"Epidendrum huamantupanorum belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, usually apical inflorescence, the mostly filiform petals and the lip usually 3-lobed with 3 parallel fleshy keels, the apical lobe often bifurcate, the “bird-wing” type pollinia, at least the inner pair, and the SUBGROUP Pluriracemosumwhich has a racemose and few flowered inflorescence on an elongate peduncle, usually producing new racemes over the years and thus pluri-racemose, the rachis is elongate, and thus lax flowered, the flowers bicolored, basically green to brown with the lip white to purple, spotted or not. The species is recognized by the intermediate size of the plants, about 20" [50 cm] tall, narrowly elliptic and short acuminate leaves, racemose inflorescence, the greenish copper sepals .6" [15 mm] long and petals, column base greenish, apical half lavender, the lip hyaline white, the calli and ribs lavender, surrounded by a darker ring, the convex lip with the lateral lobes hemi-elliptic. Epidendrum rodrigoi Hágsater endemic to Colombia, has elliptic-lanceolate leaves, 7 simultaneous, green flowers, the clearly 3-lobed lip pink, the lateral lobes dolabriform. Epidendrum oenochrochilum Hágsater, Ric.Fernández & E.Santiago has elliptic, acute leaves 1.12 to 2.6" x .4 to 1" [2.8 to 6.5 x 1to 2.5 cm], purple-brown colored flowers with the lip yellow-brown or dirty pink, the lateral lobes of the lip subquadrate. Epidendrum paniculatum Ruiz & Pavón has a paniculate inflorescence with green flowers, the apex of the column and lip white, the disk with numerous dark red markings, sepals .48 to 52" [12 to 13 mm] long."
