"Epidendrum kolanowskae belongs to the GROUP Pseudepidendrum , which is characterized by caespitose plants, canelike stems, acute to acuminate leaves, apical inflorescence without spathaceous bract, the petals filiform and the lip usually 3-lobed, with 3 parallel fleshy ribs, the apical lobe often bifurcate, and the pollinia “bird-wing-type”, and SUBGROUP Paniculatum, which has bicolor flowers (generally green with the lip and apex of the column white), the disc sometimes marked with purple to red. The species is recognized by the intermediate sized plants, the racemose or paniculate inflorescence, leaves orbicular to elliptic, disc of the lip with 3 ribs, surrounded by pale purple spots spilling onto the lobes. Epidendrum weerakitianum Hágsater, O.Pérez & E.Santiago always has elliptic leaves; sepals 3-veined, the lip with 5 ribs on the disc which is clearly marked with purple turning reddish-purple with age. Epidendrum paniculorotundifolium has orbicular-elliptic leaves, sepals 5-veined, and the disc of the lip also has 3 ribs, but the lip is immaculate. It is similar to Epidendrum paniculatum Ruiz & Pav. which has elliptic leaves, the lip marked with reddish-purple, the lateral lobes of the lip sub-orbicular and the mid-lobe bilobed, formed by a pair of strongly divaricate, falcate lobes; it is endemic to northwestern Peru."
