Spermacoce alata, the winged false buttonweed, [2] is a species of plant in the Rubiaceae. [3] It is widespread across the warmer parts of the Western Hemisphere and naturalized in many other parts of the world.

Description

Spermacoce alata is a perennial herb, sometimes erect but other times decumbent. Stems are square in cross-section, with wings along the corners running lengthwise along the stem. Leaves are elliptical to oblong, up to 8 cm long. Flowers are white to very pale purple, formed in axillary clumps. [4]

Distribution

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.
