Epidendrum sect. Polycladia Rchb.f. 1861[1] is a section of the Subgenus E. subg. Amphiglottium Lindl. 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.
Like the other members of E. subg. Amphiglottium, the members of Epidendrum sect. Polycladia "possess a long leafy stem with distichous leaves, an absence of any tendency to form pseudobulbs, a peduncle suddenly covered with close sheaths, and a lip wholly united to the column."[2]
Lindley anticipated the section Epidendrum sect. Polycladia by publishing E. porphyreum under the title "AMPHIGLOTTIUM; floribus paniculatis.[3]
Reichenbach placed 16 species in this Section. The following species are recognized by Kew (page numbers refer to Reichenbach 1861):
