Acacia lirellata Maslin & A.R.Chapm. subsp. lirellata




Discontinuous in the wheatbelt from the Coorow–Watheroo area, and c. 180 km SE to the Northam–Quairading area, W.A.


Phyllodes sessile, decurrent, terete to quadrangular in section, occasionally subflat, strongly curved to circinnate or serpentinous, 5–13 cm long, 0.8–1.5 mm wide, 8-nerved. Bracteoles obtuse. Pods submoniliform.


Grows in red sandy loam, loam, sand, clayey sand and gravel, in heath and remnant roadside vegetation.


W.A.: c. 19 km S of Coorow on Midlands Rd, C.Chapman 3 (BRI, CANB, MEL, NSW, PERTH); 17.7 km N of Watheroo, R.T.Lange 2 (PERTH); 3.2 km W of Quairading on the road to York, B.R.Maslin 489 (CANB, K, MEL, PERTH).


Terete phyllode forms of A. tetraneura could be confused with subsp. lirellata. Acacia tetraneura is most readily distinguished by its 4-nerved, non-decurrent phyllodes and conspicuous bracteoles. Also related to A. aprica and A. arcuatilis but distinguished from both by its decurrent, deeply furrowed phyllodes.
