Acacia ptychophylla is a shrub belonging to the genus Acacia and the subgenus Juliflorae the is endemic to arid areas of north western Australia.
The bushy shrub typically grows to a height of 0.6 to 2.5 metres (2 to 8 ft)[1] with a dense, spreading, multistemmed, flat-topped or rounded habit. It has glabrous and resin ribbed branchlets that are reddish brown in colour but yellow-green at the extremities. Like most species of Acacia it has phyllodes rather than true leaves. The glabrous, coriaceous and evergreen phyllodes have an oblong to narrowly oblong-elliptic shape and are straight or occasionally shallowly incurved. The phyllodes have a length of 2 to 5.5 cm (0.79 to 2.17 in) and a width of 3 to 10 mm (0.12 to 0.39 in) and often have a small callose tip at the apex, they usually have five to eight prominent and raised longitudinal nerves.[2] It blooms from April to August and produces yellow flowers.[1] The simple inflorescences are in the form of erect cylindrical flower-spikes with a length of 2 to 4.5 cm (0.79 to 1.77 in) packed with golden coloured flowers. Following flowering flat woody seed pods that are encrusted with resin form. The pods have a narrowly oblong to oblong-elliptic shape and are narrower at the base. The light brown, straight or shallowly curved pods are 5 to 7 cm (2.0 to 2.8 in) in length and have obliquely longitudinal nerves. The broen seeds inside the pods have an oblong-elliptic shape and are 4 to 5 mm (0.16 to 0.20 in) in length with a dark pleurogram.[2]
