Monogramme paradoxa (Fee) Becld. (M. Junghuhnii Hook.) is cred- 
ited to Formosa by Harrington, but the label of the specimen sent me 
reads “Growing in tufts on trunks of trees, Philippine Islands.” The 
determination is correct, and this species should probably be added to our 
known flora. 
Polypodium craterisorum Harrington is unmistakably P. celebicum 
Blume. It is described in error as membranous- (1. c., p. 32). Elmer 
(Ho. 7760) has collected this fern on Mount Banajao (which is Mount 
Majayjay). Some of the fronds are contracted below so abruptly as to 
suggest its relative, P. decrescens Christ. 
Polypodium liammatisorum Harrington turns out, as 1 8 have antici- 
pated, to be identical with P. nummularium Mett. 
Polypodium Schenldi Harrington is, as stated by Baker, 9 our common 
P. oibliquatum Bl.
