Acacia verricula R.S.Cowan & Maslin, Nuytsia 7: 197; 193, fig. 2J–L (1990)
Spreading shrub 0.5–3 m high, rarely 2 m high tree. Branchlets resinous, sparingly puberulous. Phyllodes narrowly- or linear-elliptic to oblanceolate, inequilateral, obtuse to acute, 1.5–3 cm long, 3–6 mm wide, thin-coriaceous, straight to slightly curved, glabrous or sparsely appressed-hairy on margins, resinous, with 2 or 3 distant main nerves sometimes evident, the secondary nerves mostly impressed and anastomosing in a regular reticulum; gland mostly 2–6 mm above pulvinus. Inflorescences 1- or 2-headed racemes; raceme axes 1–6 mm long, often resinous; peduncles mostly 3–6 mm long, puberulous, the hairs often golden; heads globular, 4–5 mm diam., 25–35-flowered, golden. Flowers 5-merous; sepals free. Pods linear, mostly undulate, arcuate, to 5 cm long, 2–4 mm wide, glabrous or few antrorsely curved micro-hairs, markedly nitid-resinous. Seeds longitudinal, elliptic, 3–3.5 mm long, glossy, brown; aril apical to subapical.
Occurs sporadically from Chiddarcooping Hill and Trayning S to the Fitzgerald R. and E to near Sparkle Hill and Buningonia Spring in south-western W.A. One outlier was collected at Madura, c. 320 km ESE of Buningonia Spring. Grows in clay soil, loam, and sandy or gravelly loam to brown, red or white sand.
A member of the ‘ A. flavipila group’ most nearly related to A. ixiophylla and A. vittata ; A. lobulata is also related but more distantly. Can be confused with A. consobrina which is most readily distinguished by its phyllodes having a normally denser indumentum with the hairs on the surface of the lamina and the reticulum normally less well developed and with clearly elongated nerve-islands.
The A. ixiophylla referred to by B.R.Maslin, Nuytsia 1: 329 (1974), in the protologue of A. redolens , was subsequently described as A. verricula .
