Found in Cundinamarca department of Colombia on the western slopes of the Cordillera Oriental in the transition zone between humid forests and the very wet, low, montane forests at elevations of 1700 to 2300 meters as a medium sized, cool to cold growing epiphyte with simple, cane-like, laterally compressed, ancipitous, erect, straight stems carrying 3 to 6, articulate, alternate, sub-coriaceous, unequal in length, basally smaller, linear-lanceolate, acute, erect, sub-parallel to the stem, margin entire leaves that blooms in the mid fall through spring on a terminal, racemose, arched, peduncle 2.4 to 4" [6 to 10 cm] long, laterally compressed, erect, striaght, almost completely enveloped by the 1 to 2, tubular, conduplicate, acute, papiraceous spathes, apically provided with a linear-oblong, acuminate, clasping bract, to 6.4" [16 cm] long, sub-densely, simultaneously about 45 flowered inflorescence with prominent, about as long as the ovary, linear-triangular, acuminate, clasping floral bracts and carrying resupinate flowers.

"Epidendrum tequendamae belongs to the GROUP Alpicolum SUBGROUP Alpicolum which is characterized by the simple, cane-like stems, 1 to 2 long, narrow, spathaceous bracts, fox-tail-like inflorescence and numerous flowers with a fleshy lip, triangular mid-lobe and roundish lateral lobes. The species is recognized by the long rounded wings of the column, which therefore puts the clinandrium-hood at the middle of the column when seen from above, the ochre colored flowers, with the column and anther pale greenish white. Epidendrum roezlii Hágsater has the clinandrium-hood at the apex of the column, the same level as the apex of the column wings. Epidendrum anthoceros Rchb.f. has oblong leaves, spreading sepals .4 to .44" [10 to 11 mm] long, lateral lobes of the lip erose-denticulate, mid-lobe linear-triangular, short acuminate. Epidendrum aenigmaticum Hágsater & Dodson has small flowers, ochre-orange colored inside, the lateral sepals .272 to .3" [6.8 to 7.5 mm] long, the transversely ovate-elliptic lateral lobes of the lip are upright, with the margin entire, and the mid-lobe is short and wide."
