TYPE LCDP /TYPE Photo © by A Diaz and The AMO Herbario Website Common Name The Parallel Petals Epidendrum
Flower Size 1.2" [3 cm]
Found in northern Peru on the summit of the Cordillera Occidental of the Andes just east of the Continental Divide at elevations around 2800 meters as a small sized, cold growing epiphyte with cane-like, pendent, more or less sinuous, laterally compressed, the new stem arising from a middle node of the previous stem
completely concealed by ancipitose, tubular sheaths, the lower ones non-foliar, red-brown, turning pale brown with age and carrying 6 to 15
per stem, fleshy, distributed along the apical 2/3 of the stems, distichous, articulate with the leaf sheaths; sheaths
tubular, ancipitose, minutely rugose, red-brown; blade spreading, twisted 90° so as to be on the same planes as the
stem, lanceolate, acute, coriaceous, deep green, margin entire, spreading leaves that blooms in the summer on a terminal, without a spathe, peduncle
.48 to .8" x .12" [1.2 to 2 x 0.3 cm], laterally compressed, ancipitose, curved, with a spathe-like bract near the apex, .32" [8 mm] long, conduplicate, acute,
somewhat incurved; rachis ca. .48" [12 mm] long 1.2" [3 cm] long overall, from the mature stem, flowering only once, racemose, the flowers in opposing pairs and at 90° between pairs simultaneously 2 to 5 flowered inflorescence with triangular, apex truncate, embracing, slightly shorter than the
ovary fkloral bractas and carrying approximately in opposing pairs, bright green flowers with the sepals somewhat dorsally
tinged brown, the anther brown, fragrance not registered.
"Epidendrum parallelopetalum is reminiscent of the GROUP Nanum
which has the leaves spreading and twisted 90° so as
to be on the same plane as the stem (as in Dichaea), lanceolate, acute; the flowers are produced in opposite pairs in species like
Epidendrum renzii Garay & Dunsterv. and have the nectary inflated ventrally behind the perianth. The flowers are reminiscent of
Epidendrum bonitense the 3-lobed lip with large calli, and narrow, oblong petals. The species differs from all these, however in the
sparsely leaved sinuous stems, and most notably by the laterally compressed peduncle of the inflorescence, with a relatively large,
spathe-like bract near the apex." Hagsater etal 2018
