EARLY

Common Name The Incurved Rachis Epidendrum [refers to the peculiar incurved segments of the rachis]

Flower Size .6" [1.5 cm]

Found in south central Ecuador on the Amazon slope of the Andes in primary forests at elevations of 1200 to 1350 meters as a to medium sized, cool growing terrestrial or epiphyte with an erect, branching, cane-like, terete stem and carrying all along the stem, coriaceous, elliptic, bilobed and mucronate, margin entire and revolute when dry leaf that blooms in the winter through early spring on a terminal, racemose, distichous, erect, terete, 1.1 to 1.65" [2.6 to 3.8 cm] long, markedly flexuous, 5 to 6 flowered inflorescence with each rachis segment incurved below the bract so as to appear that the bract is retrose and carrying pendent, successively opening, greenish yellow flowers with the lip always facing the rachis.

"Epidendrum campylorhachis belongs to the GROUP Aquaticum, which has branching stems, distichous inflorescences, small, fleshy flowers and pubescent nectaries. The new species has a three-lobed lip with the base cuneate, narrowly oblanceolate petals and an oblique, deeply triquetrous ovary, with the rachis segments prominently incurved below each bract. It closely resembles Epidendrum lindae which has larger, wider leaves, the rachis flexuous so that the bracts are somewhat retrose, linear petals and a terete ovary, the lip is slightly cuneate with the lateral lobes subquadrate. Epidendrum carnosiflorum C. Schweinf. has larger flowers, the dorsal sepals .4 to .44" {10 to 11 mm] long, and a three-lobed lip, the midlobe much larger than the lateral lobes. Epidendrum ruguosum Schltr. has larger, linear-oblong leaves and larger flowers, with the lip suborbicular and sepals .44" [11 mm] long. Epidendrum stenocalymmum Hágsater & G. Calatayud has small, ovate, leaves, a simple, erect raceme, entire, oblanceolate, unguiculate petals and the cuneate lip forming a deep sac in front of the column, so that the column is not visible."
