Type

Type: plant cultivated in Vienna, probably not preserved.

Morphology General Habit

Vigorous creeping or climbing perennial, stems somewhat woody, winged when old, glabrous

Morphology Leaves

Leaves petiolate, 5 – 14 × 6 – 16 cm, 5-lobed to about two thirds, base shallowly cordate to truncate and cuneate onto the petiole, lobes elliptic, narrowed at both ends, apex obtuse, both surfaces glabrous, abaxially paler; petioles 2 – 6 cm, usually glabrous

Morphology Reproductive morphology Inflorescences

Inflorescence of pedunculate axillary, occasionally compound cymes; peduncles 3 – 13 cm, glabrous or puberulent; bracteoles 6 mm, linear, caducous; secondary peduncles (if present), 5 – 15 mm; pedicels 5 – 22 mm, puberulent; calyx subglobose; sepals slightly unequal, elliptic, concave, coriaceous with a very narrow scarious margin, glabrous or puberulent near base, 7 – 10 × 5 – 6 mm, the outer obtuse, the inner rounded; corolla 5 – 6 cm, inflated above a narrow basal tube, pink, glabrous, limb c. 3 cm diam. Capsule 10 – 15 × 6 – 10 mm, ovoid, glabrous; seeds 6 mm long, lanate.

Ecology

Pantropical in distribution but preferring the humid tropics in equatorial regions. In Bolivia apparently a rare species of the Pantanal and Amazonian lowlands.

Conservation

Not evaluated (NE). A very widespread pantropical species.

Note

It appears to flower in the summer rainy season from December to March.

Ipomoea mauritiana is a very variable plant, particularly in the Old World where forms with unlobed leaves are reported. It is somewhat unsatisfactorily distinguished from I. cheirophylla and similar species. It is a plant of humid tropical lowlands and the leaves are larger than in related species and the inflorescence is only sometimes compound.
