ORCHIDACE.^ 



a conspicuous thin ^"-shaped keel the arms of which — starting 

 on each side near the base — converge but diminish in height 

 toward the center, and on the under surface a low fleshy keel 

 that extends from the base of the lip to the junction of the arms 

 of the V-shaped keel. Column short, about 2.5 mm. long, three- 

 toothed at the apex, merging into a long foot which is about 

 5 mm. long, very slender, extending from the column at an ob- 

 tuse angle, and has a small fleshy dilation at its base with the 

 anterior portion conspicuously fleshy-thickened. 



In habit this plant resembles Bulbophyllum Elmeri Ames and 

 B. exile Ames, but has approximate pseudobulbs. It is very 

 similar in outward appearance to B. ovaUfolium Lindl., but it 

 has shorter sepals and much larger petals and lip. This species is 

 distinguished from B. stabile J. J. Sm. by larger leaves, shorter 

 dorsal sepal and petals. 



The approximate pseudobulbs, the small dorsal sepal and the 

 relatively large oblong Up with its V-shaped keel are character- 

 istic marks.
