Acacia luteola Maslin, Nuytsia 1: 453; 455, fig. 23 & 489, map 8 (1975)
Shrub normally 0.2– 0.7 m high. Branchlets usually antrorsely puberulous and short-pilose admixed. Pinnae normally 2 or 3 pairs, 2– 5 mm long (proximal pinnae), 3– 12 mm long (distal pinnae), the apices flat, elliptic and often recurved; petiole 1– 2 mm long; rachis 1.5– 4 (– 10) mm long; pinnules 2– 3 pairs (proximal pinnae), 2– 5 pairs (distal pinnae), normally narrowly oblong, 2– 6 mm long, 0.5– 1 mm wide, recurved to revolute, obliquely narrowed at apex, green, glabrous to hirsutellous; gland on rachis at base of pinnae, occasionally also on petiole, sessile, not prominent. Inflorescences simple, normally 1 per axil; peduncles 10– 20 mm long, usually hirsutellous to short-pilose; heads globular to cylindrical, 16– 30-flowered, cream to pale yellow. Flowers 5-merous; sepals 1/2- 3/4-united, 1-nerved; petals sparsely hirsutelllous, 1-nerved. Pods 2– 5 cm long, 4– 6 mm wide, puberulous-hirsutellous to short-villous. Seeds oblique, elliptic, 3 mm long.
Occurs from the Mount Barker– Stirling Ra. area SE to Albany and Beaufort Inlet, south-western W.A. Grows in sand, sandy clay and loam in low lying (seasonal) swamps in woodland and mallee communities.
A member of the ‘ A. drummondii group’ similar to A. varia var. varia , especially in floral morphology. A variant with glabrous, prominently ribbed branchlets and glabrous peduncles and petals occurs at Albany and Stirling Ra. (e.g. E.Pritzel 349 , AD, B, E, G-DC, K, L, LY, M, MO, NSW, P, PR, US, Z). This variant is sometimes sympatric with the typical variant.
