"Epidendrum timbiquiense belongs to the GROUP Albertii which is characterized by the sympodial habit, laterally compressed to ancipitose or somewhat fusiform-thickened stems, the apical or apical and lateral racemose, distichous inflorescence more or less with imbricating bracts on the peduncle, producing one flower at a time, and the SUBGROUP Allenii which is characterized by the stems with numerous leaves, the apical, rarely lateral inflorescence, peduncle elongate, bare, non-bract bearing, two-winged, the rachis short, covered by rounded, usually imbricating, bracts. The species is recognized, by the white flowers, sepals .52" [13 mm] long, very small, mostly not imbricating floral bracts .08 to .16" [2 to 4 mm] long, the rounded lip, cordate at the base, and the entire, reduced, clinandrium-hood. Epidendrum grayumii Hágsater & E. Santiago has greenish white flowers somewhat tinged with purple, .4 to .52" [10 to 13 mm] long floral bracts, the lip elliptic, with the base cuneate and the clinandrium-hood prominent. Epidendrum allenii L.O. Wms. has prominent floral bracts .24 to .4" [6 to 10 mm] long, the margin of the sepals revolute, and the lip obscurely 3-lobed, with a prominent clinandrium hood. Epidendrum nora-mesae Hágsater & O. Pérez has greenish brown flowers, (most often they are yellow whereas in the canopy in bright sunlight they become white, sepals .52 to .84" [14 to 21 mm] long, and the lip 3-lobed, and 8 pollinia."
