"Odontoglossum auroincarum is similar to O. epidendroides Kunth, but differs from it by having flowers with a shorter (ca. .4 to .44" [10 to 11 mm] long versus .52 to .56" [13 to 14 mm], and differently curved column with shorter wings. It differs from O. cruentum Rchb.f. and O. juninense Schltr. , by a different lateral curvature profile of the column, with broader and more rectangular column wings as well as a less lobulate anther-cap."
