Description:  "Shrub 1-5 m high, cultivated and occasionally naturalized near sea level; stems hollow; petiole 2.5-15 cm long; leaf blades ovate to lanceolate, 10-25 cm long, truncate to shallowly cordate at base, long-acuminate; sepals suborbicular, 5-6 mm long; corolla 5-9 cm long, finely tomentose without, rich pink, deeper pink to purple at base, the limb spreading to 11 cm in diameter; filaments unequal, dilated and pilose at base; fruit ovoid to subglobose, 1.5-2 cm long, the seeds covered with long, woolly, brown trichomes." (Smith, 1991)  "Immediately recognizable from other morning glories by its shrubby, not vine-like, habit" (Stone, 1970; pp. 491-492).

Habitat/ecology:  In Fiji, "cultivated and occasionally naturalized near sea level" (Smith, 1991; pp. 63-64). In New Caledonia, "largement répandu et très commun dans les jardins bien que d'introduction récente. Fructifie peu ou pas malgré la floraison belle, abondante et presque continue" (MacKee, 1994; p. 41). "Parfois cultivée comme plante ornementale. Plante grimpant le plus souvent sur les arbustes, en lisière de forêt humide, dans les formations de l'arrière-plage et se répandant dans les anciennes cultures" (Heine, 1984; pp. 65-66).
