Global description
Ipomoea eriocarpa is a twining species with simple alternate leaves. The cotyledons are bi-lobed. The stem and the petioles are covered with reflected hairs. The leaves are cordate at the bottom and acute at the apex, in the heart more or less elongate. The flowers are small, bell-shaped, white or purple in colour and assembled in groups on the axils of leaves. The fruits are globular pubescent capsules. The seeds are glabrous.Attributions | Wiktrop |

Northern-Cameroon: Ipomoea eriocarpa is observed throughout the rainy season. Its germination is possible from the first rains of May until the last rains of November. This plasticity gives it the assurance to reproduce every year. The germinative phase is not affected by cultural operations (ploughing, weeding, ridging). The period of maximum germination is between July and September at the time of the heaviest rains. I. eriocarpa is a species whose flowering is induced by the shortening of the photoperiod. Whatever the technical itinerary, flowering starts in October, followed 2 or 3 weeks later by fruiting. Also the complete reproductive cycle of this species varies from 20 weeks for early emergence in May to 4 weeks for late emergence in October. Early cycle weeding techniques, whether chemical or mechanical, protect the crop temporarily but do not prevent the development and reproduction of species such as I. eriocarpa at the end of the cycle.
Mayotte: Ipomoea eriocarpa flowers from May to August and fruits from June to September.

Ipomoea eriocarpa is an annual species. It multiplies only by seed. Seed germination is greatly enhanced by their transit through the digestive tracts of cattle.

Ipomoea purpurea and Ipomoea indica can be easily confused. Ipomoea purpurea is a vine not exceeding 4 m long, with generally entire leaves (unlobed), but rarely lobed, inflorescences usually containing 1 flower sometimes up to 4, the corolla of which is 4 to 5 cm long with color more often pastel (pink, blue, purple), while Ipomoea indica is a large liana that can easily reach 10 m long, has leaves of variable form often trilobed, dense inflorescences always containing several flowers and often more than 4, with corolla 5 to 7 cm long and of intense blue or violet color.

Northern Cameroon: Ipomoea eriocarpa is a weed extremely common and generally abundant in all annual crops, from the Sahelo-Sudanese regions to Sudanese regions. This species is ubiquitous and grows on any soil type. Seed germination is related to their passage through the digestive tract of ruminants, this species is particularly frequent and abundant in livestock areas or where cattle manure is used as amendment plots.
Comoros: absent.
Madagascar: Very common species in rainfed regions of sub-humid and semi-arid Madagascar (Middle-East, West and Southwest). This is an undemanding species that can infest all dry crops on different soil types.
Mauritius: absent.
Mayotte: Ipomoea eriocarpa is a rather rare indigenous species which grows in secondarized environments.
Reunion: This species is ubiquitous and grows on any soil type, preferably at low altitude.
Seychelles: absent.
