Epidendrum eustirum Anes, Hubbard & 
Schweinfurth nom. nov. 
Mpidendrum carinatum Lindley Fol. Orch, Epid. 
(1853) p. 61, nec Linnaeus (1753), nee Vahl (1793). 
Owing to the former use of carinatium as a specific 
name, f.carmatum Lindl. requires a new name. 
The new specific name eustirwm means well-keeled, 
in reference to the carinate sepals. 
Epidendrum glaucovirens Ames, Hubbard & 
Schwemfurth nom. nov. 
Prosthechea glauca’ Knowles & Westcott Floral 
Cab. 2 (1838) 111. 
Mpithecia glauca Knowles & Westcott Floral Cab. 
2 (1888) 167, t. 87. 
Lipidendrum glaucum Lindley in Bot. Reg. 26 
(1840) Mise. p. 29, non Swartz (1788). 
The specific combination J. e7aucum Lindl. is in- 
validated because of the earlier Z.g/aucum of Swartz.
