Flower Size
Found in Risaralda, Boyaca, Huila and Cauca departments of Colombia on smooth bark in low forests and in montsne forest margins at elevations around 1600 to 2100 meters as a small to medium sized, cool growing terrestrial with elongate pseudobulbs carrying 2, membraneous, ovate, acute, subsessile base leaves that blooms at most any toime of the year on an erect, 5.2" [13 cm] long, termianted by a rachis .2" [.5 cm] long, subembellate, dense, many flowered inflorescence with subulate, much shorter than the ovary floral bracts and carrying small, brownish green to fresh green, tepals transluscent white to vey light yellow with a few purple striped flowers.
Similar to M histionantha but differs in the obliquely triangular-ovate, acute, obscurely 3 veined and almost free to the base lateral sepals and a reniform, much wider than long with undulate margined lip. M histionantha has obliquely oblong to elliptic-ovate, subobtuse and connate in the lower half sepals and the lip is almost orbicular to transversely elliptic, slightly wider than long with entire margins."
