obtuse, several-nerved. Lip simple, oblong-obovate, 
several-nerved, about 3.5—-4 cm. long and 2 cm. broad 
above the middle, with a long slender spur; dise with 
two short inconspicuous longitudinal calli; spur slender, 
acute at the tip, directed straight backward from the lip 
and only slightly curved, about 2.5 em. long and 4-6 
mm. broad at the throat. Column slightly winged and 
with two short broadly lanceolate arms at the apex. 
Among the Philippine species of Phaius, P. fragilis is 
most nearly allied to P.fnearifolius Ames and P. Lyonit 
Ames. The alliance to these species, however, is not 
very close. Phaius fragilis may easily be distinguished 
from these species by its lower habit of growth, by its 
shorter and broader leaves and especially by the long 
slender acute spur.
