Acacia infecunda Molyneux (ms)

Shrub 0.3–0.5 (–1.2) m high. Branchlets not pruinose. Phyllodes linear, 12–25 mm long; 1–1.5 mm wide, straight, obliquely and excentrically mucronate, thin, grey-green to sub-glaucous, glabrous, midrib not prominent, anastomoses absent; gland not prominent, 4–10 mm above pulvinus. Inflorescences racemose; 1 per axil. Inflorescences 8–10-headed racemes; raceme axes (3–) 10–20 (–30) mm long; peduncles 1.5–3 mm long; glabrous; heads globular; (5–) 7 (–9)-flowered, golden. Flowers 5-merous; sepals united. Pods and seeds not seen.

Occurs at Splitters Ck, S of Wulgulmerang, north-eastern Vic. Grows in dry open forest on high rocky ground in shallow soils derived from sediments. Acacia tabula and A. nanopravissima occur in this same area (in Fl. Austral . these species were treated as dwarf variants of A. boormanii and A. pravissima respectively).

Plants of A. infecunda are slow growing, dwarf shrubs (usually not exceeding c. 0.5 m high); they spread by suckering and do not seem to set fruit. In Fl. Australia this species was treated as a dwarf variant of A. boormanii which, apart from its taller stature, differs most obviously from A. infecunda , in having longer phyllodes (mostly 3–6 cm).
