Description.

Twining annual herb, young stems glabrous, older stems setose. Leaves petiolate, 4-9 × 3-5 cm, narrowly (to broadly) deltoid, base sagittate to hastate, auricles acute to obtuse, glabrous, abaxially paler; petioles 2-7.5 cm. Inflorescence of 1(-2)-flowered axillary, pedunculate cyme; peduncles 0.5-3.5 cm; bracteoles 8-15 × 3-5 mm, ovate, acuminate to apiculate, membranous, pale green, moderately persistent; pedicels 1-2.5 cm; outer sepals 13-20 × 7-10 mm, ovate, apex finely mucronate, base truncate, abaxially 3-winged, the wings smooth or (especially below) dentate, inner sepals c. 5 mm shorter, unwinged; corolla 2.5-3.5 cm long, funnel-shaped, pink, glabrous, limb c.5 cm diam., shallowly lobed, the lobes acute. Capsules 12-15 × 12-14 mm, ovoid, glabrous, enclosed by the sepals; seeds 5-6 mm long, minutely tomentellous.

Distribution.

Pantropical in distribution but scattered in occurrence, the populations usually small and impermanent, growing in lowland areas besides lakes, ponds and similar disturbed moist habitats; perhaps most common in the New World around the fringes of the Chaco and in the Llanos of Colombia and noticeably less common in Central America and Mexico.

PUERTO RICO. Type of Ipomoea rubra var. palustris .

Typification.

Deroin suggested that Bosser and Heine had lectotypified Ipomoea fimbriosepala with the Lindley collection at CGE. However, they merely cited the collection under the acronym CAM.

The type material of I. assumptionis may be a mixed collection with I. setifera but the holotype at NY looks unmistakeably to be I. fimbriosepala .

Note.

This species is similar to Ipomoea setifera in having sepals in which the veins are extended into wings, these commonly dentate; also in the relatively persistent, pale green membranous sepals but differing in being annual, the bracteoles narrower, the sepals only 3-winged and the corolla much shorter. Fruiting specimens can be difficult to distinguish and the two species are commonly misidentified.
