 late outline. Texture thick, subcoriaceous. Margin entire through- 

 out. Midrib comparatively stout. Secondaries slender, branching 

 from the midrib at an angle of 30° to 40°, slightly curved, distant, 

 parallel, often obsolete, camptodrome." Berry, op. cif. Tliis descrip-

 margin, opposite or subopposite. camptodrome, the lowermost pair is 

 thin and very close to the margin.
