Found in Vera Cruz, Oaxaca and Chiapas states Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama and Venezuela in montane rainforests, elfin forests, pine-oak-liquidambar forests at elevations of 1300 to 2200 meters as a miniature to medium sized, cool to cold growing epiphyte with a subterete, branching, flexuous, slightly compressed stem enveloped by close fitting, somewhat compressed, leafless and tubular, slightly rugose, leaf-bearing sheaths and carrying thick, rigid, linear, oblong-lanceolate, retuse apically leaves that blooms in the fall and winter on a terminal, short, 2 to 2.4" [5 to 6 cm] long, few flowered inflorescence arising from the branches, enveloped completely by oblong-triangular, acute, conduplicate bracts, with somewhat inflated, longer than the ovary, imbricating, ovate-oblong, acute floral bracts and carrying 2 to 4 simultaneously opening, non-resupinate, apparantly odorless flowers.

Epidendrum pseudoramosum is closely related to several other species of the GROUP Ramosum SUBGROUP Ramosum. characterized by the monopodial, branching stems the spike-like, distichous inflorescence, and the single callus. The species is distinguished by the erect, branched plants, the stems slightly compressed, and the distichous, zigzag inflorescence with imbricated bracts. The floral segments are greenish white to yellowish, .2 to .24" [5 to 6 mm] in length, and the lip is triangular ovate, obtuse-rounded at the apex, and cordate at the base. It has been reported from the West Indies (e.g. Caray & Sweet. 1974) with basis in plants of the closely related Epidendrum antillanum Ackerman & Hágsater (= Epidendrum ramosum var. lanceolatum Criseb; see Hágsater & Ackerman ,1992). However, E. antillanum is distinguished by the shorter and wider leaves, fewer flowers, and its capsules are ovoid, elongate (the body .72 x .32 to .36" [18 x 8 to 9 mm], without a neck)."
