Acacia ancistrophylla var. lissophylla (J.M.Black) R.S.Cowan & Maslin

Common Name

Dwarf Myall




Discontinuous in southern W.A. from near Balladonia, Kalannie and from between Lake Grace and Newdegate, in S.A. from Ceduna on the Eyre Peninsula to Pine Point on the Yorke Peninsula and also near Sutherlands in the Murray region, and in north-western Vic. in the Rosebery–Swan Hill area.


Phyllodes patent to erect, linear or linear-oblanceolate, straight to slightly curved, mostly 1.5–4.8 cm long and 1–3.5 (–4) mm wide, l:w = 7–20, with an acute, curved tip; nerves and stomata ±distinct. Peduncles 2–5.5 mm long; heads 11–18-flowered; sepals free or rarely united basally. Pods raised over and slightly constricted between seeds, straight to shallowly curved, to 3 mm wide, glabrous. Seeds broadly elliptic, 3 mm long, dark brown; aril subapical, thin, closely appressed to seed, cream-coloured.


Grows mostly on flats in sandy loam and loam over limestone, usually in mallee communities.


W.A.: 28 km SW of Balladonia Motel, K.Newbey 11745 (PERTH). S.A.: 24 km due E of Kadina, B.R.Maslin 4525 (CANB, MEL, NSW, PERTH); c. 10 km NE of Port Neill on Lincoln Hwy, D.J.E.Whibley 1977 (K, PERTH). Vic.: Goschen area, 14 Sept. 1989, T.Langdon (MEL).


Variety lissophylla is most common on the Eyre Peninsula, S.A., but more scattered elsewhere in that state, and rare in W.A. and Vic. This variety differs from the other varieties comprising the species by its phyllode proportions and by seed morphology. None of the W.A. collections are fruiting and only very few of those from S.A.; additional fruiting material would be valuable. Acacia ancistrophylla var. lissophylla is at least superficially similar to A. lineolata subsp. lineolata.
