Epidendrum flexuosum, a reed-stemmed Epidendrum common at mid-altitudes in Central America, is a species of orchid commonly called Epidendrum imatophyllum. It grows exposed to intense sunlight in the forest canopy, particularly on Guava species. E. flexuosum bears non-resupinate lavender flowers on a congested raceme at the end of a long peduncle.

Epidendrum subsect. UmbellataRchb.f. (1861) is a subsection of section E. sect. PlanifoliaRchb.f. (1861) of subgenus E. subg. EpidendrumLindl. (1841) of the genus Epidendrum of the Orchidaceae. Plants of E. subsect. Umbellata differ from the other subsections of E. sect. Planifolia by producing inflorescences which are umbel-like. In 1861, Reichenbach recognized ten species in this subsection. Of these, nine are recognized with the same names by Kew :
Epidendrum subsect. SpathaceaRchb.f. is a subsection of the section E. sect. PlanifoliaRchb.f. 1861 of the subgenus E. subg. EpidendrumLindl. 1841 of the genus EpidendrumLindl. of the Orchidaceae. Like the other subsections of E. sect. Planifolia, the species of E. subsect. Spathacea are characterized by a sympodial growth habit without pseudobulbs, a lack of any spathes or sheathes covering the base of the racemose inflorescence, and by flat leaves. The species categorized in Spathacea differ from the members of the other subsections by having large floral bracts, which make the inflorescence resemble a strobilus. Reichenbach originally placed eight species in this subsection :
The section Epidendrum sect. Planifolia of the subgenus E. subg. EpidendrumLindl. 1841 of the genus Epidendrum of the Orchidaceae was published in 1861 by Reichenbach It differs from the other three sections by having flat leaves. Like the other sections of E. subg. Epidendrum, the inflorescence grows from the apex of the stem, and bears no spathe or sheath at the base of the peduncle.
Epidendrum subsect. CarinataRchb.f. (1861) is a subsection of the section E. sect. SchistochilaRchb.f. (1861) of the subgenus E. subg. AmphiglottiumLindl. (1841) of the genus Epidendrum of the Orchidaceae. 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.
Epidendrum sect. SchistochilaRchb.f. (1861) is a section of the subgenus E. subg. AmphiglottiumLindl. (1841) of the Genus Epidendrum of the Orchidaceae. E. sect. Schistochila differs from the section E. sect. Holochila in that the species in E. sect. Holochila have undivided lips; the species in E. sect. Schistochila have lobate lips. The species in both E. sect. Schistochila and E. sect. Holochila have racemose inflorescences, unlike those in E. sect. Polycladia, which have truly paniculate inflorescences. Like the other sections of E. subg. Amphiglottium, the members of E. sect. Schistochila are sympodial orchids bearing thin stems with alternate leaves, a long peduncle covered with thin, imbricating sheathes, and a lip adnate to the very end of the column.
Epidendrum sect. PolycladiaRchb.f. 1861 is a section of the Subgenus E. subg. AmphiglottiumLindl. of the Genus Epidendrum of the Orchidaceae. This plants in this section differ from the plants in the other sections of E. subg. Amphiglottium by having truly paniculate inflorescences: the section E. sect. Holochila is characterized by racemose inflorescences and an undivided lip, and the section E. sect. Schistochila is characterized by racemose inflorescences and a lobed lip.
Epidendrum hemiscleria is a sympodial epiphytic orchid native to the tropical cloud forest of Ecuador and Peru, at altitudes near 3.3 km.
Epidendrum sect. Holochila Rchb.f. 1861 is a section of subgenus Epidendrum subg. Amphiglottium of the Orchidaceae. It differs from section E. sect. Polycladia by bearing inflorescences that are racemes, not panicles. It differs from section E. sect. Schistochila by having a lip with no lobes. Like the other sections of E. subg. Amphiglottium, plants of E. sect. Holochila exhibit slender stems covered with close imbricating sheaths which do not swell to form pseudobulbs, and terminal inflorescences covered at the base with close imbricating sheaths but without spathes.
Epidendrum smaragdinum is an epiphytic sympodial orchid native to the Neotropics. It has been found at 0.5 km above sea level in Napo, Ecuador It is also known from Brazil, French Guiana, Guyana, Peru, Suriname, and Venezuela.
Epidendrum calanthum is a terrestrial reed-stemmed Epidendrum orchid from the montane Tropical rainforest of Bolivia, Colombia, Ecuador, Peru, Venezuela, and the West Indies.
Epidendrum mancum is an epiphytic orchid that grows in the tropical low elfin cloud forests of Ecuador and Amazonas, Peru, at altitudes of 2–3 km.
Epidendrum parvilabre is a sympodial terrestrial orchid native to the mountainous (~2 km) tropical rainforests of Ecuador and Piura, Peru.
Epidendrum subgenus Aulizeum was raised from sectional status by Lindley in 1853. According to the Latin diagnosis, this taxon included those species of Epidendrum with a multi-lobate lip adnate to the column, with pseudobulbous stems, with the flowers sessile or born on racemes or panicles. In his further English description, Lindley stated that the species in this taxon have a horn-like stem which is only leafy at the end, and racemose inflorescences. In 1861, Reichenbach listed 32 species in this subgenus; of these, Kew recognizes 31 as separate species.
Epidendrum catillus is an epiphytic orchid native to Colombia, Ecuador and Peru at altitudes ranging from 0.8 km to 1.6 km.
Epidendrum cochlidium is a neotropical orchid which can grow both terrestrially and epiphytically in Peru and Venezuela at altitudes ranging from 1.2 km to 2.9 km.
Epidendrum stenophyton is a reed-stemmed Epidendrum orchid from the high-altitude tropics of Ecuador and Peru.
