Diodia (or Buttonweed) is a genus of flowering plants in the Rubiaceae family. It was described by Carl Linnaeus in 1753. The genus is found from southern and eastern United States, South America, Central America, Mexico, the West Indies and tropical Africa.
Many species of Diodia have been transferred to a closely related genus Diodella, and therefore the name Buttonweed also applies to these species. There are also many species of False Buttonweeds in the related genus Spermacoce. The Velvetleaf Abutilon (Abutilon theophrasti) in the family Malvaceae is also known by the common name of Buttonweed.
