This species is native to tropical America and has a wide distribution throughout tropical and warm temperate regions, growing along roads, alluvial plains, and field margins. It is distinguished from B. elegans by having a peduncle less than one cm, and from B. diffusa by its obconical fruit. The population of this species is increasing in southern Iran. Because of its remarkable ability to adapt to various climates, it is likely to colonize most regions affected by human activities.
