208 TAKEDA—ASIATIC POLYPODIUMS. 
Province of Hupeh.* Later, Christ enumerates the same name 
in the List of the Ferns collected by E. H. Wilson in Western 
China. 
A careful examination of these two specimens above-men- 
tioned has shown that they do not represent the real P. malacodon, 
but P. Stewartii, Clarke. Unfortunately I have been unable to 
examine other specimens referred to P. malacodon by Christ, 
so that I cannot speak with certainty regarding the correctness 
‘of the identifications. 
However, I have seen a specimen of the true P. malacodon, 
Hook. from Western China,t which has been known as 
austrosinicum, Christ,§ or P. albido-glaucum, C. Chr.|| Another 
specimen of P. malacodon I have examined was collected in 
Yatung, Tibet.4 
30. P. Stewartii, Clarke.** 
s has been alluded to under the preceding species, some 
_ specimens of P. Stewartii have erroneously been recorded from 
China as P. ma/acodon. Although these two species are closely 
related, P. Stewartit can be distinguished from the other above 
all by the nature of the serration, which is not cuspidate-pointed 
as in its ally, and by the direction of the lowest pinnae, which 
are deflexed, while those of P. malacodon are invariably falcate 
and curved towards the apex of the frond or erect patent at 
most. 
The occurrence of P. Stewartii in China has also been reported 
by Christ,++ who, on this occasion, reduced it to P. malacodon as 
a variety. I have not seen any of the specimens referred to by 
that pteridologist, so that I am not quite sure as to their correct 
identification. 
The following specimens have been examined from China :— 
_~ Hupeh (Henry, n. 6170£). Szechwan: Mt Omei (Wilson, 
N. 5333). Tibet: Yatung (Hobson, 1897). 
23\° 37. P. cyrtolobum, Clarke. 
In connexion with P. malacodon and other species of this 
group, I may perhaps say a few words about P. cyrtolobum.

given as P. malacordon, Kooh., which is, however, Ree meant by that 
author for P. malacodon, Hook. t
