Geographic Range [top]

Range Description:The species occurs throughout tropical and subtropical regions of the world, but is apparently largely absent from temperate and Mediterranean regions; reports of its presence in Europe and Russia are not reliable. It occurs throughout most of Africa south of the Sahara and Egypt, throughout the Middle East, east through the Indian subcontinent, most Indian Ocean island groups, East and Southeast Asia from the People's Democratic Republic of Korea south through Japan, China, Myanmar and Viet Nam to Malaysia. It also occurs in Indonesia, Papua New Guinea, Australia, Philippines and New Zealand. It is reported as native to some of the Pacific Ocean island groups and as introduced to others. In the Western Hemisphere it is non-native in the southern United States and of uncertain origin through Central America and the Caribbean south through much of South America to Chile and Argentina. It has also been naturalized in northern and eastern parts of Spain.

Population [top]

Population:This species has a huge global range including both native and introduced distribution. It is probably no longer possible to be certain of its native range and consequently whether there may be different trends in native and introduced populations. However, it is extremely abundant and increasing in many areas, to the extent that it is widely considered a weed.
Current Population Trend:Increasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a pioneer or ruderal species typically growing on disturbed parts of a variety of wetland habitats, often in species-rich associations with a range of other aquatic and wetland plants. It grows in the draw-down zones of water bodies or in water up to 1 m deep, where it may be part floating and part emergent or even grow in mats of floating vegetation. It is a typical plant of the floodplain wetlands, margins of rivers, streams, canals, ditches, ponds, reservoirs, tanks (in India). It will also grow in marshes, swamps, wet low-lying ground, ephemeral pools, seasonal pans and damp forest. It is a typical species of anthropogenic wetland habitats, such as damp areas in abandoned cultivation particularly in wet headlands, fallow rice fields, in seasonally waterlogged roadside depressions, on damp tracks and around villages, plantations, waste ground and even gardens. It will also grow in relatively dry situations on ditch banks or in cultivated crops. In Nigeria it is a weed of maize crops and in the Democratic Republic of the Congo it has been recorded growing in fields with sorghum, millet, Eleusine spp., maize, cotton, cassava, groundnuts and other cash crops. In the Philippines it occurs with tobacco, dry land field crops, pastures, and vegetable farms. It will grow on a range of soil types from poor sandy or alkaline soils, to loam or black cotton soils. It may extend into brackish water and estuarine habitats near the coast.
Systems:Freshwater

Use and Trade [top]

Use and Trade: It is eaten as a vegetable and cultivated as such. It is also used in medicine (Cook 1996, Larsen 1992) being used to treat diarrhoea, dysentery and fevers. The leaves, flowers and tender stems are used as a vegetable in Karnataka. Juice of this plant, deemed beneficial to eyes, is an ingredient in the making of medicinal hair oils and Kajal (kohl). The red variety of this plant is a common garden hedging plant, which is also used as a culinary vegetable. Young shoots and leaves of the weed are harvested as vegetables in Malaysia, Sri Lanka, Indonesia, the Philippines and Indo-China. It also serves as good ground cover and fodder. Medicated lotions may also be produced from A. sessilis for treatment of beri-beri and fever, and infusions of the weed can be taken internally for fever and inflammation of the intestines (Burkill 1966, Soewardi et al. 1982, Pancho and Obien 1983, CABI).

Threats [top]

Major Threat(s): A. sessilis is a weed of cultivated and waste ground. It is probably increasing both in range and abundance and is not subject to any known threats.
