 dried specimen. Perianth segments comiivent. Lateral sepals 

 about 4.5-5 mm. long, 2.5 mm. wide, triangular-lanceolate, fal- 

 cate, oblique, complicate-mucronate, three-nerved, forming a 

 deeply saccate mentum. Dorsal sepal about 4.5-5 mm. long, 1.6 

 mm. broad, oblong-lanceolate, complicate-mucronate, strongly 

 concave or cucullate, three-nerved. Petals much smaller, about 

 2 mm. long, .8 mm. wide, rutaeform or rhombic, obtuse or sub- 

 acute, one-nerved, pubescent on the upper half. Lip in natural 

 position sharply reflexed in the middle, the lower half broad 

 membranaceous with erect conduplicate sides, the upper half 

 narrowly oblong, obtuse fimbriate ; lamina when expanded del- 

 toid in outline, appearing trilobed, about 3 mm. long, 1.9 mm. 

 broad across the suborbicular hypochil, bicallose at the base, with 

 three approximate nerves. Column minute, provided with a pair 

 of subquadrate-triangular arms which terminate in subulate 

 teeth. Column foot unciform, below conspicuously fleshy-thick-

In vegetative character, this species closely resembles Bulbo- 

 phylhun lancifoUum Ames, but it has infinitely smaller flowers.
