discovered or described since 1874. 5 



miles lanceolate, 4 in. long, in. broad, with many ovate and 

 ovate-lanceolate paleae on the ribs beneath : tertiary segments 

 oblong. Veins 8-io-jugate, deeply forked. Indusium very 

 fragile, Peru, Pavon. Described from a type specimen lent by 

 Mr. H. C. Levinge, in 1885. 



12. C. mexicana, Schlecht. So far as I can judge from sterile 

 fronds, the plants which have been widely spread in gardens 

 under the names of Ahophila Malzinei and A. Vangeertii are 

 forms of this species.
