"Epidendrum ramiro-medinae belongs to the GROUP Nocturnumwhich is characterized by the sympodial, caespitose plants, cane-like, non-fusiform stems, successive flowers on a short, racemose or pluri-racemose inflorescence, without spathaceous bracts, and large, star-shaped flowers, with similar sepals and petals; the flowers are mostly indistinguishable in shape. The species is recognized by the upper part of the stems strongly laterally compressed, ancipitose, 6 to 7 leaves distributed along the upper 3/4 of the stem, narrow leaves, .6 to 1.12" [1.5 to 2.8 cm] wide, ovary shorter 3 to 3.12" [75 to 78 mm] long than the sepals .36 to .4" [90 to 100 mm] long, lateral lobes of the lip narrowly semi-ovoid, rounded, mid-lobe 2.72 to 3" [68 75 mm] long, column .52" [13 mm] long. Similar to Epidendrum cocornocturnum Hágsater, endemic to central Colombia, has green plants, leaves 1.12 to 1.84" [2.8 to 4.6 cm} wide, a longer ovary .24 to .36" [60 to 90 mm], acuminate floral segments, lateral lobes of the lip triangular, acuminate, mid-lobe of the lip shorter, .2 to .24" [50 to 60 mm], and column twice as long, .76 to 1.04" [19-26 mm]. Epidendrum nocturnum Jacq., widely distributed throughout the neotropics has terete stems, relatively long, narrow leaves, a shorter ovary 1.8 to 2.48" [45 to 62 mm], smaller sepals and petals, 1.6 to 2.8" [40 to 70 mm] long, and linear petals. Epidendrum carpophorum Barb. Rodr. also has ancipitose stems, ranges along the Atlantic slope of Venezuela, the Guianas and southeastern Brazil, has 4 to 6, olive green leaves, the underside tinged purple, leaves 1 to 2.4" [2.5-6 cm] wide, a short ovary 3 to 3.12" [75 to 78 mm] and smaller flowers, sepals 1.2 to 2.4" [30 to 60 mm] long, the lateral lobes of the lip ovate-triangular, acute and short .6 to .8" [15 to 20 mm] long, and the mid-lobe very short 1.2 to 1.4" [30 to 35 mm]. Epidendrum angustilobum Fawc. & Rendle (syn. Epidendrum latifolium (Lindl.) Garay & Sweet is abundant in the Antilles and northern coast of Colombia, Venezuela and the Guianas, has dark green colored plants, wider leaves .08 to .28" [2 to 7 cm] wide and a much longer ovary 4.8 to 8" [12 to 20 cm]long, smaller flowers, sepals 1.68 to 2.6" [42 to 65 mm] long, the mid-lobe short, 1.44 to 1.8" [36 to 45 mm}. Epidendrum macroophorum Hágsater & Dodson, endemic to the western slope of the Andes from Panamá to northern Peru has dark green colored plants, longer, wider leaves, 3.8 to 8" x .92 to 2.8" [9.5 to 20 x 2.3 to 7 cm], a very long ovary 8.8 to 11.2" [22 to 28 cm), the mid-lobe of the lip short 1.4 to 1.87" [35 to 47 mm] and a very long column 1.2 to 1.36" [30-34 mm]."
