Native Orchids of Oklahoma

Abstract

As of the publication of this paper Oklahoma is known to have orchids of 33 species in 18 genera, which compares to 20 species and 11 genera reported by Waterfall (1969). Four of the 33 species are possibly extinct in the state based on current survey work. The greatest concentration of orchid species is in the southeastern corner of the state (Atoka, Bryan, Choctaw, LeFlore, McCurtain and Pushmataha Counties).
