North America, Mexico, West Indies, Central America, South America, Asia (Malesia), Africa, Australia.
Discussion
Species ca. 100 (3 in the flora).
In some publications, the honoree of the name Buchnera is given as Johann Gottfried Büchner (1695–1749), German botanist. C. Linnaeus (1738) explicitly stated that the honoree is A. E. von Büchner. Linnaeus omitted this information in 1753 and 1754, thus perhaps opening the door to erroneous etymology.
