Epidendrum subsect. Carinata
Introduction '''''Epidendrum'' subsect. ''Carinata''''' Rchb.f. (1861) is a 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 differs 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''  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.
Cytology The observed diploid chromosome numbers within ''Epidendrum'' subsect. ''Carinata'' are rather variable:*24 for ''E. flexuoxum'' and an individual of  ''E. fulgens'' described as ''E. mosenii''*28 for ''E. fulgens''*30 for ''E. calanthum''*40 for ''E. denticulatum'' and ''E. radicans''*52 for ''E. puniceoluteum''*60 for ''E. radicans''*70 for ''E. ibaguense'' and ''E. radicans''*~240 for ''E. cinnabarinum''
