Acacia mutabilis Maslin subsp. mutabilis




Occurs from Kondinin–Borden area E to Cape Arid Natl Park (E of Esperance), south-west W.A.


Shrub 0.3–1.2 m high. Stipules rarely persistent, c. 1 mm long. Phyllodes linear to linear-oblanceolate, obovate-oblanceolate or narrowly oblong-elliptic, usually straight to shallowly incurved, (1–) 1.5–5 (–5.5) cm long, (2–) 3–5 (–7) mm wide, l:w = (3-) 5–14; gland 5–15 mm above pulvinus. Peduncles 5–10 (–15) mm long.


Grows in sand, sandy clay, clay, loam and sandy loam, in heath, open shrub or tree mallee and as understorey in open eucalypt woodland, often at the periphery or near salt lakes or marshes, mostly in flatlands.


W.A.: near Kau Rock, T.E.H.Aplin 4072 (CANB, PERTH); 8 km S of Lake King towards Ravensthorpe, B.R.Maslin 3437 (MEL, PERTH); 12.8 km SW of Borden, K.R.Newbey 1441 (PERTH); Gnowangerup, at golf course, J.W.Wrigley WA/68 4827 (PERTH).


Phyllodes very variable in shape and size: shallowly recurved phyllodes occur near Truslove (c. 60 km due N of Esperance) and specimens with unusually short phyllodes occur E of Ravensthorpe and in the Mt Madden–Lake King area (N of Ravensthorpe). Specimens with shallowly incurved phyllodes differ from subsp. incurva in having longer peduncles and/or the gland farther removed from the pulvinus.
