The genus Eulophus of Brown is a large group of orchids native 

 of the tropics of the Old World. It has been generally written 

 Eulophia (R. Br. Bot. Reg. t. 686. 1823), which was merely a change 

 of spelling from the original publication in 1821. 



The American species of Eulophus Nuttall, should therefore be 

 placed in the genus Perideridia of Reichenbach, based upon Eulophus 

 americanus of Nuttall.

 The type of Gregoria (G. vitaliana Duby, I.e.) native of the

 tofore designated as Douglasia, and indeed was transferred to Doug-
