Acacia manipularis R.S.Cowan & Maslin, Nuytsia 10: 72 (1995)
Spreading, viscid shrub 0.75–1 m tall. Branchlets terete, obscurely ribbed, verruculose, glabrous, resinous. Phyllodes fasciculate, 2–6 per node, patent to inclined, filiform, straight to very slightly curved, terete, 2–3 cm long, 0.5 mm diam., mucronulate, flexible, glabrous, very finely longitudinally wrinkled when dry, superficially nerveless. Inflorescences simple, 1 per axil; peduncles 20–25 mm long, glabrous, resinous; heads globular, 6 mm diam., 38-flowered, golden; bracteoles peltate, with ovate, acute laminae. Flowers 5-merous; sepals 1/3–1/2-united; petals 1-nerved. Pods narrowly oblanceolate, flat, straight, to 5.5 cm long, 5–6 mm wide, woody, longitudinally obliquely nerved, glabrous, resinous-viscid, dehiscing elastically from apex; margins thickened. Seeds oblique, broadly oblong-elliptic, 4–5 mm long, glossy, brown; aril apical, conical.
Known only from Mount House and Tableland Stns, Kimberley, W.A. Co-dominant with Melaleuca sp. and Eucalyptus brevifolia in tall shrubland, also recorded from a shale plateau.
Acacia manipularis differs from its most closely related members of the ' A. stigmatophylla group', A. subternata and A. delicatula , by its obscurely ribbed branchlets and longer phyllodes. It is further distinguished from A. delicatula by its acute (not acuminate) bracteoles and from A. subternata by its 1-nerved (not striate) petals. See R.S.Cowan & B.R.Maslin, Nuytsia 10: 72–74 (1995) for discussion.
