"Epidendrum angustilobum belongs to the GROUP Nocturnumwhich is characterized by the sympodial, caespitose plants, short, racemose or pluri-racemose infloresce nce, without 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, ancipitose stems, relatively wide leaves, to 2.8" [7 cm] wide,. 2 to 3 times longer than wide, long ovary 4.8 to 8" [120 to 200 mm], and the body of the capsule clearly above the middle of its length. Epidendrum nocturnum Jacq., is very widespread, has terete stems, relatively short and narrow leaves, with a short ovary, about as long as the sepals, 1.8 to 2.48" [45 to 62 mm] long, wilh the body of the capsule in the middle and occupying nearly lhe whole length. Epidendrum carpophorum Barb. Rodr. ranges along the Altantic in Venezuela, the Guyanas to southeastern Brazil, it also has relatively wide leaves, but the ovary is shorter, 2.4 to 4.8" [60 to 120 mm] long. Epidendrum macroophorum Hágsater from Panama to the Pacific slope of South America in Colombia, Ecuador and northern Peru, and has leaves 3 to 4 times longer than wide, with a very long ovary, 8.8 to 12" [220 to 300 mm] long. Epidendrum portoricense Hágsater & Ackerman is endemic to Cuba and Puerto Rico and has relalively narrow leaves, .8 to 1.6" [2 to 4 cm] wide, and a shorter ovary, 3.2 to 4.6" [80 to 115 mm] long, with the body of the capsule slightly above the middle.# Hagsater etal 2008
