rather large, I'/j — 2 m.M. broad, oflen very oblique and then nearly parallel 

 to the costae; valves of the indusium nearly equal, pale-brown, often pruinose. 



— A specimen received from Luzon (Leg. A. D. E. Elmer) has the costae 

 and costulae densely but deciduously furfuraceous, the tomentum adpressed, 

 pale-coloured, intermixed with some firm, spreading, pale, rather long, bristle- 

 like hairs. — Philippines. 



War. lainpongense, v. A. v. R., I.e.: Like var. Cumingii, but the 

 ultimate segments falcate, bluntly crenato-serrate. Costae and costulae copiously 

 (not densely), but deciduously furfuraceous, the tementum loose, pale-brown, 

 intermixed with long, firm, straight or crisped, bristle-like, dark-brown haii's

Lobes of pinnulae (leaflets) round, subhemispherical, very fornicate. Cap-
