418 ENUMERATJO FILICUM PHIUPPINARUM. 



Hymenophyllum, Sm. 



262. H. bivalve, Forst. — Luzon; («. 221, 264.) 



263. H. Jimhriatum, J. Sm. — Luzon; (n. 218.) 



Obs, Very like Htjmenophyllum Jlexuosum of A. Cunning- 

 ham, from New Zealand, but differs in the margin of the 

 indusium being fimbriate. 



264. H. sanguiolentum, Sw.— Luzon ; (n. 129, 220.) 



265. H. nitens, R, Br.~Luzon ; («. 212.) 



266. H. dilataium, Sw — Luzon; (n. 112.) 



Obs. The specimens of the above species are certainly not 

 specifically distinct from New Zealand specimens. 



Sect. IV. DicksonicB, J. Sm. 



SiTOLOBiuM, Desv. 



(Dicksonia, Presl, non UHeritier. — Patania, Presl.) 



267. S.Jlaccidtim. — Dicksonia Haccidai Sw. — Luzon; («. 

 108, 145, 232.) 



268. S. cuneatum, J. Sm. — Luzon; {n. 231.) 



Obs. I also place in this genus Dicksonia glufinosa, Wall., 

 Dickso7iia pilosiuscula, Willd., Dicksonia dissecta, Sw., Dick- 

 sonia adiantoides, Humb., and some other species. 



CiBOTi UM, Kaidf. ; J. Sm. 



2G9. C. glanciim. — Dicksonia glauca, Sm. in Bees' Cyclop, 

 and Herb. Linn. Soc.-— Luzon ; (n. 123.) 



Obs. This is probably scarcely distinct from the fern culti- 

 vated in our gardens under the name of " Polypodium Baro- 

 mez" which is understood to be a native of China ; and ac- 

 cording to the fertile specimen which I have seen, the sori 

 appear, as in the present specimens, to be solitary on each 

 side of the base of the laciniae forming a row on each side 

 of the midrib of the pinnae, in that respect differing from an 

 allied species from Mexico (Cibotium Schiedei) which has the 

 sori seated round the margin of the laciniee.
