ORCHIDACE.E 



nate. Foot stout, straight, with a very minute slender tubercle 

 at the base. Anther ellipsoid broadened into two divergent semi- 

 orbicular membranaceous wings. 



This little plant has numerous more or less close allies. It dif- 

 fers from BuWophyllum chryseum Ames in its smaller vegeta- 

 tive proportions, broad lateral sepals and hp and much smaller 

 dorsal sepal and petals. It is distinguished from B. halconense 

 Ames by shorter broader lateral sepals, notably smaller dor- 

 sal sepal and larger Up. B. latisepalum has much larger flowers 

 than B. sensile Ames, differently shaped sepals and a simple lip. 

 B. montense Ridl. has narrower leaves, taller scapes and flowers 

 which are nearly twice as large as those of B. latisepalum.
