Acacia clunies-rossiae Maiden, J. & Proc. Roy. Soc. New South Wales 49: 486 (1916)

Kowmung Wattle

Bushy shrub or tree 2–6 (- 10) m high. Branchlets often pruinose, with indumentum of sparse to moderate, minute, appressed, straight hairs. Phyllodes narrowly oblong-elliptic to oblanceolate, 3.5–6.5 cm long, 4–10 mm wide, mucronulate, thin, glaucous, with indumentum as on branchlets (young tips greyish white due to denser indumentum), 1-nerved; lateral nerves obscure; gland 2–7 mm above pulvinus, submerged and swollen within the lamina in a pouch fashion like in A. kettlewelliae . Inflorescences racemose; raceme axes 1.5–4 cm long, with indumentum as on branchlets; peduncles 2–4 mm long; heads globular, small, 7–9-flowered, bright light golden. Flowers 5-merous; sepals free; ovary glabrous. Pods raised over seeds along midline, to 6 cm long, 7–10 mm wide, firmly chartaceous, pruinose, glabrous. Seeds longitudinal, oblong-elliptic to slightly ovate, 5.5–6 mm long, shiny, black; aril clavate.

Restricted to the valleys of the Kowmung and adjacent Cox’s R. in the Blue Mtns, N.S.W. Grows in skeletal soil on rocky slopes of commonly slate or shale, or in gravel and alluvium along creeks, in dry sclerophyll Eucalyptus forest.

Most closely related to A. caesiella and A. barringtonensis but distinguished especially by its glabrous ovary, generally fewer-flowered heads and submerged, swollen, pouch-like gland (somewhat similar to those of A. kettlewelliae ).
