Vegetative anatomy of Calypsoeae (Orchidaceae)

Vegetative anatomy of Calypsoeae (Orchidaceae)

Calypsoeae represent a small tribe of anatomically little-known orchids with a wide distribution in the Western Hemisphere. Leaves are present in all genera, except Corallorhiza and Wullschlaegelia both of which are subterranean taxa. Stomata are abaxial (ad- and abaxial in Aplectrum) and tetracytic...
