Spermacoce (or False Buttonweed) is a genus of flowering plants in the Rubiaceae family. It comprises about 275 species found throughout the tropics and subtropics.[1] Its highest diversity is found in the Americas, followed by Africa, Australia and Asia.
Description[edit]
The species are herbs or small shrubs with small- to medium-sized, four-lobed flowers arranged in capitate inflorescences. Some have a brightly coloured calyx and are eye-catching, particularly the Australian species. The corolla is variable in colour, often white, but also all shades of blue, pink and maroon. The fruit is usually a two-seeded capsule, sometimes a schizocarp or nut.[2]
