 Not only was Rafinesque the first— be was for a long time tlie 

 only botanist to declare this a distinctly generic type ; for 

 Nuttall made of it no more than a named subgenus of 

 Malaxis; and Elliott went no farther. But Amos Eaton 

 who, in 18'22, called it a genus Microsirjlis, was the first after 

 Rafinesque to pronounce it positively a genus. Lindley, and 

 a little before him Blume (as Crepidium), gave to it that con- 

 firmation by virtue of which it has ever since held place among 

 the most unquestioned of orchideous genera. It was unfor- 

 tunate that Lindley did not go back to the original Rafin- 

 esquian and altogether excellent name. Only the following 

 United States and Mexican species are well known to the 

 present writer.
