Nomenclatural notes on some Russian orchids
The name Neottia camtschatea was originally validly published by Sprengel in 1826, not by Reichenbach in 1851 as is widely accepted. The name Ephippianthus schmidtii antedates (Reichenbach, II 1868) the name E. sachalinensis (Reichenbach, VI-X 1868) though the latter, being illegitimate as nomenclaturally superfluous, is more frequently used and accepted in international databases. Errors in type citation of the names of two forms of Listera cordata described by V. N. Vassiljev, f. tenuis and f. crassa, are corrected. Two names in new rank, Platanthera chorisiana subsp. elata (Finet) Efimov and Epipactis subgen. Arthrochilium (Irmisch) Efimov, are published.
