ORCHIDACE.E 



Rich. According to geographical distribution the species of Ery- 

 throdes as understood by Dr. R. Schlechter are confined to the 

 eastern hemisphere and are in part distinguished by the bilobed 

 sac or spur of the labellum. Physurus L. C. Rich, in Mem. Mus. 

 Par. 4 : 55 (1815) is a nomen nudum, consequently the name Ery- 

 throdes must be adopted for the genus. If Schlechter's views 

 are upheld and we regard a bilobed spur in connection with 

 geographical distribution sufficient characterization for a genus, 

 then it becomes necessary to make nomenclatorial changes. But 

 it seems best to assign to Erythrodes all the species that have 

 been valid under Physurus, and to disregard the segregation pro- 

 posed by Schlechter.
