Common Name The False Epidendrum schumanniana Epidendrum

Flower Size .6" [1.5 cm]

Found in central Panama, in warm humid jungle on very tall trees, at elevations of 450 to 1100 meters and is a medium to giant sized, warm to cool growing epiphyte with simple, cane-like, terete, erect stems enveloped basally by tubular, purple-gray warty, leafless sheaths and carrying in the apical half, alternate, articulate, narrowly oblong-elliptic to ovate, obtuse, subcoriaceous leaves that blooms in the fall through spring on apical to lateral, racemose or paniculate, 5 to 15 per branch, erect, laxly, simultaneously to 50 flowered inflorescence with much shorter than the ovary, lanceolate, acuminate, progressively shorter floral bracts and carrying showy, resupinate, fragrant flowers.

"Epidendrum pseudoschumannianum belongs to the GROUP Oerstedella which is characterized by the sympodial habit, mostly verrucose stems, and the rostellum which is perpendicular to the axis of the column instead of parallel, forming a wide open sinus, without a viscidium, and the SUBGROUP Wallisii which has large, fleshy flowers, the lip entire or 3-lobed, the midlobe of the lip bilobed, the clinandrium-hood petaloid, and the pollinia obovoid, laterally compressed, with granulose caudicles. The species is recognized by the very showy flowers, violet-blue dorsally, pale orange ventrally, with dense reddish brown spots, with the líp and the apex of the column violet. It is similar to E. schumannanum Schltr. which differs in the blue-violet to pink flowers with some violet to reddish brown dots, the pink-lilac lip with violet veins or dots; the lateral lobes of the lip are falcate to subrectangular and apparently endemic to Costa Rica. Epidendrum wallisii Rchb. has fewer, much larger flowers with sepals .6 to .92" [18 to 23 mm] long, sepal and petals yellow, sometlmes with reddish brown dots, and the lip white turning yellowish, with purple lines or dots and is known from Costa Rica to western Colombia."
