Distribution About 150 species from the southern U.S. and Mexico to Argentina and Chile; predominantly northwestern South American. A comprehensive treatment of the genus is needed and will ultimately be provided by Ferreyra (for Peru see Jour. Arnold Arb. 27: 123-167, 1946; for Ecuador see Lloydia 16: 193-226, 1953; for Colombia see Smithsonian Misc. Coll. 121: 1-59, 1953; for Vene- zuela see Brittonia 9: 9-18, 1957). Two species are recognized for Panama.
