Flower photo is not correct, I leave it so it can be IDed correctly, all references state the lip has no fringe hairs

Common Name The Jaji Epidendrum [A town in Merida state of Venezuela where the type was collected]

Flower Size 5/8" [1.75 cm]

Found in Venezuela, Colombia, Ecuador, Peru and Bolivia at elevations of 1300 to 2540 meters in wet montane forests on smooth trunked trees as a miniature to small sized, cool to cold growing epiphyte with short, gradually widening stems forming an erect, fusiform pseudobulb, enveloped basally by 2 to 3, scarious, loose, tubular, imbricating sheaths from which a single, apical, articulate, erect, coriaceous, upper side dark green, with the parellel veins clearly marked in white and reddish purple beneath, sessile, oblong-elliptical to elliptical, obtuse, margin entire, spreading, conduplicate into the apex of the stem leaf that blooms at most any time of the year on a short, peduncle .4" [1 cm] long, terete, straight, thick, unornamented, rachis .4" [1 cm] long, densely and simultaneously 3 to 8 flowered inflorescence arising on mature stems with triangukar, acuminate, embracing, shorter than the ovary floral bracts and carrying flowers clustered towards the apex and the lip always facing the axis of the inflorescence.

"Epidendrum jajense belongs to the GROUP Jajaense GROUP Jajense which is characterized by the caespitose plants with thickened stems, a single sessile leaf with the upper side dark green and the veins marked white, short racemose or sub-umbellate inflorescence with or without a spathe, with compact flowers, the lip always facing towards the axis of the raceme. Epidendrum jajense is recognized by the greenish yellow tinged pink to pink flowers, sepals .38 to .44" [9.5 to 11 mm] long, the margins revolute and thus semi-tubular, linear petals and the lip deeply 3-lobed, the lateral lobes obliquely ovate, narrow, with the apical corner acute, and the mid-lobe oblong, the apex obtuse. Epidendrum unifoliatum Schltr. is vegetatively similar, but the inflorescence has a tubular spathe covering nearly the whole peduncle, and the 3-lobed lip has wide lateral lobes, and the mid-lobe is sub-quadrate with the apex emarginate."
