Ipomoea rubens Choisy

A perennial hairy twiner. Stems terete, densely short-pilose with soft whitish hairs. Leaves broadly ovate to orbicular, 5-15 by 4-12 cm, broadly cordate at the base, acuminate at the apex with an acute or obtuse mucronulate point, densely pilose beneath, much more sparsely so and glabrescent above; nerves 7-9 on either side of the midrib; petiole slender, 3-12 cm, pilose like the stem. Inflorescences axillary; peduncle terete, 2-14 cm long, pilose like the stem, often glabrous or nearly so in the basal portion, cymosely one-to few-flowered with very short branches; flowers consequently subumbellate. Pedicels pilose, mostly longer than the calyx, ¾-1½ cm, in fruit up to 2 cm. Sepals equal in length, ¾-1 cm, the 2 outer ones elliptic-oblong, acute, shortly pilose, the inner ones broader, ovate-elliptic, less acute. Corolla pink or purple with a darker centre, funnel-shaped, 4-5 cm long, with sericeous hairs on the midpetaline bands outside. Stamens and style included. Filaments hairy at the flattened base. Ovary glabrous. Capsule globose, 12 mm diam., glabrous, 2-celled, 4-vaived. Seeds 4, ca 6 mm long, white-villous.

In marshes, along rivers, and in marshy forests, occasionally in waste places, up to 1000 m.
