LATE EARLY

Common Name Lucero's Epidendrum [location of the orchid]

Flower Size .64" [1.6 cm]

Found in Valle de Cauca department of Colombia in lower montane forest at elevations around 2200 meters as a giant sized, cold growing epiphyte with s cane-like, terete, branching, the branches produced from the apical internodes of the previous stem; primary stem 72 to 76" x .16 to .28" [180 to 190 x 0.4 to 0.7 cm], scandent, producing alternate branches sub-apically; secondary branches 3.04 to 10.4" x .12" [7.6 to 26 x 0.3 cm], these producing tertiary branches 2.2 to 5.4" x .16" [5.5-13.4 x 0.4 cm], and successively shorter branches, from which the flowers are produced; base of all branches covered by tubular, non-foliar, scarious sheaths and carrying 3 to 5 persistent at time of flowering, main stem not seen, distributed towards the apex of the stems, sub-coriaceous, dark green above, underside pale green, concolor, sub-spreading, slightly arched, with tubular, striated basal sheaths; blade oblong-lanceolate, sub-acute, margin sub-entire, minutely ciliate towards the apex, spreading leaves that blooms in the late summer and early fall on an apical, racemose, pendent, peduncle .4 to .52" [1.0 to 1.3 cm] long, terete, 1.8 to 2" [4.5 to 5.0 cm] long overall, laxly, simultaneously 2 to 4 flowered inflorescence with much shorter than the ovary, triangular-lanceolate, acute, embracing floral bracts and carrying resupinate, greenish yellow flowers without fragrance.

"Epidendrum luceroae belongs to the GROUP Polythallum, recognized by the monopodial, much branched stems, with a tall primary stem, numerous secondary and tertiary stems and the numerous shorter flowers stems, the nodding inflorescence bears only 3 to 4 pale yellow flowers, lip 3-lobed, bicallose, with 5 parallel ribs on the disc, which merge into a much-thickened mid-rib. The species is recognized by the plants to 88 to 96" [220 to 240 cm] tall, with sub-apical branching, leaves 1.4 to 2.68" x .28 to .52" [3.5 to 6.7 x 0.7 to 1.3 cm], oblong-elliptic, sub-spreading and somewhat arched, laxly few-flowered, producing 2 to 4 greenish yellow, concolor flowers, rachis straight; lip base cordate, lateral lobes dolabriform, petals with apical margin denticulate. It is vegetatively similar to Epidendrum polythallum, but that species has pale yellow flowers with the lip wine-red, base of the lip cuneate and lateral lobes obliquely triangular, margin of petals entire. Epidendrum amplexirisaraldense Hágsater & E.Santiago produces a new stem from an apical internode of the previous stem, leaves 1.5 TO 4.68" X .6 TO 1.28" [4 to 11.7 x 1.5 to 3.2 cm], elliptic, the inflorescence with the rachis flexuous and up to 30 green flowers, base of lip cuneate and the lateral lobes obliquely oblong."
