Mt. Mou ; high forest in gnlly; serpentine ; 1500 ft. 4G4. 



Differs from typical C. albi/rous (as described by Founder and in Hooker 

 and Bakor''s 'Synopsis,' and as represented by specimens collected by 

 Pancher, and by Schlechter 14841) in the broader ultimate pinnules, whose 

 maro-in/arc entire and not crenate ; and in the fewer sori, the distal part of 



the pinnules being without them.

Ignambi; high forest ; gneiss; 4000 ft. 15G3. 



Approaches nearest to C. aneitense from the New Hebrides, but difTers in 

 the shorter pinnules, liroader ultimate segments, blunter apices, the sh:ipe 

 of the frond, the rreeto-patent pinnoo, the colour of the rhacliis, etc. It is 

 renuirkablo anunig tree-ferns for the relatively small, ungraceful, and coarse- 

 textured fronds, which make it a singular associate of the arborescent filmy 

 LeptopU'ris WUkcs'iana, with which it gro^vs in abundance in the sunnuit 

 cloud-forest of Ignambi.
