This plant is an excellent match to the photo of M. meleagris in the POWO. Maxillaria sanguinolenta produces intermediate growths that flower from the leaf axils in flushes of small flowers, different from this plant, which is a match for M. meleagris in Eric Christenson's unfinished Monograph on Maxillaria. Supporting photos of Maxillaria meleagris can also be found in orchidroots.com and the OW. There is an excellent photo of M. meleagris in the IOSPE.
