Preliminary evidence for limited hybridization among Midwestern Spiranthes (Orchidaceae).

Spiranthes (ladies’ tresses orchids) is a genus of ca. 32 primarily North American species in which hybridization is though to be extremely common. Hybridization is hypothesized to be especially pervasive within the ‘Spiranthes cernua complex’ sensu Sheviak though there has been no phylogenetic evidence to support this view. Preliminary phylogenetic analyses of multiple nuclear and plastid loci provide evidence for geographically widespread but infrequent hybridization events between Spiranthes cernua and Spiranthes magnicamporum.
