Found in western Oaxaca state of Mexico on oaks in oak forests at elevations of 1200 to 2000 meters as a small to large sized, cool growing epiphyte with cane-like, terete, slightly laterally compressed in the apical third, erect stems enveloped completely by tubular, leafless and in the apical third, thin, papery leaf-bearing sheaths and carrying 2 to 12, erect, thin, narrowly elliptic-lanceolate, obtuse to rounded, basally clasping and articulate to the leaf-bearing sheaths that blooms in the fall through spring on a terminal, over various years, on a newly matured and older canes, dense, arching, terete, erect, 1" [2.5 cm] long, simultaneously 10 to 25 flowered inflorescence and carrying fleshy, resupinate, fragrant flowers.

"Epidendrum roseoscriptum is part of GROUP Pseudepidendrum SUBGROUP Paniculatum characterized by the caespitose habit with cane-like stems carrying acute to acuminate leaves usually booming on an apical inflorescence and carrying flowers with filiform petals, and a usually 3 lobed lip with 3 parallel fleshy keels, with the apical lobe often bifurcate and the "bird wing" type pollina. The species is closely related to E. veroscriptum Hágsater, but can be distinguished by the disc of the lip with a single, large pink blotch and the apical lobes usually obsolete, or barely separated from the basal lobes by shallow sinuses. E. veroscriptum usually has a ring of deep purple dots around the disk, and the apical lobes are clearly separated from the basal lobes by deep, narrow sinuses. E. isthmii Schltr., found at lower altitudes, has green and white flowers, a lip without any rose or purple markings, and apical lobes clearly separated from the basal ones, which are rectangular, with erose margins."
