Pods ±terete, to 5 cm long, 2.5–3.5 mm wide, acuminate, thinly crustaceous-coriaceous, curved (especially upon dehiscence), red-brown, coarsely striate, minutely appressed-puberulous to ±glabrous.

W.A.: West Mt Barren, R.Coveny 3312 et al. (NSW, PERTH); top of East Mt Barren, R.J.Cumming 1062 (PERTH); W side of Mt Maxwell, B.R.Maslin 3476 (PERTH).


Included by L.Pedley, Contr. Queensland Herb. 11: 11 (1972), as an atypical member of the ‘A. lycopodiifolia group’; but its closest affinities are with A. laricina (fide B.R.Maslin, Nuytsia 2: 101 (1976)). Sometimes confused with A. simulans.
