"Epidendrum beatricis-vasqueziae belongs to the DIFFORME GROUP which is characterized by the caespitose, sympodial plants, fleshy light green to glaucous leaves, the apical inflorescence without any spathe, sessile, rarely with a short peduncle, oneflowered to a glomerule, fleshy, and flowers green to yellowish-green, rarely white. The species is recognized by the somewhat compressed stems with 4 unequal leaves, the 2 to 5flowers , opening in succession but evetually all open at one time, large, the sepals 1.46" [36 mm] long, the petals 1.24" x .368" [31 x 9.2 mm], narrowly rhombic, base cuneate, the lip 3-lobed, strongly revolute in natural position with the lateral lobes obliquely revolute thus appearing triangular from in front, lateral lobes obliquely sub-orbicular, mid-lobe trapezoidal, the apex widely crescent shaped, and the column .36" [9 mm] long, short and thick. Epidendrum putumayoënse Hágsater & L. Sánchez has shorter stems, 1.6" [3.5 cm] long, sepals .98 to 1" [24.5 to 25.0 mm] long, narrowly oblanceolate, petals .92 to 194" x .1 to .12" [23.0 to 23.5 x 2.5 to 3.0 mm], narrowly oblanceolados, lip .48 x .96" [12 x 24 mm] obtrapezoid. Epidendrum platychilum Schltr. has similarly sized flowers, sepals 36 mm long, laterally compressed stems, 1 to 2 green flowers, and inflated, terete ovary, a cordiform lip with several prominent veins, and a column .36" [9 mm] long, thin. Epidendrum pseudokillipii Hágsater & L.Sánchez has taller plants, to 15.2" [38 cm] tall, 7 leaves, smaller flowers, sepals .68 to .72" [17 to 18 mm] long, petals .64 X .26" [16 x 6.5 mm], obovate-spatulate, the lip widely cordiform, obtuse, and the column short, .34 to .36" [8.5 to 9.0 cm] long."
