Common Name The Ila Epidendrum [Mountains in Ecuador]

Flower Size 1 1/4" [3.5 cm]

Found in Ecuador in very wet, tropical forests in central and western Ecuador at elevations of 250 to 700 meters as a medium sized, hot to warm growing terrestrial or epiphyte with simple, cane-like, laterally compressed, suberect, tall, slender stems enveloped by tubular sheaths and forming keikis in the apical half carrying several pairs [13 to 18] of distichous, all along the stem, alternate, articulate, narrrowly elliptic, acute, minutely apiculate, basally clasping, margin entire leaves that blooms throughout the year on a terminal, pendant, 12" [30 cm] long, few flowered racemose inflorescence with much shorter than the ovary, triangular, acuminate, amplexicaul floral bracts and carrying 3 to 7, simultaneously opening flowers produced successively over the years.

The fact that this species has clusters of white, softly fragrant flowers, with a long fringe on the lip, along the stem arising from previous years inflorescence as well as at the apex distinguishes it from others. Leave old spikes until dead and brown as they can rebloom for several years from a node above the old rachis.

"Epidendrum ilense belongs to the GROUP Jatunsachuanum , which is recognized by the caespitose habit, numerous narrow leaves, apical inflorescence from young stems, with lateral inflorescences in mature plants of some species, the inflorescences producing new racemes through time, the lip with fimbriate margins, the pollinia obovoid, not “bird-wing” type. The species is recognized by the subcapitate, few-flowered inflorescences, the flowers simultaneous, greenish white, the sepals dorsally tinged purple, lip entire, immaculate, with a pair of small calli, margin deeply fimbriate. Epidendrum jatunsachanum Dodson & Hágsater has a racemose, apical inflorescence with successive flowers, the lip 3-obed with purple spots on the disc of the lip, and a pair of sub-globose, prominent calli. Epidendrum hajekii R.Vásquez & Dodson has racemose inflorescences, the sepals linear-oblanceolate, lip 3-lobed, immaculate, with a pair of evident calli." Hagsater etal 2013
