📚 Overview
Description
Global description
Desmodium ramosissimum is a sub-shrub, quite branched from the base, 10 to 150 cm high. The branches have dense appressed pubescence, but without little hairs ending with hook. The leaves are alternate, compound trifoliate. The lateral leaflets are oblong-elliptic to ovate. The terminal leaflets are rounded obovate to slightly notched, mucronate at the top. They are glabrous above and finely appressed pubescent below. The flowers are pink to purple, arranged along an inflorescence in terminal or axillary raceme. The fruits are pods, 15 to 20 mm long, consisting of 4 to 6 rounded, pubescent articles.
General habit
Sub-shrub, rather branched from the base, 10 to 150 cm tall; the branches have a dense appressed pubescence, but without little hairs ending in hook.
Underground system
Taproot system.
Stem
The stem is cylindrical and full, more or less woody at the base, branched, with pubescent branches with appressed hairs.
Leaf
The leaves are alternate, compound with 3 leaflets, petiole 10 to 15 mm long, pubescent. The stipules are oblique, narrowly ovate-triangular attenuated, 4 to 8 mm long. The terminal leaflet is obovate rounded to emarginate and mucronate at the top, 8 to 25 mm long and 4 to 10 mm wide, the upper face is glabrous and the underside is pubescent with appressed hairs sometimes dense; lateral leaflets are smaller and oblong-elliptic.
Inflorescence
The inflorescences are terminal or axillary, loose racemes, 5 to 15 cm long.
Flower
The flowers are solitary or in pairs, carried by a pedicel, 4 to 10 mm long, pubescent; the calyx, 2 to 3 mm long, is fused at the base and divided into narrow lobes longer than the pubescent tube; the corolla is pink or purple in color, 3.5 to 5 mm long, with more or less veined petals; the stamens are fused into a beam of 9 stamens forming a sleeve 3 mm long, plus 1 free stamen.
Fruit
The fruits are articulated, sessile pods, 15 to 20 mm long, covered with a pubescence of straight appressed hairs, almost rectilinear from the top side and deeply indented into 4 to 6 more or less rounded articles on the lower side, indehiscent and each containing a seed, 4 mm long and 3 mm wide.
Seed
Seeds are kidney-shaped, 2.5 to 3 mm long and 1.5 to 2 mm wide, smooth, brownish orange in color.

Cyclicity
Desmodium ramosissimum is a perennial species that reproduces by seeds. The articles of the fruit, each containing a seed, are spread by animals, wind and water.

Ecology
Madagascar: Desmodium ramosissimum grows on alluvial soils, coastal sands, ferralitic soils and ferruginous more or less humus soils, of average to low fertility, in sunny places. It is a weed of crops and fallows, edges of crops and roads, disturbed sites and around homes in areas of the Highlands and sub-humid areas (Middle East, North West and West) and wet (East and Sambirano) . It is found in the farming systems of cassava or fruit crops, more or less extensive.
Mayotte: D. ramosissimum is a native species that grows in natural wetlands, such as resurgences on mountainsides or freshwater swamps, and ditches.
Reunion: Species present on recent lavas of the coast in very humid area and in the grass lawns and uncultivated land.

Local harmfulness
Madagascar: Desmodium ramosissimum is a weed quite common and usually slightly abundant in crops in dry stations of humid areas and in fairly humid lowlands in sub-humid areas. It is a woody species rather difficult to remove by simple means once it has been properly spread. It can be locally abundant in long cycle cassava crops in fruit crops and the edges of slash and burn cultivations.
