Common Name Schumann's Epidendrum [German Cactus Specialist early 20th cen]

Flower Size to about 1" [to about 2.5 cm]

Found in Costa Rica and Panama? in lowland tropical rain forests at elevations of 250 to 1100 meters as a medium sized, hot to warm growing epiphytic herb with erect, cylyndric stems enveloped by verrucose leaf sheaths giving rise to coriaceous, elliptic-lanceolate, conduplicate at the base leaves that blooms in the winter and early spring on a terminal or lateral, simple to laxly branched panicle formed by 3 to 6, short, 4 to 7 flowered branches, rigidly erect, short to 4 to 8" [10 to 20 cm] long overall, simultaneously 22 to 32 flowered inflorescence with much shorter than the ovary, lanceolate, acute floral bracts and carrying resupinate, showy, fragrant, long-lived flowers.

"Epidendrum schumannianum 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, and without a viscidium, and the SUBGROUP Wallisii which has large, fleshy flowers, the lip entire to 3-lobed with the midlobe bilobed, clinandrium hood petaloid, the subequal pollinia obovoid laterally compressed, and long, granulose caudicles. The species is recognized by the attractive, bluish violet flowers with blue or reddish brown spots, the lip pink-lilac with violet veins or spots; the lateral lobes of the lip lanceolate-falcate or subrectangular, and restricted to Costa Rica. It is morphologlcally very similar to Epidendrum pseudoschumannianum Fowlie, which has the sepals dorsally blue-violet with the inner side pale orange with dense reddish brown spots, and the lip violet with the borders whitish and apparently endemic to the Pacific slope in central Panama, in the Valle de Antón."
