Arayat, Luzon, by the Bolster (Nos. 79, 98.) The rhizome seems to be 
very slightly creeping, the sori are submargina.1 at the anterior base of 
the lobes and the textnre of the plant is rather thin and not coriaceous 
as in specimens of Aspidium vile from Java leg. Raciborski. After 
examining the material at present available, I do not consider that this 
doubtful species can be referred with certainty to Dryopteris. 
4. Aspidium variwn Sw., is to me a Polysticlium, and for this reason 
this Chinese type, which is also found in northern Luzon, is not con- 
sidered in the'following list : 
DRYOPTERIS Adanson.
