from Tahiti (Vesco). 9. P. crassifrons, Baker, Syn. Fil., from New Caledonia (Deplanche). 10. P. sub- 
nudum, Mett. Linnwa, 1869, p. 130, from Society Islands, Huahine (Capt. Cook !), Tahiti (Collie! Barclay ! 
n. 3827, Vesco, Riebourt). This is a true Polypodium, which has been confounded in herbaria, as Mette- 
nius states, with Davallia contigua. Indeed, at page 338, I erroneously referred Capt. Cook's specimen to 
that species. It may, however, be only a Polypodioid state of the Davallia, in which the indusium is almost 
entirely aborted, and forms only a slightly-raised ridge on the inner margin of the sorus. The sporangia 
are very short-stalked, grouped in roundish oval sori on the under surface of the pinnules, and extend often 
along thé margins of the pinnule to its very base; while in Davallia contigua they are confined to the upper 
half of the pinnule. The rachis is green, not dark, and less setose also than in the Davallia. 11. P. lasio-
