Habitat and Ecology [top]

Habitat and Ecology:The species is considered a moderately common weed of sugarcane fields, roadsides, open grasslands, and the seashore, reported from elevations between sea level and about 800 m in Fiji (Smith 1979). It has been occasionally found in waste places and lawns (Whistler 1988), cultivated ground or lawns in Guam (Stone 1970), off roadsides, gardens and annual field crops, often invading heavily-grazed pastures and hindering the re-establishment of better grasses from low altitudes to about 1,200 m  in New Guinea (Henty and Pritchard 1973), and on hillsides and damp ground, especially in areas of cultivation and irrigation in the Arabian Peninsula (Cope 2007).
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: In action the rhizomes are diuretic and its pastes are taken in kidney problems. This is a weed of agricultural fields and sometimes used as fodder.
