Acacia nanopravissima Molyneux & Forrester

Common Name

Little Kooka Wattle




Known only from type locality, Splitters Ck, S of Wulgulmerang in East Gippsland, Vic. Currently known by a single small population on the Wombargo Ra. in the upper catchment of Little R., a tributary of the Snowy R. The population comprises small fragmented stands in close proximity extending across a slope overlooking and S of Splitters Ck, a tributary of Little R.; an isolated stand of five plants occurs just E of the Splitters Ck subpopulation.


Erect shrub 0.4–0.6 (–1) m high, readily suckering. Branchlets glabrous. Phyllodes crowded, markedly inequilateral, generally obdeltate with adaxial margin conspicuously rounded and its proximal edge ±parallel to branchlet, 3–8 mm long, 4–8 mm wide, mucronulate, grey-green, glabrous; imperfectly 2-nerved, lateral nerves not anastomosing; gland prominent, (1.6–) 2.3–3.7 (–4.5) mm above pulvinus, similar in form to A. kettlewelliae. Inflorescences (6–) 8–10-headed racemes; raceme axes (0.5–) 1.2–2.7 (–6) cm long (exceeding the phyllodes); peduncles 2–4 mm long, glabrous; heads globular, 3–4 mm diam. (dry), 7–9-flowered, golden. Flowers 5-merous; sepals united. Pods and seeds not seen.


Flowers late Aug.–early Oct.


Grows in dry open forest on high rocky ground in shallow soils derived from sediments.


Vic.: Wulgulmerang, Little R., 15 Jan. 1971, A.C.Beauglehole s.n. (MEL 563409); Splitters Ck, Wulgulmerang, 11 Jan. 1949, N.A.Wakefield s.n. (MEL 544638); Splitters Ck crossing, Limestone Ck Rd, 22 Sep. 1990, W.M.Molyneux & S.G.Forrester s.n. (MEL 1587015).


A slow growing dwarf species that spreads by suckering; plants do not seem to set fruit. It was treated as a dwarf variant of A. pravissima by B.R.Maslin in Fl. Australia 11A: 331 (2001). Acacia infecunda and A. tabula occur in the same area and were treated as dwarf variants of A. boormanii and A. buxifolia subsp. buxifolia in Fl. Australia 11A: 334 & 341 (2001) respectively.

Most closely related to A. pravissima which differs in its taller stature, generally larger phyllodes and larger heads, see W.M.Molyneux & S.G. Forrester (Muelleria 26(1): 54, Table 1 (2008), Table 1) for a detailed comparison of these two species. According to W.M.Molyneux & S.G. Forrester (Muelleria 26(1): 56 (2008) the nearest stands of A. pravissima to those of A. nanopravissima are on the upper Gibbo R., some 90 km to the NW.
