Whole plant 1--Г7 dm. high. Stem swollen below and rising from the base of 
the previous year’s pseudo-bulb; lower portion enclosed within the leaf-sheaths. Leaves 
2 or 3, horizontal, unequal in size, the larger one about 6 cm. long and 4 em.

reflexed, longer than the ovary. Flowers sessile, very small, reddish purple. Dorsal

Although most nearly related to М. Wailichii, the very different leaves at once distinguish this 
plant from any of the numerous forms of that species. It has also inuch smaller flowers and a very 
differently shaped lip.
