TAKEDA—ASIATIC POLYPODIUMS. 295 
Formosa. Tamsui district (Hancock, n. 23, 100,* Oldham, 
n. 58), Posia (Steere), Sao bay (Murphey). 
25. P. triglossum, Baker.+ 
A species probably most closely allied to the preceding and 
also to P. hemionitideum, Wall. From the trifid form of the 
former it differs by the larger sori, the presence of ovato-lanceolate 
and strongly dentato-ciliate scales on the under surface of the 
frond, by the strongly dentate and clathrate peltate scales in 
the sorus, and by the veins not forming distinct series of areoles, 
From the other species it differs by the presence of scales in the 
sori, thinner and flexuose costules, less distinct veinlets, and 
the trifid frond—which last point may not be very important. 
In the original description it is stated that the sori are 
uniseriate, but in fact they show a tendency to become biseriate. 
The author is also wrong in placing the present species near 
P. trifidum, Don; these two species have no close relationship 
whatsoever. 
I have only seen the type specimen from Milé, Yunnan, 
collected by Henry (n. 9953). : 
26. P. trisectum, Baker. 
This is a very distinct species, being well characterised by 
the presence of short glandular hairs § on both surfaces of the . 
frond, although this important character is not mentioned in 
the original description. The frond varies from trifid to pedate, 
and the terminal segment sometimes shows the: tendency to 
produce additional lobes, the frond thus becoming subpinnatifid. 
Its margin is thickened and provided with very shallow notches. 
The first name given to this species is P. trisectum, Bak..,|| 
and the second one is P. fodobasis, Christ.§{ Christ has also 
given a name P. accessorium, which, so far as the writer has been 
able to ascertain, has not been published. 
This species is exclusively Chinese ; I have seen the following 
specimens :—Yunnan : Milé district, in. woods (Henry, n. 9891) ; 
Szemao, W. mts., 5000 ft. (Henry, n. 98914, 13,12IA, 13,121B) ; 
“Col de Pi iousé”’ (Delavay, Sept. 1888). 
The specimen recorded by Christ as P. podobasis in the Bull. 
Acad. Intern. Geogr. Bot. xvi, p. 106 (1906) is not identical with 
* The type specimen of P. Hancockii, Bak.
