Sprawling or upright perennial (can die back severely in dry times) shrub to 70 cm tall; branchlets velvety, with glandular and stellate hairs below longer simple hairs. Leaves ovate, to 8 cm long and 6 cm wide, slightly discolorous; apex shortly acuminate to acute. Flowers solitary in upper axils; calyx 5-angled and ribbed, ± urceolate, 10–18 mm long; lobes ovate, clearly keeled basally, long-acute at apex; corolla just exceeding calyx; lobes 4–9.5 mm long, rounded apically; staminal column 1–2 mm long, glabrous; styles 10–17. Fruit very broadly ovoid, brownish, c. 10 mm high, stellate-pubescent with longer hairs along sutures, adjacent mericarps adhering for less than a quarter of their surface, eventually dissociating; mericarps 3-seeded, 6.5–7 mm high, 3–3.5 mm wide, notched at base; apically rounded, acuminate or with an erect awn to 0.5 mm long.
MuM, MSB, RobP. All mainland states. Rare, confined to red loam ridges and dunes near the floodplain of the Murray River in the far north-west (e.g. Hattah, Mildura and Robinvale areas). Flowering after summer rains.
Abutilon otocarpum is a very variable species, usually most easily recognised by the distinctly 5-keeled calyx. The fruit is enclosed by the expanded lower half of the calyx when young and often has the spent corolla still attached at its apex.
