tude about 20 m. Sibutu (Sulu Archipelago) , .Merrill 5296, October 13, 1906, 
in dry thickets near the seashore. 
This species is clearly distinguished from all others from the Philippines, 
except M. Ramosii, of which I have any knowledge, through its rhombic-lanceolate 
petals. At the base of the column on its outer surface there is a conspicuous 
deeurved tooth or papilla. The labellum is rotundate, deeply cordate-cleft at 
the base, and near the tip bears a curious callus which in dried specimens is 
blackish and which at its posterior end terminates in a minute fovea.

The flowers of this species are similar to those of M. balabacensis and M. 
Ramosii. In aspect, however, the plant is quite distinctive. The elongated 
peduncles, which are wand-like and conspicuously tall, are characteristic. Three- 
fourths of the peduncle, at least, is floriferous. The specimens examined bear 
two large leaves, the upper one lanceolate, the lower one ovate, and near the 
base a foliaceous bract. The flowers are caducous, consequently the peduncles, 
in mature specimens, seem to have the flowers crowded in short racemes.
