Acacia cupularis Domin, Vestn. Krl. Ceskf Spolecn. Nauk, Tr. Mat.-Prr . 2: 45 (1923)
Coastal Umbrella Bush
Glabrous, open to subdense shrub usually 1–2.5 m high, to 2.5 m wide. Branchlets commonly dark red-brown, often lightly pruinose. Phyllodes subdistant, ascending to erect, narrowly linear, straight, 3–8 cm long, 1–4 (–5) mm wide, rounded-obtuse, with minute and central mucro, ᮱thick, finely wrinkled when dry, subglaucous to dark green; midrib not prominent; glands 2 or 3, lowermost 3–14 mm above pulvinus, distal glands smaller with one at base of mucro. Inflorescences 2 or 3-headed racemes; raceme axes 1–7 mm long; basal bracts caducous but bract scars persistent; peduncles 2–6 mm long; heads globular, subdense, 16–22-flowered, golden. Flowers 5-merous; sepals united into a truncate calyx. Pods erect, submoniliform, to 7 cm long, 4–5 mm wide, crustaceous, breaking readily at constrictions, commonly dark brown. Seeds longitudinal, oblong, 3–5 mm long, dull, light brown; aril orange to scarlet.
Widespread in coastal and near coastal areas of southern Australia from Albany, W.A., through S.A. to the Vic. border, extending inland to Dimboola, western Vic. and Three Springs, W.A. Grows in sand, sometimes on dunes, or in loam or sandy clay in ‘Mallee’ communities.
Acacia cupularis is a member of the ‘ A. bivenosa group’ and until recently was considered conspecific with A. ligulata , fide A.R.Chapman & B.R.Maslin, Nuytsia 8: 260 (1992). Narrow phyllode forms of A. ligulata are most reliably distinguished from A. cupularis by wider, woody pods which don’t break readily at constrictions between the seeds and phyllodes which are thicker (therefore coarsely wrinkled when dry) and uncinate with a recurved to straight mucro. Phyllodes may resemble those of A. maxwellii which differs in having pubescent branchlets and longer peduncles; also, A. maxwellii is prostrate shrub while A. cupularis is normally erect, however, a prostrate form is know from coastal cliffs in S.A. Superficially similar to A. crassiuscula (W.A.) and A. anceps x nematophylla (S.A.) .
