Spermacoce alata is considered native to southern Mexico, Central America, a few islands in the Caribbean (Trinidad and the Leeward Islands), and parts of South America (French Guiana, Suriname, Guyana, Venezuela, Colombia, Ecuador, Peru, Brazil, Paraguay and Argentina). It is reportedly naturalized in tropical Africa (from Liberia to Uganda), China (Fujian, Guangdong, Hainan, Taiwan, Zhejiang), India, Nepal, Sri Lanka, Bangladesh, the Andaman & Nicobar Islands, Malaysia, Thailand, Borneo, Java, Myanmar (Burma), Sumatra, Queensland, the (Australian) Northern Territory, Fiji and Samoa.[1][4]
