1911] CHRIST—FILICES WILSONIANAE 355 
latis, lobis ovato-rotundatis acutis interdum dentatis. Soris 
magnis, singulis in lobis, demum confluentibus, indusio inconspicuo 
corrugato. Textura tenuiter herbacea, colore laete virente. 
Has.—Rocks, Fang Hsien, 8000 ft., June 27, 1907, W. Hupeh, no. 2657. 
An extremely reduced species, with the habit of a very small Cystopfteris, 
distinguished from P. capillipes (Baker) Diels by the less incised pinnae with 
broader segments. 
With the six species here described, with which Mr. Wilson has enriched 
the flora of China, the Chinese species of Polystichum now known number 52. 
There are few examples of so rich and continuous a development without 
gaps between the different known forms of this genus, so essentially Chinese. 
The species of Polystichum of other regions of the globe seem to be only deriva- 
tives or scattered offshoots of this great eastern center. 
Gymnopteris Sargentii H. Christ, n. sp—Rhizomate valido 
pollicis crassitie, obliquo, setis mollibus o.5 cm. longis pallide rufis 
densissime obtecto, radicibus numerosis fasciculatis. Stipitibus sub- 
fasciculatis 3 aut 4, flexuosis crassis rigidis 3 mm. diametro, rufo- 
stramineis, 8 cm. longis, cum rachi aeque rigida et 2 ad 2.5 mm. 
crassa costisque tomento albido-fulvo omnino-vestitis, lamina late 
deltoideo-ovata 20 cm. longa 9 cm. lata abunde bipinnata, pinnis 
remotis ca. 6 utrinque infra apicem brevem simpliciter pinnatum, 
€recto-patentibus, infimis suboppositis coeteris alternis, basalibus 
aud abbreviatis, 7 cm. longis 14 mm. latis, lineari-lanceolatis 
breviter petiolatis, costa rigida vix 1 mm. crassa, pinnulis ca. 7 
utrinque, approximatis, deltoideis obtusis basi late trilobo-hastatis 
7 mm. longis 5 mm. latis petiolulatis, rigide coriaceis, supra calvis 
obscure viridibus, subtus et margine densissime rufotomentosis 
nitidis. Soris submarginalibus confluentibus. 
Has.—Loamy places in warm valleys, Monkong Ting, W. Szech’uan, 
7000-9000 ft., June 28, 1908, no. 2669. 
This is the most developed species of the series formed by the three species 
G. vestita (Grammitis Wallich) Underw., G. bipinnata Christ (Notul. Systemat. 
Mus. Paris no. 2, p. 23. 1909), and G. Sargentii, distinguished by its larger 
dimensions, and a broadly bipinnate frond with numerous trilobed pinnules. 
Habit nearly that of Pellaea hastata (Thnbg.) Prantl. G. bipinnata differs 
by the slender rachis, elongated lanceolate pinnate to nearly bipinnate fronds, 
and less incised pinnules.
