48 POLYPODIUM, § NTPHOBOLUS, 



(fronds almost glabrous), n. 203; Malay Archipelago and Islands, De Vriese 

 (Java), n. 316, 495; Amboyna (IFebb), Griffith, Wallich, Cuming, n. 135, 240, 

 67, 88, and 93 ; Ceylon, Gardner, n. 1153. China, Fiji Islands, etc. West tro- 

 pical Africa; Cameroons, G. Mann. — A very universally distributed Fern, espe- 

 cially over the continent of India and adjacent islands, well distinguished by nu- 

 merous sori, deeply sunk in a cavity of the frond, and arranged in transversely 

 oblique series between the costa and the margin. 



306. P. (Niphobolus) spissum, Bory; "caudex creeping 

 clothed with ferruginous ovato-lanceolate acunainated scales 

 their base appressed recurved at the apex, fronds coriaceous 

 glabrous above, beneath clothed with stellated at length ru- 

 fescent scales; sterile ones 1-4 inches long oblong or linear- 

 lanceolate obtuse or acute, secondary veins subm.anifest, 

 areoles with three free veinlets immersed the petiole 2-8 

 lines long; fertile ones 4 inches long from a long attenuated 

 base linear rather obtuse soriferous upwards the petiole 4 

 lines long, sori immersed impressed protuberant at the back 

 on each side the costa 3-4-seriate at first annular." [Metten.)

Hah. " Bourbon, Boivin." — Perhaps allied to P. adnascens. 



307. P. (Niphobolus) porosum. Wall.; caudex creeping 

 subulato-paleaceous with ferruginous scales, stipites aggre- 

 gated short scarcely any or 3-5 inches long and then winged 

 or margined to the base, fronds carnoso-coriaceous 6 inches 

 to a foot and more long \ an inch to 1-H wide lanceolate or 

 linear-lanceolate or even linear often finely acuminated the 

 margin quite entire or spuriously and very unequally pinnatifid 

 with remote long and narrow segments, from near the middle 

 gradually attenuated downwards to the caudex at first wholly 

 tomentose with deep ferruginous stellated hairs at length 

 glabrous on the upper side and depresso-punctate the dots 

 corresponding with the sori, venation quite sunk and ob- 

 solete, sori very copious and at first quite sunk among the 

 tomentum appearing in the form of small tubercles, at 

 length a circular opening appears but the sori scarcely rise 

 above the surface of the tomentum arranged indeed in series 

 but it is impossible to say how far these series are confined 

 within certain areoles. — Wall. Cat. n. 266. Metten. Polyp.
