"E haenkianum from Machu Picchu belongs to the GROUP Arbuscula SUBGROUP Amplexicaule characterized by the successive growths, where the new growth is produced from a subapical internode of the previous growth, the acute to acuminate leaves and the paniculate inflorescence. The species has successive growths, where the new growth is produced from a subapical internode of the previous growth, the acute to acuminate leaves and the paniculate inflorescence. Epidendrum wigginsii has pendent, 16 flowered inflorescence and the membranaceous yellow-green flowers with a three-lobed lip, the transversely elliptic lateral lobes and the obcuneate, mucronate midlobe distinguish this species. E haenkianum closely resembles Epidendrum wigginsii from Ecuador which has a differently proportioned lip, the sepals about twice as wide and the calli much larger. Epidendrum alexii Hágsater & Dodson has small lateral lobes obliquely dolabriform-triangular, and an elongate midlobe dilated near the apex into a pair of semicircular lobes. Epidendrum amplexicaule Lindl. is vegetatively similar, but the lobes of the lip are oblong, truncate with the distal margin dentate." Adapted from Icones Plate 499 Hagsater 2001
