It is difficult to understand why this plant was treated as a 
member of the genus Physurus or Erythrodes by former stu- 
dents of orchidology. The plants have neither rhizome nor 
cauline leaves, nor have the lips a distinct spur. An examina- 
tion of the type undoubtedly places it in the genus Eltroplectris, 
and its closest relative is another Brazilian species, namely, E. 
longicornu (Cogn.) Pabst.
