Common Name The Large Clinandrium Epidendrum [the place where the pollina are attached to the column]
Flower Size 1/3" [8 mm]
Chiapas Mx., 457m elev., 12 km beyond the village of Palenque,
Found in Mexico, Guatemala, Belize, Nicaragua, Costa Rica and Panama on the Atlantic slope, on lower trunks of large trees in humid forests at elevations of sealevel to 1000 meters as a miniature sized, hot to warm growing epiphyte with cylindric, compressed stems enveloped by leaf sheaths with fleshy, ovate to lanceolate, falcate, abaxially carinate, gray-green above, obtuse to acute, conduplicate below and subcordate at the base leaves that blooms at most anytime of the year on a terminal, erect, 2 to 3.2" [5 to 8 cm] long, single successively flowered, somewhat fractiflex inflorescence lasting several seasons with flowers that are weakly fragrant at sunup.
The long inflorescence, occuring more than once a season, successively single flowered, a prominent clinandrium that is larger than the body of the column, with a dentate frimbriate margin distinguishes this species.
" Epidendrum macroclinium belongs to the GROUP Physinga which is characterized by the generally small, caespitose plants, the inflorescence apical and racemose producing new racemes with time and thus pluriracemose, the successive flowers opening one at a time on an elongate peduncle with acuminate bracts, the lip entire and the ovary with a prominent vesicle. The species is recognized by the .6 to 1.8" [1.5 to 4.5 cm] long, spreading, ovate-lanceolate, gray-green leaves, sometimes with the foliar veins thickened and very evident on the basal half of the upper side of the leaves, the reflexed petals, obreniform lip with the narrow calli separated from the apex of the column and each other, and the very prominent, fimbriate-dentate clinandrium-hood. Epidendrum prostratum (Lindl.) Cogn. is vegetatively very similar, but the sepals and petals are partly spreading, the base of the lip deeply cordate, with 3 prominent keels on the disc, and the clinandrium-hood deeply emarginate, the margin entire. Epidendrum physodes Rchb.f. has the leaves inserted at a 45° angle to the stem, lanceolate, short-acuminate, gray-green leaves 1.4 to 2.8" [3.5 to 7 cm] long, spreading petals, the lip transversely elliptic with a pair of prominent, rounded calli in front of the column, and the clinandrium-hood short, fleshy, the margin slightly crenate."
