Global description
Chloris barbata is a grass growing in diffused tufts. The stems are erect and geniculate at the base. The leaves are smooth with a linear lamina and acute at the top. The sheath is smooth with few long stiff hairs at the top. The ligule is very small. The inflorescence is formed OF 5 to 15 erect spikes. They are arranged on top of the stem, as glove fingers. The spikelets are purple violet in color and are protruded by long bristles.
General habit
Annual herb growing in diffuse tufts, 30 to 75 cm high. It is sometimes stoloniferous.
Underground system
The roots are fibrous, at the base of the plant, but can develop from the nodes of stolons.
Culm
The grass culm is elliptical between nodes, hollow, compressed at the base. It is erect or geniculate and ascending, with glabrous node.
Leaf
The leaves are alternate. The sheath is glabrous or with a few long stiff hairs at the top. The ligule is short, 0.5 mm, membrane ciliated. The lamina is linear, flat or partially folded, with an acute apex. It can measure up to 40 cm long and 3 to 6 mm wide. The faces are smooth to loosely hairy, the margin is finely scabrous.
Inflorescence
The inflorescence is composed of 5 to 15 digitate erect racemes, they are placed on top of the floral axis, like glove fingers. Racemes measure 3 to 8 cm long, they are purple in color, more or less stocky or flexuous. The rachis have scabrous angles.
Flower
The spikelets are subsessile, laterally compressed, 2.5 mm long, with 3 flowers and 3 edges. The lower glume is lanceolate, membranous, uninervate with scabrous hull. The upper hull is rounded at the top. They measure 1.7 to 2.5 mm. The internal flower is fertile. The elliptical trinervate lemma, is extended by an edge of 4.5 to 7 mm long, barbed. The two external flowers are sterile, shorter and truncated. Lemmas are widened and surmounted by a long barbed edge of 2.5 to 7 mm.
Grain
The grain is oblong elliptical, 1.3 to 1.5 mm long, light brown in color.

French Guiana: Chloris barbata is a heliophilic species common to gardens and wastelands; it can also be found on the dikes of the Mana rice polder.
Madagascar: C. barbata is a ruderal plant colonizing roadsides and locations near homes and weed of rainfed crops on light relatively fertile soils (alluvial soils and ferruginous soils or down slope). Its range is limited to the wetland and sub-humid Northwest of the island.
Mauritius: Ruderal species, growing on roadsides. It is fairly common.
Mayotte: Chloris barbata is an exotic anthropophilic species, very commonly naturalized in degraded areas of a wide range of environments. It grows as well on sands as in clayey ditches of wetlands, it is present in gardens, crops, pastures and roadside banks.
Reunion: This species grows up to 800 m altitude in the windy region and up to 1000 m altitude in the downwind area. It is not very demanding and also grows as well on fertile alluvial as on sands.
Seychelles: Species occurring on road edge and unoccupied land. It is rarely abundant.
West Indies: Chloris barbata is an exotic species. It is a heliophilous species frequent along roadsides, in fallows and fallow lands. It is not very demanding in terms of soil quality and is more abundant on sandy and stony soils. It tends to disappear from damp and shady areas.

Local harmfulness
French Guiana: Species occasionally observed in fruit plots or in recent places where the forest has been slashed, never abundant.
Madagascar: Chloris barbata is a species relatively infrequent and often scarce in rainfed crops.
Mauritius: A weed rarely found in crops, low harmfulness.
Reunion: C. barbata is essentially a forage grass. It rarely gets into sugarcane fields. It is found as a ruderal species along roads, near houses and in fallow. It sometimes infests the edges of vegetable cultivation.
Seychelles: A weed of low harmfulness.
West Indies: Chloris barbata is a weed present in all crops except shaded banana plantations. It is not very harmful to sugarcane, fruit and vegetable crops. It is very frequent in orchards because mechanical weeding easily favours its establishment without affecting the development of the trees. It participates in the formation of a spontaneous plant cover by cohabiting easily with other grasses.
