"Epidendrum thompsonii belongs to the GROUP Andean SUBGROUP Vernixium which is recognized by its long erect, cane-like stems with subapical branching, the branches shorter, the rugose-warty leaf-sheaths, acute leaves. It is florally very similar to Epidendrum trachychlaena but the leaves of that species are much larger and fewer, being 3.2 to 6" x 1 to 1.98" [8 to 15 x 2.5 to 4.8 cm], and the margin of the lip obscurely serrulate. Epidendrum adamsii Hágsater & Dodson has longer and narrower sepals and petals, more rounded lobes of the lip, a straight column, the leaves bilobed, not acute" Hagsater etal 1999
