"The flowers of E. santiagense looks like most members of the 2013 GROUP Pseudepidendrum SUBGROUP Paniculatum with green and white flowers and the lip marked with purple dots. The species has somewhat larger, unscented flowers, the sepals .6" [15 mm] long, 5 to 6 veined. Epidendrum christensonii Hágsater & E.Santiago has taller plants, ca. 40 to 48" [100 to 120 cm] high, and smaller flowers with sepals .304 to .32" [7.6 to 8 mm] long, the sepals green with the lip immaculate white. Epidendrum unguiculatum has sepals .72 to .8" [18 to 20 mm] long, the lip .348 to .4" x .44 to .6" [8.7 to 10 x 11 to 15 mm] and apparently does not have any spots on the lip except for the occasional purple calli, (the type from Iquitos, Peru, not the plants from Venezuela). Epidendrum paniculolateribilobum Hágsater, Ric.Fernández & E.Santiago, has much taller plants, to 100" [2.5 meters] tall, the flowers are greenish white, occasionally with the disc of the lip has a few purple dots, and the lateral lobes of the lip are bilobed. Epidendrum successivum Hágsater & F.E.L.Miranda has a racemose inflorescence with up to 22 successive flowers, the lip and apex of the column have a solid purple splotch." Hagsater & Dodson 2013
