"Similar red-flowered species to Epidendrum aromoense are: Epidendrum tulcanense Hágsater & Dodson has also red flowers but it is distinguished by the large white massive callus, formed by nine unequal tubercles: four basal ones and the main structure formed by five sub-equal tubercles. Epidendrum laurelense Hágsater & Dodson, that differ from E. aromoense by the carmine-red flowers on a much more open raceme, with a massive white callus formed by a semicircular sulcate, marginally plurilobulate fleshy plate, found between Tulcán and Maldonado, on the border between Ecuador and Colombia, on roadsides and rocks in wet forest between at around 2000 to 2500 m above sea level. Epidendrum coroicoënse Schltr. is another species similar to E. aromoense by the lacquer-red flowers; however, the former species is known from southern Peru and western Bolivia, along the upper Amazon slope of the Cordillera Oriental of the Andes, and differ from E. aromoense by the narrow leaves about 6–7 times longer than wide, the petals wider than the sepals, elliptic-sub-orbicular, the lip bearing lateral lobes overlapping with the mid-lobe when spread; and callus 5-tuberculate with two basal and three apical tubercles, and without keels. Epidendrum portokalium Hágsater & Dodson is another species with red flowers that resembles E. aromoense, but it is found on the Amazon slopes of the Andes in central Ecuador, and differs from E. aromoense by the callus unequally 7-tuberculed (with four basal tubercles and three apical ones" Epidendrum aromoense (Orchidaceae, Laeliinae), a New Species from the Coastal Dry Forests in Western Ecuador (PDF Download Available).
