following flowering hairy and leathery seed pods form that have a flexuose-linearshape with a length of up to 20 m (66 ft) and a width of 2 mm (0.079 in). The glossy tan coloured seeds inside have an oval to elliptic shape with a length of 1.5 to 2 mm (0.059 to 0.079 in).[1]
Taxonomy
It was first formally described by the botanists Richard Sumner Cowan and Bruce Maslin in 1990 as a part of the work Acacia Miscellany. Some new microneurous taxa of Western Australia related to A. multineata (Leguminosae: Mimosoideae: Section Plurinerves) from Western Australia as published in the journal Nuytsia. It was reclassified as Racosperma torticarpum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006.[3] It is similar in appearance to Acacia caesariata.[1]
Distribution
It is native to an area in the Wheatbelt region of Western Australia.[2] It has a limited and disjunct distribution nd is only known from two populations near Yorkrakine and about 120 km (75 mi) further south around South Kumminin.[1]
