Flower Size 1" [2.5 cm]

A reed stem Epidendrum from Jamaica, Cuba, Dominican Republic, Haiti, Jamaica, Leewards, Puerto Rico, Windwards, French Guiana, Guyana and Venezuela in wet dense forests on thick trees or along rivers at elevations of 250 to 1600 meters that grows as a medium to large sized, well shaded, hot to cool growing epiphyte with a scandent stem giving rise to new stems from the middle of older ones and enveloped basally by sheaths and carrying many distichous, distal, rather thin, elliptic to oblong-elliptic, acute to subacuminate leaves that blooms on a terminal, arcuate to pendant, shorter, several flowered, racemose inflorescence that has successive opening, fragrant flowers.

"Epidendrum jamaicense belongs to the GROUP Arbusculum SUBGROUP Incomptum which is characterized by the successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, a short apical inflorescence with fleshy greenish to violet-green flowers with short ovaries, the lip entire to 3-lobed, and the Proligerum Complex, which has the ovary inflated, forming a vesicle behind the perianth. The species is recognized by the sub-coriaceous leaves, the successive flowers with a prominent ventral nectary which inflates the ovary over two-thirds its length, acute petals, reniform, bicallose lip, straight column, narrow, and the enormous stigmatic cavity which occupies the whole length of the column. Epidendrum ochrochlorum Barb.Rodr. is green and has larger flowers, sepals .56 to .6" [14 to 15 mm] long, acute, the lip is very similar in shape, the base cordate, with the mid-lobe of the lip emarginate and thus bilobed, but the sides of the lip are obliquely revolute, so that in natural position it looks triangular. Epidendrum proligerum Barb.Rodr. is also larger, with the sepals .48 to .52" [12 to 13 mm] long, has the mid-lobe of the lip entire, not emarginate, with the base of the lip cuneate. Epidendrum morganii Dodson has a widely cordiform, entire lip, sepals .52 to .72" [13 to 18 mm] long, and single veined petals. " Hagsater etal 2018
