"Epidendrum miniatum is part of the GROUP Pachychilum characterized by the monopodial plants with sub-apical branching, rugose leaf sheaths, by the relatively small leaves, parallel to the stem, the short, racemose, erect inflorescence, brightly colored flowers, yellow to orange to reddish pink, with an entire, conduplicate, lip embracing the column, without any pubescence in front of the stigmatic cavity nor on the lip, but generally with two small calli. The species is recognized by the smaller plants, up to 48" [120 cm] tall, leaves lanceolate, .6 to 2.4" x .2 to .36" [1.5 to 6 x 0.5 to 0.9 cm], parallel to the stem and partly imbricating; inflorescence dense, with 10 to 15, reddish-pink flowers, including the ovary, sepals .248 to .3" x .14 to .18" [6.2 to 7.5 x 3.5 to 4.5 mm]; apex of column blunt, without teeth. Epidendrum pachychilum Kraenzl. is vegetatively very similar, but the inflorescence few-flowered, with up to 8, sulfur-yellow to green flowers, sepals ca. .44" [11 mm] long, and the lip widely triangular when spread, column with an uncinate tooth each side at the apex. Epidendrum incapachychilum Hágsater & E.Santiago has taller plants, to 60" [1.5 meters] tall, leaves .96 to 2.2" [2.4 to 5.5 cm] long, inflorescence generally lax, with 7 to 9 [12] flowers colored reddish orange to yellowish orange with the ovary green, sepals .32 to .374" x .168 to .204" [8 to 9.4 x 4.2 to 5.1 mm], and the lip widely hemi-orbicular to widely triangular when spread, with a wide apicule, apex of the column with a pair of long straight teeth."
