A liana endemic to Northern Australia, recorded in Queensland, Northern Territory and Western Australia states. According to Austin (1993), it occurs in Eucalyptus woodlands and open forests on sandy and skeletal soils, although Johnson (2012) noted this species is morphologically very variable and may contain several taxa. This species is part of a group of Australian endemic species nested in Ipomoea Clade A1, likely the result of long distance dispersal from the American continent followed by species diversification in Australia.

DESCRIPTION (from: Austin et al., 1993): Perennial vines; stems twining, woody, glabrous. Leaf blades broadly ovate, 7.5-12 cm long, 6-9 cm broad, basally cordate, the margins entire, apically acute to narrowly obtuse, emarginate, glabrous or with occasional trichomes on the midrib, the petiole 2-7 cm long. Inflorescence axillary, cymose, 1-5 flowered, often compound; peduncles 8-30 mm long. Flowers on pedicels 1.5-3 cm long, glabrous; sepals subequal, the outer two broadly ovate to orbicular, coriaceous, 8-15 cm long and broad, apex rounded, glabrous, very wrinkled at maturity, the inner broadly oblong of similar length but narrower; corolla funnelform, 6-10 cm long, pink with a darker throat, mid-petaline bands glabrous; stamens unequal, inserted 1.5-2 cm above the corolla base, the filaments 2.5-3.5 cm long, pubescent in the lower half, anthers oblong, 7-8 mm long; ovary 2-locular, ovoid, glabrous, the style 4-5 cm long, the stigma biglobose. Fruits capsular, globose to globose-ovoid, with a persistent style base, 1.2-1.5 cm long, brown; seeds 4 or fewer, 5-6 mm long, dark olive brown, loosely pubescent with longer trichomes on the margins.
