Common Name The Scandent Spathe Epidendrum

Flower Size 1.2" [3 cm]

Found in Ecuador on the eastern slope at elevations around 2600 to 2900 meters as a large to giant sized, cold growing epiphyte or lithophyte with a simple, cane-like, terete basally, laterally compressed above stems produced from the middle of the previous stem and carrying 6 to 7, along the apical half, erect, coriaceous, narrowly lanceolate, acute, smooth, margin entire, somewhat revolute leaves that blooms in the late fall and early winter on a terminal, arching, occuring only once, racemose, to 12 flowered inflorescence arising through 1 to 2, tubular below, conduplicate above spathaceous bracts with triangular, acute, much shorter than the ovary floral bracts and carrying simultaneously opening, resupinate, yellow to yellowish green flowers.

"Epidendrum ampelospathum would appear to belong to the GROUP Ampelospathum characterized by the scandent habit, with new stems produced from the middle of the previous stems, roots produced at the base of the main stem, and occasionally from the base of the successive stems, an apical, arching, racemose inflorescence subtended by 1 to 2, large, acute spathaceous bract, and flowers with a 3-lobed lip and 2 small, basal calli. The species at first sight is reminiscent of Epidendrum klotzscheanum Rchb. f. with which it shares the lanceolate leaves, arching, racemose inflorescence subtended by 1 to 2 large, acute spathaceous bracts, and the fleshy flowers with a 3-lobed lip. The new specles has a peculiar habit, with relatively short stems produced from middle of the previous stem, at around the first leaf, producing plants up to 100" [2.5 meters] tall, the stems with only 5 to 7 leaves, which are less than .8" [2 cm] wide, and the yellow to yellowish green flowers with very wide, trullate petals. Epidendrum klotzscheanum Rchb. f. has tall, simple stems, narrower floral segments, a rectangular midlobe of the lip and narrow, oblanceolate petals. Epidendrum prasinum Schltr. has a pendent, branching habit, with narrowly elliptic petals. Most other species with spathaceous bracts, and racemose, many flowered inflorescences and 3-lobed lips have caespitose plants, with the stems produced from the base of the previous stem. Only Epidendrum alpicoloscandens Hágsater & Dodson, produces the new stems about 1/5th from the base of the previous stem, and the plants are relatively short, with very narrow floral segments."
