Description.

Perennial herb with twining or (occasionally) trailing stems to at least 50 cm, plant adpressed pubescent to more or less strigose. Leaves petiolate, not strongly dimorphic, 2.1-7.5 × 1-1.5 cm, narrowly deltoid, basally truncate and shortly cuneate onto the petiole, the central lobe linear, oblong, lanceolate or oblanceolate, acute, entire, 2-6 mm wide, basal auricles always present, 2-10 mm long, usually simple, occasionally bifurcate or toothed; petioles 6-10 (-20) mm. Flowers solitary or paired (rarely 3), pedunculate, axillary; peduncles mostly 1-3.5 cm long, not recurved in fruit; bracteoles 1.5-2.5 mm long, filiform; pedicels 4-10 mm; sepals 4.5-6 × 3-4.5 mm, broadly elliptic to obovate, rounded and mucronate at apex, margin somewhat scarious, dorsal surface pubescent; corolla 1-1.8 cm long, pink, lobed with broadly triangular lobes, midpetaline bands pilose towards apex; ovary glabrous; style glabrous, divided 4-6 mm above base, stigmas c. 2 mm. Capsule glabrous; seeds nearly smooth with obscure tubercles. [ Johnson 2001: 14-15, f. 3-4, map 3]

Distribution.

Widespread in Australia, except the east coast, but most abundant in South Australia and Western Australia (Chorney 991, Symon 3578, Aplin 1792; Lazarides & Palmer 005; Elkins & Sweedman 20050042, Rechinger 58286).

Notes.

The usually very obviously twining stems with adpressed indumentum and narrowly deltoid auriculate leaves and straight peduncles serve to distinguish this species. The seeds are only obscurely tuberculate unlike those of Convolvulus graminetinus .

Robert Brown did not cite either a precise location or specimen in the protologue so Johnson was wrong to cite the Port Lincoln collection as holotype as there is another syntype mounted on the same sheet from a different location. In order to avoid future uncertainty we are formally designating the Port Lincoln collection at BM as lectotype. There is an isolectotype at Kew.
