Common Name Cesar's Epidendrum [Cesar Fernandez, Venezuelan Agronomical Engineer current]

Flower Size .6" [1.5 cm]

Found in Colombia and Venezuela on rocks in road cuts at elevations around 1700 to 3200 meters as a small to medium sized, cool to cold growing epiphyte with erect, cane-like, terete, thin, straight stems producing new stems from near the apical internodes of the previous stem and carrying 2 to 15, along along the stem, alternate, suberect, subcoriaceous, oblong-lanceolate, apically bilobed, low dorsal keel, margin entire leaves that blooms in the later spring through late fall on a terminal, erect, occuring only once, terete, thin, ebracteate, arching-nutant, 1/4" [6 to 8 mm] long, racemose, 4 to 19 flowered inflorescence with narrowly triangular, acuminate, about half as long as the ovary floral bracts and carrying simultaneously opening, resupinate flowers.

"Epidendrum caesaris belongs to the GROUP Diothonea SUBGROUP Diothonea characterized by the branching habit, linear- lanceolate to lanceolate, bilobed leaves, arching-nutant, racemose inflorescence, membranaceous or rarely fleshy flowers, entire to 3-lobed lip, with an erose margin, ecallose, with 1 to 10 thin, glabrous to erose keels, the column united to the lip from totally to obliquely to free, and the reniform anther. This species is recognized by the simultaneous, small, translucent, pale pink to reddish flowers with the base of the sepals and petals yellowish, the flowers on a short, compact inflorescence, an arching column, subacute tepals, and a subentire, straight, subcordiform lip with 3 to 5 keels on the disc of the lip. It is similar to Epidendrum restrepoanum which grows in the same general area and has scarlet red flowers with a yellow lip and column, externally warty, pustulate sepals, an arching, nearly completely free column, deeply cordate, three-lobed lip, shallowly emarginate and 5 to 7 keeled. Epidendrum oxysepalum Hágsater & E.Santiago has very similar purple-pink flowers, but with narrower, acute floral segments." Hagsater etal 2007
