discovered or described since 1874 . 185 
nules lanceolate, 4 in. long, J- in. broad, with many ovate and 
ovate-lanceolate paleae on the ribs beneath : tertiary segments 
oblong. Veins 8-10-jugate, deeply forked. Indusium very 
fragile, Peru, Pavon. Described from a type specimen lent by 
Mr. H. C. Levinge, in 1885. 
12. C. mexieana, Schlecht. So far as I can judge from sterile 
fronds, the plants which have been widely spread in gardens 
under the names of Alsophila Malzinei and A. Vangeerlii, are 
forms of this species.
