"Epidendrum repaskyae belongs to the GROUP Saxicola characterized by the pseudobulbous stems, the caespitose or scandent habit, the prominent spathaceous bract apically rounded, the few-flowered erect inflorescence, the flowers purple or yellow, and the surface of the vegetative structures often rugose. The new species is recognized by the 3 to 4 creamy-white flowers with a yellow disc, sepals and petals cup-shaped, sepals .44" [11 mm] long, petals .4 x .2" [10 x 5.0 mm], the lip shallowly 3-lobed, the lateral lobes sub-quadrate-rounded, mid-lobe sub-quadrate, apex truncate with the middle margin revolute so as to appear emarginate. It is similar to Epidendrum wayqechaense, but that species is 2-flowered of similar color, sepals .52" [13 mm] long, petals .52 x .1" [13 x 2.5 mm], narrowly spatulate-oblanceolate, the lip clearly 3-lobed with the lateral lobes dolabriform and the mid-lobe revolute in natural position. Epidendrum herreranum C.Schweinf. has yellow flowers tinged orange to reddish bronze, sepals .72 to .94" x .28 to .4" [18.0 to 23.5 x 7.0 to 10 mm], petals .68 to .92" x .2 to .4" [17 to 23 x 5.0 to 10 mm], ovate-spatulate, lateral lobes of the lip semi-orbicular and the mid-lobe like an inverted “T”. Epidendrum tetartociclium Collantes & Hágsater also has 4 green flowers with the lip yellowish green, sepals 1 to 1.04" [25 to 26 mm] long, petals .96 x .32" [24 x 8 mm], oblong-elliptic to oblong-obtrullate. ."
