Common Name The Distal Margin of the Lateral Lobes E paniculatum Epidendrum [refers to the shape of the lip apex]

Flower Size .8” [2 cm]

Found in central Peru through western Bolivia in thickets and forests at elevations of 600 to 2400 meters as a large sized, warm to cold growing epiphtye with simple, cane-like, laterally compressed, erect, straight stems carrying numerous, all along the stem, alternate, articulate, erect spreading, elliptic, shortly acuminate, margin entire leaves that blooms in the fall on a terminal, occuring only once, without a spathe, peduncle 3.4” [8.5 cm] long, laterally compressed, flattened, erect, straight, nearly completely enveloped by 4 tubular, triangular-lanceolate, acuminate, partly imbricating bracts, rachis 1.28” to 2.12” [3.2 to 5.3 cm] long, 4 branched, somewhat spreading, each branch subtended by a basal, narrowly triangular, acuminate, amplexicaul bract, simultaneously about 50 flowered inflorescence with much shorter than the ovary, linear-triangular, acuminate, amplexicaul floral bracts and carrying resupinate, sweetly fragrant, pale green flowers.

"Epidendrum paniculolateribilobum belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, canelike stems, acute to acuminate leaves, usually apical inflorescence, the mostly filiform petals and the lip usually 3-lobed with 3 parallel fleshy keels, the apical lobe often bifurcate, the “bird-wing” type pollinia, at least the inner pair, and SUBGROUP Paniculatum , which has filiform petals, all pollinia “bird-wing” type, green and white flowers, often marked with purple on the disc of the lip and apex of the column. The species is recognized by the green and white flowers, sometimes the disc sparsely dotted with purple, the slightly reflexed sepals, the distal edge of the lateral lobes of the lip bilobed, and the mid-lobe deeply emarginated, forming two long, slightly divaricate, linear-oblong, rounded lobes. Epidendrum paniculatum Ruiz & Pavón has smaller plants, the disc of the lip strongly marked with red, the sepals spreading, the lateral lobes of the lip entire, and the mid-lobe forming a pair of strongly arched lobes. Epidendrum floribundum Kunth has immaculate green and white flowers, the lip with entire lateral lobes, and the mid-lobe forming a pair of strongly divaricate lobes which form a 90° angle between them. Epidendrum paniculourubambense Hágsater & E.Santiago has larger flowers, sepals .56 to 58" [14 to 16 mm] long, a white, immaculate lip with the margin of the semi-circular lateral lobes entire, not bilobed, and the ovary scarcely pubescent."
