"Epidendrum viridibrunneum Rchb.f. belongs to the GROUP Porpax, which is characterized by the small, creeping plants with succulent leaves, single flowers from a small spathaceous bract, mostly green with a usually shiny wine-red lip. The species is recognized by the has linear, free petals, with the lip elliptic, the base somewhat cuneate, and the elongate calli. Epidendrum maxthompsonianum has an oblique column, the oblong, relatively wide petals, forming a cucullate hood with the dorsal sepals over the column, in natural position, the lip is orbicular. Epidendrum gnomus Schltr. has narrowly triangular, nearly linear petals, outstretched in natural position, and the lip is ovate, somewhat cordate at the base. Epidendrum mathewsii, which also grows in the region has larger plants but similar sized flowers, 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."
