 Found also on the adjacent continent, extending into the 

 extreme west of the empire ; occurs likewise in Java, the Phi- 

 lippines, and Ceylon. Mr. Bentham unites A. mtermeAi/wm, 

 J. Sm., with A. sultriphyllam, from which it is altogether dif- 

 ferent. I have the distinct authority of the late Professor Met- 

 tenius and Dr. Max Kuhn for the Chinese fern being referable 

 to Kunze's species, as shown by his herbarium. 



*Pol3rpodiuin lineare, Thumb. ; Mett. in Miq. Ann. Mus. Bot. Lugd.-

 This is as inseparable from Poh/poditim as Meniscium is from 

 Aspidium. Sir W. Hooker referred it to Crymnogramme, which, 

 as limited by him, is a most heterogeneous assemblage. The 

 true species of that genus have the stipes continuous with the 

 rhizome.

 nodes. Wall. ; Benth. Fl. Hongk. 458.) 



*Poljrpodiuin varium, Mett. Monogr. Polypod. 126. ( = P. adnascens, 

 Benth. Fl. Hongk. 458, but not of Swartz.) 



*Nephrolepis hirsafalii, Presl, Tent. Pteridograph. 79. (= Aspidium 

 exaltatum, Benth. Fl. Hongk. 453, part., but not of Swartz.) 

 The much denser indumentum, and longer, less falcate and 

 less auriculate overlapping pinnsB, with the sori more crowded, 

 and placed nearer the margin, seem to distinguish this speci- 

 fically from JVt exaltata, Schott. 



*Nephrolepis tuberosa, Presl; Hook. Sp. Fil. iv. 151, part. (=Aspi- 

 dium exaltatum, Benth. Fl. Hongk. 453, part.) 

 The above two ferns are unquestionably quite distinct, and 

 easily recognizable at sight, being quite dissimilar in appearance 

 when alive : the pinnse of the latter are not half as long, paral- 

 lelogrammatic in outline, rigid, about the same length through- 

 out the whole frond, and almost smooth, with submedian sori. 

 JT. delicatula, Dene., looks different from this. So far as my ob-
