Epidendrum subsect. Carinata is a subsection of the section E. sect. Schistochila of the subgenus E. subg. Amphiglottium 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.

E. attenuatum Lindl. (1853) (p. 389)

E. calanthum Rchb.f. & Warsz. (1854) as E. calanthum (p. 390) and E. paytense (p. 391)

E. cinnabarinum Salzmann ex Lindl. (1831) (p. 389)

E. imatophyllum Lindl. (1831) (p. 391) As of August 1, 2009, the World Checklist had no entry for this binomial, but accepted E. flexuosum G.Mey. (1818), which Reichenbach 1861 lists as a possible synonym. Kew listed E. imantophyllum with the same reference to Lindley, 1831. Lindley 1831 spells it E. imatophyllum.

E. fulgens Brogn. (1834) as a synonym of E. schomburgkii var. conflens (p. 389-390)

E. ibaguense Kunth (1816) as E. decipiens Lindl. (1853) (p. 391) and E. schomburgkii var. conflens (p. 389-390)

E. macrocarpum A.Rich. (1792) as E. schomburgkii Lindl. (1838) (pp. 389-390)

E. radicans Pav. ex Lindl.(1831) (p. 390)

E. spicatum Hook.f. (1851) (p. 389)

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