📚 Overview
Description
Cotyledons
The cotyledons are remarkable for their V-shaped, bilobed lamina, with narrow and slightly arched branches, 2.5 cm long and 2 mm wide. The lamina is carried by a petiole, 7 to 10 mm.
First leaves
The first leaves are alternate, simple and deeply cut into 3 or 5 segments, with highly serrated margins.
General habit
The plant is a vine that creeps on the floor or twines on neighboring plants. The plant is highly branched from the base. The principal axis are 50 to 90 cm long.
Underground system
The plant has a taproot system.
Stem
The stem is cylindrical and hollow. It is smooth and longitudinally striated. It is often twisted.
Leaf
The leaves are alternate and simple. They are held by a petiole of 8 to 20 mm long. The lamina is deeply divided into 5 palmate segments, obovate in shape. The median segment is greater than the lateral segments which carry a side segment of the outer side. Each segment is 2 to 3 cm long and 5-12 mm wide. The margin of the segments is strongly and irregularly serrated. Both sides of the leaf blade are glabrous. Five main veins emerges from the base of the leaf blade.
Inflorescence
The flowers are inserted in the axils of leaves, are solitary or grouped in 2 or 3 but are not enclosed in a leafy bract.
Flower
The flowers are held by pedicels, 7 mm long, at the tip of a peduncle, 2 to 5 cm long. The calyx consists of 5 elliptical sepals, 5 mm long and adorned with 3 warty longitudinal ridges. The corolla is white, campanulate, and slightly open at the top. It is 15 mm long and 10 to 13 mm wide.
Fruit
The fruits are slightly flattened spherical capsules. These capsules formed from 5 dehiscent valves, 10 to 12 mm in diameter and 6 mm high. They contain 5 seeds.
Seed
Seeds are trigonal. They are 4 mm long and 3 mm wide. The dorsal surface is rounded and the side faces are planar. The seed coat is dark gray, covered with a short pubescence.
Global description

Cyclicity
Northern Cameroon: Ipomoea coptica is observed throughout the rainy season. Germination takes place in early July and the first flowers appear in August. Fruiting occurs in September till drying of the plant early in the dry season. Cultivation operations are followed by few new seedlings.
Madagascar: I. coptica blooms as from the middle of the rainy season.

Ecology
Northern Cameroon: Ipomoea coptica is mainly a species of Sahelo-Sudanese region, where annual rainfall is between 600 and 800 mm. It is characteristic of sandy soil on the surface but with a perched water table such as ferruginous soils of dunes and sandy banks along the river.
Madagascar: The species grows on ferruginous soils more or less humiferous (temporary waterlogging), in natural pastures and abandoned fields. It is a weed of rainfed crops in semi-arid and low altitude sub-humid area of plains. It grows on fairly fertile soils, in sunny or lightly shaded land in cultivation systems of cotton or maize, semi-intensive of agro-ecological semi-arid zones (Southwest and West) and low altitude sub-humid areas (North-west plains).

Risk Statement
Madagascar: I. coptica is an infrequent species and often scarce. The control presents no particular difficulty in crops. It remains a scarce species, but rather characteristic of areas of semi-arid and sub-humid plains. It can interfere with harvesting operations in cotton cultivation
Local harmfulness
Northern Cameroon: Ipomoea coptica is an infrequent weed but can be locally abundant and is a good environmental indicator. It grows in low intensified cultures, receiving no or little fertilizer and no herbicide. It is also present in young fallows.Madagascar: I. coptica is an infrequent species and often scarce.
