 bran acea, inasqualiter obovata, valde obtusa, 7 mm. longa, cir- 

 citer 4 mm. lata, ad basim leviter cuneata. Labellum saccatum, 

 trilobatum, lobi laterales late falcati, vel semicrescentiformes, 2.5 

 mm. longi, 2 mm. lati, acuti (erecti?), membranacei; lobus rae-

The material on which the above species is based is not all 



that one might wish for the preparation of a detailed description, 



but is sufficiently characteristic to make the new species readily 



distinguishable from all other members of the section Orsidice 



known to be natives of the Philippines. The middle lobe of the 



labellum is difficult to make out in dried specimens. On the front 



wall of the sac there is a conspicuous mass of fine, delicate hairs 



along the perpendicular median line.
