A species scattered in seasonally dry tropical forests below 1000 m in South America, most common in the Chiquitano dry forest of eastern Bolivia, around Guayaquil (Ecuador) and in northern Colombia and Venezuela. Previously known as Turbina abutiloides (Kunth) O’Donell, this formerly recognised genus is now treated as a synonym of Ipomoea.

Leaves petiolate, 3–10 × 3–11 cm, broadly ovate, base truncate to subcordate, apex retuse, rounded or obtuse, adaxially pubescent, abaxially grey-tomentose; petioles (1–)3–6(–10) cm, pubescent to tomentose. Inflorescence of axillary and terminal cymes, the later compound and often paniculate or racemose in form, sometimes distinctly leafy; peduncles 2–11 cm, tomentose; bracteoles 2–9 mm, linear, tomentose, soon caducous; short (c. 5 mm), secondary and tertiary peduncles often present; pedicels 5–25 mm, tomentose; calyx narrow and ±cylindrical, sepals subequal, 10–14 × 4–7 mm, oblong-obovate, obtuse to rounded, drying brown, glabrous or nearly so, inner c. 2 mm longer than outer, the margins broad and scarious; corolla 5–7 cm long, funnel-shaped, pink, pubescent in bud, glabrescent, limb 4–5 cm, weakly lobed.
