* Flowers brown." 
This has the habit of O. pleistophylla, J. J. Sm., of Celebes, but differs from all of this 
eroup known to me in the extremely slender rhachis of the raceme, and in the shape of 
the lip. The flowers are very minute, and in the only raceme present are in bud, so 
that it is difficult to make out the structure.
