Common Name The Congestum-Like Epidendrum

Flower Size 1.2" [3 cm]

Found in Guatemala, Honduras, Nicaragua and Costa Rica in mangroves and rainforests at elevations of sea-level to 1000[1800] meters as a mini-miniature sized, hot to warm, pendant growing epiphyte with a simple, cane-like, laterally compressed, erect stems enveloped completely by leaf bearing sheaths and carrying 7 to 11, all along the stem, spreading, distichous, unequal, non-articulate, succulent, basally imbricating, glaucous, green, oblong to ovate-oblong, amplexicaul and conduplicate basally, obtuse, unequally bilobed, strongly revolute margins, with a dorsal keel, minutely dentate-fimbriate apically leaves that blooms in the winter and again in the late spring on a terminal, sessile, occuring only once, usually 2 flowered inflorescence with slightly shorter than the ovary, obovate, rounded, conduplicate, imbricating, unequal, apical margin dentate floral bracts and carrying simultaneously opening, non-resupinate, fleshy flowers.

This species along with E congestum, E uleinanodes are similar to E schlechterianum and many references put them all as synonyms of E schlechterianum but I follow Hagsater and leave them all separate.

"Epidendrum congestoides belongs to the GROUP Nanodes, characterized by the caespitose to creeping, sympodial plants, the short stems completely covered by the base of the non-articulate, fleshy, imbricating leaves, and the sessile, few-flowered inflorescence. The species is recognized by the two-flowered inflorescence, greenish bronze or reddish-purple tinted flowers, sepals ovate to ovate-lanceolate, .32 to .52" [8 to 13 mm] long, the lip reniform-semi-orbicular, somewhat embracing the short column .18 to .264" [4.5 to 6.6 mm] lon) in natural position, and the anther is short. Epidendrum congestum Rolfe has 2 to 3, smaller flowers with sepals .28 to .4" [7 to 10 mm] long and the lip cordiform, with the apex acute, anther obovate and apically truncate. E schlechterianum which has relatively long, greenish purple to olive green flowers tinged with red, the oblong-lanceolate sepals are .68 to .8" [17 to 20 mm long, and the lip cordate-reniform, minutely apiculate, the column .4 to .56" [10 to 14 mm] long with the anther elongate, subacute and apically dentate. E uleinanodes from Manaus to the foothills of the Andes in Ecuador and Peru has 4 flowers, a fimbriate clinandrium-hood and prominent, upturned, rounded lobes at the apex of the column."
