Type.

Plate in Bot. Mag. t.1007 (1807), lectotype, designated here; AUSTRALIA, plant from Hawkesbury River, New South Wales, collected by R. Brown on left side of sheet Brown s.n. [Bennett 2767] (epitype BM!, designated here).

Description.

Perennial herb with trailing or twining stems reaching at least 50 cm, stems crisped-pubescent, stouter than in other Australian species, commonly exceeding 2 mm in width. Leaves petiolate, variable in size but not markedly dimorphic, 2.5-8 × 1-3.5 cm, deltoid, apex obtuse and mucronate, margin crenate or repand, base broadly cordate and cuneate onto the petiole with prominent auricles, these variable, simple, toothed or laciniately lobed; petioles 1.2-2.5 cm, diminishing in size upwards. Flowers 1-4, usually clearly cymosely arranged, axillary, pedunculate, not recurved in fruit; peduncles 1-2 per axil, 2-6 cm, usually straight; bracteoles 1-3 mm long, filiform; pedicels 8-25 mm, very variable in length and strikingly unequal in individual inflorescences, often sinuate; sepals 5.5-7 × 3.5-5 cm. narrowly elliptic, terminating in a recurved mucro; corolla 1.2-1.5 cm, pinkish, lobed with triangular lobes, midpetaline bans pubescent near apex; ovary glabrous; style glabrous, divided 3-7 mm above the base, stigma 2 mm. Capsule glabrous, seeds tuberculate, unwinged. [ Johnson 2001: 20-22, f. 5-6, map 2]

Distribution.

Australia: eastern coast of New South Wales and Queensland (Beckler s.n., McBarron 4110, Coveny 11781, Mossman 1854), apparently rather rare.

Notes.

The most robust Australian species, the peduncles usually bearing several flowers and unusually sometimes with two peduncles per leaf axil. Most similar to Convolvulus clementii but leaves more obviously deltoid in form, the corolla larger and the seeds unwinged. Johnson 3364 (P) from Northern Territory will key out here (unwinged fruit, paired 2-flowered cymes) but flowers and location fit Convolvulus clementii .

All Australian and New Zealand native species were once treated under this name following Bentham (1869).
