Flower Size .8" [2 cm]
Found in the Leewards, the Windwards and Guyana at elevations of 100 to 900 meters as a medium to giant sized, hot to warm growing terrestrial or rarely an epiphyte with a thin, simple, cane-like stem carrying to 11, evenly distributed along the upper half of the stem, subcoriaceous, alternate, oblong-lanceolate, rounded apically, minutely bilobed, margin entire leaves that blooms in the winter, spring and summer on a terminal, racemose, erect, terete, thin, straight, 8" [20 cm] long, to 25 flowered inflorescence enveloped completely by imbricating, tubular bracts and shorter than the ovary, triangular, acute floral bracts and carrying successively opening, resupinate, non-fragrant flowers.
" Epidendrum revertianum belongs to the GROUP Secundum SUBGROUP Secundum which is characterized by the caespitose habit, erect, simple, cane-like stems, normally elongate peduncle of the inflorescence, erect raceme of resupinate, showy, colorful flowers, with the lip adorned by two calli and a median, narrow keel. The species is recognized by the terrestrial habit [reported as rarely epiphytic], suberect, compact leaves and the white flowers and the lip composed of four subequal lobes, the laterals more or less at a 45° angle. It closely resembles E. calanthum Rchb. f. & Warsc., a widespread species of continental South America with smaller flowers, usually purple tinged but often with pure-white albino forms. Epidendrum ibaguense Kunth is also caespitose, has yellow to reddish colored flowers and a straight column; it has been confused with the much more widespread E. radicans Pavo ex Lindl. which is similarly colored but has a repent habit, roots all along the stems and a curved column.
