Description.
Low trailing or twining herb with slender stems, pubescent in all parts, rootstock a carrot-shaped tuber. Leaves petiolate, 2-6 (-8) × 2-6(-9) cm, ovate, with sinuate margins or, usually 3-5-lobed to near base, lobes oblong-elliptic, narrowed at both ends, acute, shortly mucronate, laterals sometimes shallowly lobed near base, base cordate with rounded auricles, both surfaces densely pubescent; petioles 1-2(-5) cm, pubescent. Inflorescence of solitary or, occasionally paired, axillary flowers; peduncles 1-4 cm, pubescent; bracteoles 4-8 mm long, linear, persistent, pubescent; pedicels 2-10 mm, pubescent; sepals unequal, grey-pubescent or pilose, outer 12-21 × 6-10 mm, ovate, acuminate, base cordate, inner lanceolate, 2-4 mm wide; corolla 4-5 cm long, funnel-shaped, glabrous, tube flushed reddish, limb purplish, c. 2 cm diam., unlobed but midpetaline bands terminating in a tooth. Capsules subglobose, 8-12 mm long, glabrous, enclosed by sepals, 3-locular, up to 6-seeded; seeds 4-6 mm long, minutely tomentellous.

Distribution.
Amphitropical in its distribution occurring in the United States and Mexico and along the Andes from Peru south to northern Argentina with an isolated station in central Colombia. It is locally common in dry stony grassland between 2300 and 3900 m, reaching higher altitudes than by any other Ipomoea species except I. plummerae .

Typification.
The lectotype of Ipomoea papiru was wrongly cited and is, therefore, corrected above.
Notes.
A usually very distinct species on account of its deeply-lobed, hirsute leaves and ovate, basally cordate, outer sepals. Rare entire-leaved forms occur, for example Wood 17697 from Bolivia. Some specimens from the Chihuahua desert are intermediate with I. lindheimeri .
The root is eaten fide Gutiérrez-R (2016).
