Old World tropics, including South-East Asia; probably introduced into the Americas.
In India and Indonesia used as green manure mainly in rice fields but also in tea plantations. Its wood ("sola wood") has a specific gravity of 0.04 and is the lightest wood known; it is sometimes wrongly considered as pith; it is used for handicraft, but is inferior to that of A. aspera L. A. indica is moderately palatable as a forage, even after plants have died, but it has been suspected of being toxic. It occasionally causes weed problems e.g. in Australia and India.
- Erect, branched, shrubby, annual herb, 0.5-2.5 m tall, glabrous. Stem hollow, at the base warty with stem nodules and coated with white aerenchyma.
- Leaves pinnate; stipules 6-7 mm long, extending below the leaf; rachis 5-7 cm long; leaflets 17-71, very close together, 3-15 mm × 1-4 mm, asymmetrical at base.
- Inflorescence an axillary raceme, 1-6-flowered, 2-5 cm long.
- Calyx with shortly bifid upper lip, shortly trifid lower lip; standard 7-9 mm × 4-7 mm, yellow with purple streaks or patches.
- Pod stalked, 2.5-5 cm × 0.4 cm, 5-13-jointed.
- Seed reniform, 2-3 mm long, brownish.
A. indica occurs mostly in wet sites, seasonally flooded or waterlogged grasslands, swamp margins, also on alkaline or saline heavy clay soils, up to 1000(-1600) m altitude. It forms aerial nodules on the stem with specialized Rhizobium spp. If its habitat is not waterlogged, the plant symbioses with vesicular-arbuscular mycorrhizal fungi and nodulates with Rhizobium spp.
