margin, membranaceous, the nerve near the posterior 
margin somewhat prominent. Labellum 4 mm. long, with 
the terminal portion expanded into a transverse lamina 
which is 3-4 mm. wide; base of the labellum strongly ven- 
tricose-saccate, 2.5 mm. long, with a conspicuous hamate 
appendage within on either side of the prominent mid¬ 
nerve, constricted in front with each lateral margin con¬ 
vergent on the short isthmus which separates the sac from 
the terminal lamina; isthmus 1 mm. long; lamina narrowly 
subreniform, obscurely if at all apiculate in front. Column 
rather stout, with the rostellum deeply excised. 
In habit and flower structure A. zamboangensis suggests 
A. henguetensis Ames, but is much larger in all of its parts.
