NOMENCLATORIAL STUDIES IN THREE ORCHID 



GENERA.* 



BY A. A. EATON. 



During the course of nomenclatorial studies in the Orchid- 

 acese I have found the following changes necessary in order to 

 conform with the articles of the Vienna Code. These changes 

 will he more fully discussed and a full bibliography given, with 

 synonomy and keys to the genera, in Orchidaceae, fascicle 3, now 

 ready for the press. 



EPIPACTIS (Haller) Bohmer. 



The name Epipactis appears to have been first used since 1753 by Bohmer 

 in the third edition of Ludwig's Definitiones Generum Plantarum. 

 Although he makes no binomial combination, his genus is properly made 

 and he gives several references to the plant designated by Linnaeus as 

 Satyrium repens, now known as Goodyera repens R. Br., or Peramium 

 repens Salisb. As the name Epipactis antedates all others for the group it 

 must be adopted. The resulting changes in specific names are as follows: 



E. angustifolia (Schlechter). 



Goodyera angustifolia Schlechter in Schumann & Lauterbach Nachtr. 

 Fl. Siidsee92 (1905). 



E. bifida (Bl.). 



Neottia bifida Blume Bijdr. 408 (1825). — Goodyera bifida Blume Fl. 

 Java Orch. 33, t. 9 | c, f. 1 (1858). 



E. biflora (Hook. f.). 



Goodyera biflora Hooker f. Fl. Brit. Ind. 6: 114 (1890). 

 E. brachiorrhynchos (Schlechter).
