Common Name or Meaning The Inhibited Flowering Epidendrum [refers to the proximity of the flowers to one another causing them not to open properly and that if a flower is removed it opens fully, therefore they are inhibited]

Flower Size .2" [5 mm]

Found in Costa Rica on the Oso Peninsula in disturbed, lowland forests at elevations around 200 meters or less as a medium sized, hot, pendent growing epiphyte with several, born from a short creeping rhizome, pendent, branching, cane-like, terete, flexuous, producing a few, long main stems, ca. 16" [ca. 40 cm] long, and several shorter secondary stems, branches, ca. 1.6 to 4" [4 to 10 cm] long, from the leaf axils of the main stems carrying 9 to 16 on the main stems, 3 to 5 on the secondary stems, dissimilar, slightly recurved, narrowly-ovate, obtuse, coriaceous leaves that blooms in the mid fall through mid winter on a terminal, on both the main stem and branches, racemose, distichous, congested, occuring only once, short peduncle that is completely enveloped by 2 imbricating bracts, simultaneously 2 to 3 flowered inflorescence with larger than the ovary, acute floral bracts and carrying diurnally, sweetly fragrant flowers that always have their lips facing the rachis.

"Epidendrum inhibitiosum belongs to the GROUP Ramosum which is characterized by the monopodial, much branched stems, apical inflorescence, and distichous flowers; and SUBGROUP Paranense which has pendent plants and large, spreading leaves, >.2" [> 5 mm] wide. The species is recognized by the terete, flexuous stems and reddish-green leaves, the flowers nearly closed, large, sepals .72 to .76" [18 to 19 mm] long, flowers pale brownish green, the lip with the callus white and mid-vein purple, column whitish, suffused with purple, margin of the lip entire. It is similar to Epidendrum singuliflorum Schltr. from southern Mexico and Guatemala which has smaller, concolor green to greenish brown flowers, spreading sepals .36 to .48" [9 to 12 mm] long, elliptic, obtuse petals. Epidendrum sculptum Rchb.f. which has green stems and flowers, the small flowers half open, sepals .36 to .6" [9 to 15 mm] long, flowers are concolor, green to yellowish green, and the lateral lobes of the lip have a generally erose margin. Epidendrum isomerum Schltr. has long stems, with long, narrow, acute to acuminate leaves 2 to 4.4" x .08 to .12" [5 to 11 x 0.2 to 0.3 cm], a single flowered inflorescence, the flower partly open, sepals .56 to .64" [14 to 16 mm] long, and the lip is entire, rhombic-triangular. Epidendrum zunigae Hágsater, Karremans & Bogarín, which grows close by to E. inhibitosum, has long, narrow, linear-lanceolate leaves 2 to 4" x .2 to .32" [5 to 10 x 0.5 to .8 cm], small flowers, sepals .4 to .44" [10 to 11 mm] long, the lip is cordiform, acute, bicallose, the calli thickened at the base and ending in low ribs, the clinandrium is funnel-shaped."
