" Epidendrum eburneum belongs to the GROUP Nocturnum which is characterized by the sympodial, caespitose plants, short, racemose or pluri-racemose inflorescence, wilhout spathaceous bracts, usually large, star-shaped flowers, with similar sepals and petals, and the SUBGROUP Nocturnum which has cane-like stems, non-thickened towards the middle, and usually successive flowers; the flowers are mostly indistinguishable in shape, The species can be recognized by the laterally compressed stems, entire, suborbicular lip, rarely with a sinus on each side of the apicule, and then the apex 3-lobed, ovary .12 to .28" [30 to 70 mm] long; the body of the capsule occupying much of the ovary and slightly aboye the middle. It is similar to Epidendrum nocturnum Jacq., a wide-spread species, with terete stems, deeply 3-lobed lip, and the body of the capsule is .18 to .248" [45 to 62 mm] long, with the body of the capsule in the middle and occupying nearly the whole length. Epidendrum angustilobum Fawc. & Rendle (syn: Epidendrum latifolium (Lindl.) Garay & Sweet) which is widely distributed in the Antilles, Colombia, Venezuela and the Guyanas, and rare in Costa Rica and Panama has widely ancipitose stems, a deeply 3-lobed lip, and long ovary 4.8 to 8 [120 to 200 mm], wide leaves .8 to 2.8" [2 to 7 cm], and the body of the capsule short, aboye the middle of the ovary. Epidendrum mesocarpum Hágsater is found at higher altitudes of 900 to 2000 meters from the border of the states Oaxaca and Chiapas of Mexico, Guatemala, El Salvador, Honduras and Nicaragua, and has short, ancipitose stems, a deeply 3-lobed lip, and the ovary 4.8 to 6.4" [120 to 160 mm] long, with the body of the capsule elongate, slightly above the middle of the ovary. Epidendrum nocteburneum Hágsater & L.Sánchez the natural hybrid between E. nocturnum and E. eburneum is known from Nicaragua, Costa Rica and Panama, and has a clearly 3-lobed lip, and the body of the capsule occupies 1/4 of the ovary."
