 adopted at the Vienna Botanical Congress, is the name of the 

 genus commonly called Zeuxine. 



Adenostyles Cass (Bull. Soc. Philom. 1816) is a genus of the 

 Composite, but has no power to eliminate Adenostylis, as the last 

 clause of Article 57 of the Vienna Code provides for the retention 

 of generic names when the difference in spelling lies in the ter- 

 mination, even though the termination differs by one letter only.

 spelling by one letter in or near the middle, and in such cases it
