Environment

Common as a pioneer in newly opened up habitats along roadsides, edges of forests, re-growths, thickets, and in young secondary vegetation, from sea-level up to 1200 m. Fl. fr. Jan.-Dec. At least in Malaya pollination is affected by wind and by small insects (diptera). Ripe fruits are dispersed by various species of bulbuls.
More
Sunny moist forests, scrub on sunny slopes, riversides and open places at elevations of 100-1,100 metres in southern China.
Grows in lowland and upland rainforest on a variety of sites; from near sea level to 950 m alt. Favours disturbance.
