Global description
Alysicarpus rugosus is an erect plant or spread on the ground, with simple oblong to lanceolate alternate leaves. The base of the petiole is framed by two lanceolate, papery and longitudinally strongly striated stipules, Inflorescences occur as clusters, composed of numerous pairs of orange and red flowers near each other. The sepals are interwoven and rounded at the base. Of the 10 stamens, 9 have their filaments fused in groove. The fruit is a pod, highly constricted between each of the 3-5 articles. These are suborbicular and have a highly transversely striated wall.Attributions | Wiktrop |

Northern Cameroon: Alysicarpus rugosus occurs throughout the crop cycle, but germination begins in June. Beyond this period, new emergences would occur after cultural operations (weeding and ridging) but remain very small. Flowering occurs from August to October and fruiting is staggered from September to November until the plant dries out at the beginning of the dry season. The complete development cycle is done in three months.
Madagascar : A. rugosus flowers during the rainy season from December to April.

A. rugosus is an annual species. It only propagate by seed. The seeds remain included in the articles of the pods and are spread by water, animals and wind.

This species is very difficult to differentiate from other Alysicarpus (A. ovalifolius, A. glumaceus) at the vegetative stage. Only the shape of the calyx, color of the flower and especially the shape of the fruit are used to identify with certainty.

Northern Cameroon: Alysicarpus rugosus occurs as a ruderal species and as a weed of crops. It grows mainly in the Sudanese region, where annual rainfall is between 1,200 and 1,500 mm. In this region, it is present in 30% of cultivated land. It grows on soil that retain moisture such as well-structured ferruginous soils and the planosols. It also appears, purposefully, in the driest regions on high water retention soil such as fersialitic soil or the vertisols. It can then be found in association with A. ovalifolius.
Madagascar: A. rugosus grows on alluvial soils, humiferous ferruginous soil, quite fertile, in sunny places or lightly shaded. It is a weed of crops in semi-intensive cropping systems based on corn and cotton. It grows in fallow, in degraded savannahs, on the edges of crops and roads in semi-arid and sub-humid until 1000 m of elevation, in the Southwest , West and Middle West regions of Madagascar.
