54 POLYPODIUM, § NIPHOBOLUS. 



Hab. Island of Tsus-Sima, Gulf of Corea, growing on rock, Wilford. — A 

 very remarkal)le plant, quite unlike any other Fern of this group known to me ; 

 well represented in the work above quoted. 



318. p. (Niphobolus) nummulariiefolium, Metten.; caudex 

 very long filiform copiously rooting paleaceous with appressed 

 setaceous ferruginous scales, fronds dimorphous carnoso-co- 

 riaceous subglabrous above beneath densely clothed with 

 ochraceous or subferruginous stellated tomentum ; stei^ile 

 fronds (on petioles 1-3 lines long) ^ to 1 inch long orbicular 

 or elliptical or subcordate; fertile ones (on stipites 1-1 ^ inch 

 long) H-2 inches long \ of an inch wide linear or linear-ob- 

 long obtuse, " areoles immersed in 3-4 series including one 

 free veinlet," Metten., sori scarcely sunk apparently covering 

 the whole back of the frond without order. Metten. Polyp,

Hab. Java, Thunberg, Blume. Luzon, Cuming, n. 246. Assam, Khasya (alt. 

 2000 feet), Mishmee, Griffith, Hooker fil. and Thomson. — A distinct and well- 

 marked species. 



319. P. (Niphobolus) obovatum, Metten.; "caudex creep- 

 ing clothed with lanceolato-subulate scarcely ciliated reddish 

 subpatent scales, fronds glabrous above below densely ad- 

 spersed with stellated hairs ; sterile fronds 6 lines long ob- 

 ovato-oblong attenuated into a stipes 2 lines \or\g; fertile 

 fronds 8 lines long spathulato-oblong obtuse with 6 lines 

 long, veins immersed ?, sori not impressed." — Metten. Polyp.

Hab. Java, Blume, Zollinger. — This species is unknown to me, but some of my 

 specimens of P. nummular iccfolium seem undistinguishable from it; the stipites 

 vary much in length. 



320. P. (Niphobolus) Americanum, Hook.; caudex thick 

 but evidently creeping, stipites aggregated 1-3-4 inches long, 

 fronds li-2 feet and more long ^-| of an inch wide hard- 

 coriaceous linear-elongate acuminated long-tapering below on 

 the stipes glabrous and glossy above densely stellato-tomen- 

 tose and tawny and subfurfuraceous beneath, costa stout pro- 

 minent beneath, venation ?, costules obliquely patent as indi- 

 cated by the fructifications of which a single series of rather 

 large oval sori occupy the space between the costules.
