The section ''Epidendrum'' sect. ''Planifolia'' of the subgenus ''E''. subg. ''Epidendrum'' Lindl. 1841 of the genus ''Epidendrum'' of the Orchidaceae was published in 1861 by Reichenbach〔"Folia plana" Reichenbach, H. G. "ORCHIDES" in Carl Müller, Ed. ''Walpers Annales Botanices Systematicae Tomus VI'' Berlin, 1861. p. 397.〕 It differs from the other three sections (''E''. sect. ''Equitantia'' Rchb.f. 1841, ''E''. sect. ''Sarcophylla'' Rchb.f., and ''E''. sect. ''Teretifolia'' Rchb.f.) by having flat (instead of round) 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. As defined by Reichenbach, the section contains four subsections: * ''E''. subsect. ''Spathacea'' (published as "''Planifolia spathacea''" with the diagnosis "Folia plana, bracteis spathaceis saepius ancipitibus"), with large floral bracts * ''E''. subsect. ''Umbellata'', (published as "''Planifolia umbellata''" with the diagnosis "Folia plana, bracteis depauperatis. floribus umbellatis"), with umbell-like inflorescences * ''E''. subsect. ''Racemosa'' (published as "''Planifolia racemosa''" with the diagnosis "Folia plana, bracteis depauperatis. floribus racemosis"), with racemose inflorescences * ''E''. subsect. ''Paniculata'' (published as "''Planifolia paniculata''" with the diagnosis "Folia plana, bracteis depauperatis. floribus paniculatis"), with paniculate inflorescences. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Epidendrum sect.
