142 DR. H. F. HANCE’S SUPPLEMENT TO 
mainland, in the mountainous regions of India, the Malay archi- 
pelago, the Philippines, and some of the Pacific isles. 
72. Aspidium devexum, Kze.; Mett. in Miq. Ann. Mus. Bot. Lugd.- 
Bat. i. 237. (=A. intermedium, J. Sm. ; Mett. Monogr. Aspid. 119.

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 4. intermedium, 
J. Sm., with 4. subtriphyllum, 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. 
*Polypodium lineare, Thunb.; Mett. in Mig. Ann. Mus. Bot. Lugd.- 
Bat. ii. 224, (=P. Wightianum, Wall.; Benth. Fl. Hongk. 458.) 
*Polypodium ellipticum, Thunb.; Mett. in Mig. Ann. Mus. Bot. 
Lugd.-Bat. ii. 225. (=Grammitis decurrens, Wall.; Benth. Fi. 
Hongk. 457.) 
This is as inseparable from Polypodium as Meniscium is from 
Aspidium. Sir W. Hooker referred it to Gymnogramme, which, 
as limited by him, is a most heterogeneous assemblage. The 
irue species of that genus have the stipes continuous with the 
rhizome. 
*Polypodium superficiale, Blume; Hook. Sp. Fil. v. 71. (=P. hyme- 
nodes, Wall. ; Benth. Fl. Hongk. 458.) 
*Polypodium varium, Mett. Monogr. Polypod. 126. (=P.-adnascens, 
Benth. Fl. Hongk. 458, but not of Swartz.) 
*Nephrolepis hirsutula, 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 aurieulate overlapping pinnz, with the sori more crowded, 
and placed nearer the margin, seem to distinguish this speci- 
fically from N. exaltata, Schott. 
*Nephrolepis tuberosa, Presi; 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 pinne of the latter are not half as long, paral- 
lelogrammatie in outline, rigid, about the same length through- 
out the whole frond, and almost smooth, with submedian 801: 
N. delicatula, Dene., looks different from this. So far as my ob-
