Conservation
Least concern (LC).
Ecology
A pantropical species originally described from India but with every appearance of being native in Bolivia although molecular studies suggest an Old World origin. In Bolivia widespread but scattered in the eastern lowlands below about 350 m but restricted to the Amazon watershed apart from records from the Pantanal. It is a plant with a very distinct ecology, growing beside slow-moving tropical rivers, streams and small lakes.
Morphology General Habit
Twining perennial herb, stems tomentose, to several metres high
Morphology Leaves
Leaves petiolate, 4 – 8 × 3 – 5 cm, ovate-deltoid, often shallowly 3-lobed, cordate with rounded auricles, apex acute, adaxially pubescent, abaxially grey-tomentose; petioles 2 – 4 cm, grey-tomentose
Morphology Reproductive morphology Inflorescences
Inflorescence of compact, axillary, pedunculate cymes; peduncles 3 – 12 cm, densely woolly-pilose; bracteoles 3 – 7 mm, linear, caducous; secondary peduncles (if present) 2 – 3 mm; pedicels 5 – 17 mm, pilose; sepals somewhat unequal, outer (8 –) 10 – 14 mm, accrescent to 16 mm in fruit, ovate-deltoid, acute (or obtuse), pilose, inner sepals 8 – 12 mm, obtuse, pilose, margins scarious; corolla 4 – 5.5 cm, funnel-shaped, pink, sericeous-pubescent, limb 4 – 5 cm diam. Capsule globose, 8 – 13 × 11 – 12 mm, enclosed by sepals, glabrous; seeds 5 – 6 mm long, pilose.
Note
In designating a lectotype we have chosen the best of three sheets at Geneva, where Choisy worked.

It has been found in flower in nearly every month of the year.

The pilose sepals and grey-tomentose leaves can lead to confusion with Ipomoea longibarbis but the corolla is shorter and the bracteoles much smaller. Moreover their habitats are quite different, I. rubens growing by water whereas I. longibarbis is a plant of very dry scrub.

Type
Type: India, Wallich 1421 (lectotype G 00227258, designated here, isolectotypes G, K-W).
