Common Name Endres' Epidendrum [German Orchid Collector-Central America 1800's]
Flower Size 3/5" [1.5 cm]
Found in Costa Rica and Panama in windy, premontane and lower montane cloud forests at elevations of 1200 to 2400 meters as a small to medium sized, cool to cold growing epiphyte with clustered, terete, cylindric stems with black verrucose sheaths that reach about a foot [30 cm] and stiff, distichous, elliptic-lanceolate to ovate, obtuse or retuse leaves articulated to the basal leaf sheaths which blooms on a terminal, few flowered, racemose inflorescence subtended by elliptic-lanceolate, acute, foliaceous bracts and giving rise to relatively large for the size of the plant, flat, fragrant flowers occuring in the winter and spring.
" Epidendrum endresii belongs to the GROUP Oerstedella which is characterized by the sympodial habit, mostly verrucose stems, and the rostellum which is perpendicular to the axis of the column instead of parallel forming a wide, open sinus and without a viscidium, and the SUBGROUP Verrucosum recognized by the small to medium sized, membranaceous flowers with sepals and petals immaculate, a bilobed clínandrium hood slightly surpassing the body of the column, obovoid subequal pollinia with long granulose caudicles. The species is recognized by the ovate to narrowly ovate leaves .4 to 1.32" [1 to 3.3 cm] long, white flowers, with the bicallose lip nearly totally violet-blue, or white wlth a small violet-blue spot on the isthmus and the apex of the column 4-lobed and violet-blue; sepals .32 to .44" [8 to 11 mm] long. Epidendrum pumilum Rolfe has greenish yellow flowers, sepals .2 to .28" [5 to 7 mm] long, lip with a pair of purple spots, the apex of the column 3-lobed, white, the callus tridentate, and the apical margin of the lip dentate. Epidendrum parviexasperatum Hágsater has larger, elliptic-lanceolate leaves .6 to 2.28" [1.5 to 5.7 cm] long, apical and lateral inflorescences with brown bordered yellow tepals, the lip white marked with violet, the apex of the column 4-lobed. Epidendrum x monteverdense (Pupulin & Hágsater) Hagsater, the natural hybrid cross beetween E. endresii and E. exasperatum Rchb. f. has vigorous, branching stems, sepals and petals cream- colored, the lip with a couple of violet spots, and the apical lobes of the column sometimes apically marked with violet."
