Although this plant does not match the photo in Kew's POWO, which shows flattened, ovate pseudobulbs, this plant does match the photo and description of M. pachyphylla in Eric Christenson's unpublished Monograph showing round, elongate pseudobulbs with solitary, rigid, fleshy leaves and large, sessile flowers. The lip is distinctive appearing wider and not pandurate, as seen in the similar species, M. parahybunensis. Supporting photos can be seen in the IOSPE and closely matching plant and flower images in the OW.
