"Epidendrum physopus belongs to GROUP Andean SUBGROUP Soratae which is characterized by the branching habit starting on a primary stem, infundibuliform, rugose leaf sheaths, lanceolate, aristate, acute leaves, racemose sub-capitate inflorescence on a short, thin peduncle, and the bicallose lip. The species is recognized by the small sized plants, to 8" [20 cm] tall, linear to linear-lanceolate leaves .48 to 1.2" x .8 to .14" [1.2 to 3 x 0.2 to .35 cm, 2 to 5 green or yellow-green flowers tinged with reddish, sepals and petals .24 to .32" [6 to 8 mm] long, and the 3-lobed lip with lateral lobes obliquely semiovate obtuse and midlobe narrowly triangular. Epidendrum soratae Rchb.f. is vegetatively similar, but the leaves are lanceolate, .68 to 1.88" x .16 to .32" [1.7 to 4.7 x 0.4 to 0.8 cm], has 8 to 12 flowers per raceme, and the lip is slightly 3-lobed, with the midlobe very short. Epidendrum pachyphylloides Hágsater & E.Santiago has narrowly lanceolate leaves ca. .4" [1 cm] long, yellow flowers with .16 to .2" [4 to 5 mm] long sepals and petals, and a 3-lobed lip with the lateral lobes shorter than the midlobe. Epidendrum colliculosum Hágsater & E.Santiago has up to 10, white colored flowers diffused with purple, sepals .2 to .26" [5 to 6 mm] long, and a 3-lobed lip with dolabriform lateral lobes and a rectangular midlobe, the apex truncate."
