Global description
Ipomoea alba is an annual or perennial, herbaceous, glabrous vine, with milky latex, and is 6 m long. The leaves are simple and alternate, long-stalked, heart-shaped with a wide base deeply indented and tapered acute apex. They are of two forms, either whole or cut into three lobes, both often present on the same plant. Flowers are axillary, solitary or in small groups, large, with the corolla having an elongated tube then very spread in wheel. The fruit is a pointed capsule containing 4 sub trigonal seeds.
Cotyledons
The cotyledons are long petiolate. The lamina is bilobed, diverging V-shaped very broad. It is wider than it is long, 3 to 4 cm long and 4 to 6 cm wide. Each lobe has a rounded or acute apex, the faces are glabrous and embossed. The base is deeply corded, the lobes joining together. From the base leave 5 main palmate veins.
General habit
Annual or perennial, herbaceous lianescent plant, glabrous, with the base more or less woody, and which can reach 5 to 6 meters in length. The stem contains a milky latex.
Underground system
The plant has a taproot system.
Stem
The stems and the branches are glabrous. Their surface is smooth or provided with small asperities which can be numerous. The stem produces a milky sap.
Leaf
The leaves are simple and alternate. The petiole measures 3 to 10 cm long, up to 16 cm. The leaf blade is thick, widely oval, cordiform deeply indented base, with acute acuminate apex. It measures 5 to 15 cm long (20 cm long) and 5 to 10 cm wide (up to 15 cm). Its margin is entire or trilobed. They are of two forms, either whole or cut into three lobes. The two types of leaves are often present on the same plant.
Inflorescence
The flowers are axillary, either isolated or grouped in small numbers on a contracted inflorescence with a stalk of 1 to 10 cm long (up to 18 cm).
Flower
The stalk measuring 1 to 2 cm long. Sepals are unequal: the external are elliptical (6 to 10 mm long, without their extension in point), terminating by a filiform elongate tip (5 to 9 mm long), the internal are subcircular (12 mm diameter) with triangular tip (3 to 4 mm long). The corolla is white and consists of a tapered tube (7 to 12 cm long and 5 to 6 mm in diameter) and a wheel-shaped lamina, 5-lobed (8 to 10 cm diameter) . The flowers open very quickly, at the dusk. The 5 stamens, with slender filaments, are inserted in the upper 1/3 of the tube of the corolla and are external. The ovary is conical and glabrous, with a long filiform stigma, ending by an external stigma.
Fruit
The fruit is an ovoid capsule, 20 to 25 mm in diameter, ending in a point, supported by a thickened pedicel. The calyx is persistent, and continues to grow after fertilization. The fruit contains 4 seeds.
Seed
Seeds are subtrigonal, 10 to 12 mm long and 7-9 mm wide. They are glabrous or contains small scattered applied hairs.

Madagascar: Ipomoea alba grows on alluvial soils along river edges and canals, on the edge of the forests and along the cultures. It is rarely a weed of crops. It is present in areas of low altitude on fairly rich soil, in more or less shaded conditions.
Mauritius: Species mainly present in abandoned areas at the edge of rivers, where it invades and covers the surrounding vegetation.
Mayotte: I. alba is an exotic species commonly naturalized in secondarized environments of hygrophilous and mesophilous regions. It grows in crops, villages, along roadsides, in ditches and in agroforests.
Reunion: Ipomoea alba was introduced as an ornamental plant ; it is now naturalized in several places in the island. Ipomoea alba is present in hedges and edges of forest areas.Until now, this species does not behave as a weed of crops.
