It will be observed that I have followed all the recent British 

 and most continental authorities in keeping distinct the two genera 

 Cephalaiithcra and Helleborine {Epipactis R, Br. not Boehmer), 

 thus differing from A. A. Eaton (Proc. Biol, Soc. Washington 21 : 

 63-68. 21 Mr 1908), who follows Wettstein in uniting them. 



Mr. Eaton is quite correct in stating that Linnaeus' genus Se- 

 rapias is composite — so too are his species. But since Hill in 

 1756 first separated Helleborine ^xova that composite genus, leaving 

 Serapias as understood by Sw^artz, and restored the name which 

 for centuries previously had been used, his genus has priority ac- 

 cording to the Vienna Rules, Hill's genus, it \s true, included 

 Cephalanthera^ subsequently separated by Richard ; but even if 

 Wettstein be correct in uniting them, the application of the name
