Epidendrum subsect. Carinata Rchb.f. (1861) là một subsection of the section E. sect. Schistochila Rchb.f. (1861) of the subgenus E. subg. Amphiglottium Lindl. (1841) of the genus Epidendrum of the Orchidaceae (orchid family). This subsection differs from the subsection E. subsect. Integra in that the margins of the trilobate lip are dentate or lacerate. This subsection differes from the subsection E. subsect. Tuberculata by possessing a keel or carina on the midlobe of the lip. In 1861, Reichenbach listed nine species in this subsection.[1]

E. puniceoluteum was placed in E. subsect. Carinata in its publication as a new species in 2007.[4]
E. denticulatum was also acknowledged to be in E. subsect. Carinata in Pinheiro and Barros 2007.
