TAKEDA—ASIATIC POLYPODIUMS, 283 
n. 17); Thae-pei-san, Shenshi septentrional (Giraldi, Aug. 
1896 *). 
It is quite possible that P. Soulianum, Christ,+ none of the 
authentic specimens of which has been examined by the writer, 
is a form of P. clathratum, Clarke. 
The writer prefers to leave out remarks upon the Indian 
specimens of this species, and only refer to Hope’s paper.{ 
12. P. boninense, Christ.§ 
This species probably comes midway between P. excavatum 
and P. clathratum. The frond is, however, thicker and more 
rigid. The sori are immersed, round or slightly oblong, and are 
situated almost midway between the midrib and margin. 
Despite the thick and coriaceous texture of the frond, the costules 
are prominent, at least in dried specimen 
e ramenta are ovate-lanceolate, dark brown, clathrate, 
and ciliate-denticulate on the margin. 
So far, this species has not been known to occur except in the 
Bonin Islands. The writer has seen the specimens collected by 
Wright in 1853-56. Besides these there are at Kew a few 
_ specimens of this species sent from the Imperial Academy, St. 
Petersburg (n. 41), which bear no collector’s name. 
13. P. asterolepis, Baker. 
There is some confusion in nomenclature of this species 
The first name given to this species is P. asterolepis, Baker (1888). 
Baker erroneously reported this name in Annals of Botany, v 
p- 474 (1891) as P. aspidiolepis, probably mixing it up with P. 
aspidiolepis, Bak. from Costa Rica. Christ, in 1905,when reducing 
this species to P. simplex (=P. excavatum), adopted Baker’s mis- 
reported name, and called it P. simplex var. aspidiolepts, Christ. 
Meanwhile the same species was described by Baker as P. 
macrosphaerum in 1895, and again in 1906 as P. intramarginale. 
The full synonymy of this species will therefore be given in order 
to make the matter clearer :-— 
P. asterolepis, Baker in Journ. Bot. xxvii, p. 230 (1888). 
Syn. :—P. excavatum var. asterolepis, C. Chr. Ind. Fil. p. 511 
(1906). 
P. aspidioleprs, Bak. in Ann. Bot. v, p. 474 (1891), by error. 
The specimen has been determined by Christ as P, oligolepidum. See Nuov.
