Common Name Barbey-Boissier's Epidendrum [Swiss Orchid Collector late 1800's]
Flower Size 2" [5 cm]
Found in Nicaragua, Costa Rica, Panama and Venezuela in seasonally dry forests as a small sized, warm to cool growing epiphyte at elevations around 500 to 1850 meters with a short stem carrying several [6 to 7], alternate, conduplicate below and basally clasping, oblong-elliptic, apically unequally bilobed leaves that blooms in the spring on a short, single flowered, terminal inflorescence arising on a mature growth and carrying 5 to 10, simultaneous, nocturnally fragrant flowers held in an apical umbel.
Very similar to E difforme but differs in a smaller plant with large yellow green flowers and a lip that is twice as wide as E difforme and has lateral lobes that are much longer apically than the bilobed midlobe.
"Epidendrum barbeyanum is part of SECTION Difforme characterized by the caespitose, sympodial plants, fleshy, pale green to glaucous leaves, apical inflorescence, sessile, rarely with a short peduncle, one-flowered to many-flowered, and then corymbose, without spathaceous bracts, fleshy, green to yellowish-green rarely white flowers. The species can be recognized by its laterally compressed stems, big flowers, flabelliform, undulate lateral lobes of the lip, midlobe much smaller than the lateral lobes, separated from them by deep siniiˇ forming two, divergent, triangular to subrectangular, acute to rounded lobes, c1inandrium-hood reduced, entire. It differs from Epidendrum althausenii AD.Hawkes, an Amazonian species, which, has a subquadrate lip, semi-ovate lateral lobes, without deep sinii, an emarginate midlobe, and a prominent, dentate-fimbriate c1inandrium-hood. Epidendrum cremersii Hágsater &. L.Sánchez from French Guiana, has trapezodal, 3-lobed lip, with ovate lateral lobes, surpassing the very small midlobe, and a prominent, erose c1inandrium-hood. The species has been confused with Epidendrum latilabrum Lindl. from Brazil, but its lip is four times broader than long, and curved downwards on each side, with suborbicular to subrectangular, entire lateral robes, without a deep apical sinus, and an evident, elongate-fimbriate c1inandrium-hood. The new species Epidendrum vulgoamparoanum Hágsater & L.Sánchez has elliptic to ovate leaves, a widely obovate, obscurely 3-lobed lip, with many thickened veins; the midlobe obscurely bilobed, and a prominent, erose-fimbriate c1inandrium-hood."
