"Epidendrum ivan-portillae belongs to the GROUP Porpax, which is characterized by the small, creeping plants with succulent leaves, single flowers from a small spathe, mostly green with a usually shiny wine-red lip. The species is recognized by the oblique, arched triangular column the oblong, 1-veined petals, and the lip which is oblong-obovate, apex truncate to shallowly emarginate, corners rounded, widest near the apex, and the flowers green, with the lip only wine-red at the base or throughout. Epidendrum maxthompsonianum Hágsater & Dalström also has oblique column, the oblong, relatively wide petals, forming a cucullate hood with the dorsal sepal over the column in natural position, but the flowers are smaller, sepals .26" [6.5 cm] long, the petals wider, 3-veined, and the lip is orbicular and totally wide-red. Epidendrum gnomus Schltr. has narrowly triangular, nearly linear petals, outstretched in natural position, and the lip is ovate, somewhat cordate at the base. Epidendrum viridibrunneum Rchb.f. has linear, free petals, with the lip elliptic, the base somewhat cuneate, and elongate calli. Epidendrum mathewsii Rchb.f., which also grows in the region, has larger plants but similar sized flowers (identical to those of E. porpax Rchb.f. from Central America), with the lip reniform, convex, 3-keeled, with entire margins, and the nectary is elongate and does not form a globose vesicle on the underside of the ovary."Hagaster etal 2018
