Common Name or Meaning The Curved Sepal Epidendrum

Flower Size .6" [1.5 cm]

Found in Panama in cloud forests at elevations around 1400 meters as a miniature to small sized, cool growing epiphyte with branching, flexuous, main stem short, producing new branches from the lower and middle internodes which in turn produce flowering branches from the upper internodes and may produce new very short branchlets from subapical internodes carrying per stem or branch 3 to 8, distributed all along, narrowly lanceolate, unequally bilobed leaves that blooms in the later summer on a terminal, from the secondary branches, racemose, occuring only once, but each branch can produce new flowering branchlets, erect, zig-zag .6 to 1" [1.5 to 2.5 cm] long, successively [2] 4 to 5 flowered inflorescence without a spathe but has ovate, acute, shorter than the ovary floral bracts.

"Epidendrum curvisepalum is part of the GROUP Ramosum characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the SUBGROUP Rugosum which has a branching habit with few-flowered inflorescence from short, secondary stems, the leaf-sheaths rugose. The species is closely related to E. rugosum Ames, but is immediately distinguished by the falcate lateral sepals, which strongly diverge about the middle,the divergence being evident even in herbarium material, the ovate-triangular lip with margins strongly involute, and the 5-veined petals. E. rugosum, on the other hand, has straight lateral sepals, sharply triangular lip with only the basal margin slightly involute, and 3-veined sepals." Epidendrum suturatum is closely related to E. curvisepalum Hágsater & Dressler, but is immediately distinguished by the connate lateral sepals, which are adnate to the portion of the lip united to the column and clearly divergent even in dried material, the triangular lip with basal angles rounded, the linear-lanceolate, 3-veined petals, and the longer column terminating in a broad, rounded process on each side of the apex."
