Common Name or Meaning The Ornate Epidendrum

Flower Size 1.2" [3 cm]

Found in western Panama in wet montane forests at elevations around 1800 to 2500 meters as a medium to giant sized, cool to cold growing epiphyte with branching near the apex with age, cane-like, terete, thin, erect to somewhat pendent stem carrying 7 to 12, throughout the apical half of the stem, alternate, articulate, subcoriaceous, lanceolate to narrowly ovate or oblong, acute apically leaves that blooms in the late summer and fall on a terminal, erect, terete, thin, 1.6 to 3" [4 to 7.5 cm] long including the .26 to 1.08" [.7 to 2.7 cm] long peduncle, racemose to paniculate, laxly to 22 flowered inflorescence with 2 to 7 simultaneous flowers and much shorter than the ovary, widely triangular, acuminate floral bracts.

"Epidendrum stolidium 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 Aberrans, which is characterized by the pink flowers, and the column with an elongate cylindrical clinandrium hood, the pollinia bird-wing type unequal and the caudicles lam inar. The species is recognized by the pink and white flowers, 3 prominent, green, three lobular appendages, alternate to the sepals which are dorsally ornamented with dentate keels; the elongate cylindrical clinandrium-hood is cream-colored and funnel-shaped at the end with a pair of comma-shaped magenta spots. The other species in the GROUP Oerstedella SUBGROUP Aberrans; E. centropetalum Rchb. f., E. pansamalae Schltr. and E. crescentilabllm Ames among them, do not have the alternate calyculum lobes behind the sepals which are dorsally glabrous. Epidendrum exasperatum Rchb. f. has smaller flowers with sepals .4 to .52" [10 to 13 mm] long, greenish brown with a white lip and the selpals are dorsally aculeate-verrucose; the short non-petaloid clinandrium-hood."
