The flowers are heavily suffused amd marked with purple and the sepals do not spread, giving the flowers a tubular appearance. The free portion of the lateral sepals are shorter and broader than those of M merinoi that are connate much farther beyond the sepaline tube. The lip od M chaucana is obovate with large, erect, rounded margins at the base while the lip of M merinoi is oblong with low basal margins." Luer 2005
