EARLY

Common Name The Roughened Epidendrum [refers to the sheaths that cover the stem]

Flower Size .6" [1.6 cm]

Found in Ecuador and Peru on the eastern slope of the Andes at elevations of 2100 to 3300 meters as a medium to giant sized, cold growing terrestrial with cane-like, terete, erect, striaght stems carrying 31 on the primary and 8 to 12 on the branches, all along the stem, lower ones deciduous at flowering, ovate, acute, margin spreading, entire leaves that blooms in the winter spring and early summer on a terminal, without a spathe, paniculate, 2 to 5 branched, each 1.2 to 2.2" [3 to 5.5 cm] long, suberect to arching, peduncle, short, terete, thin, naked, rachis 1.6 to 2.92" [4 to 7.3 cm] long, terete, thin, straight, successively several to 40 flowered inflorescence with less than half as long as the ovary, linear-lanceolate, acuminate, apically gradually shorter floral bracts and carrying resupinate, yellow flowers.

"Epidendrum scabrum is a part of the GROUP Andean SUBGROUP Fritzianum characterized by the monopodial stems branched above, the ovate to ovate-elliptic, acute to short acuminate leaves, the lateral sepals obliquely united to the base of the column, and clearly three lobed lip. The species is recognized by the tall, monopodial, subapically scarcely branching, with ovate, acute leaves, the arching paniculate inflorescence with yellow, successive flowers, with several open at one time. By the habit it somewhat resembles E. fritzianum Hoehne which has a dense, racemose inflorescence, the leaves up to .14 x .72" [3.5 x 1.8 cm] the lip shallowly 3-lobed with the midlobe rounded and the disc thickened into a thick, rugose protuberance. Epidendrum putidocardiophyllum Hágsater & Dodson has a racemose inflorescence, large green flowers tinged purple, the sepals .68 to .72" [17 to 18 mm] long, the lateral lobes of the lip very small, obliquely triangular, and the long, rectangular midlobe with a pair of semiorbicular lobes at the apex. Epidendrum platyclinium Hágsater & Dodson has an elongate, racemose inflorescence, up to 10.8" [27 cm] long, the peduncle elongate; sepals .4 to .44" [10 to 11 mm] long, the clinandrium-hood funnel-shaped. Epidendrum molaui Hágsater & Dodson has the main stem branched throughout its length, a lax-flowered inflorescence on a short peduncle, dorsally papilose sepals and a deeply 3-lobed lip with a rectangular mldlobe. It somewhat resembles Epidendrum pittieri Ames which has .5" [12.5 mm] long petals, and a .4 to .44" [10 to 11 mm] long column." Hagsater etal 2006

" Epidendrum pittieri Ames, endemic to northern Colombia, also has yellow flowers but the inflorescence is always racemose, the sepals 12-14 mm long, and the ovary neither inflated nor ornamented. Epidendrum papillivesiculatum Hágsater & E.Santiago is vegetatively similar but the ovary is clearly inflated and papillose, the lateral lobes of the lip are hemi-orbicular with the margin denticulate, and the disc of the lip has a single mid-rib." Hagsater etal 2021
