214 FERNS OF WESTERN SUMATRA. 



base, very thick and coriaceous in texture, almost naked on both 

 sides, but the edge ciliated with a few very minute black hairs. 

 Veins forked, free. Sori orbicular, slightly immersed, placed in a 

 single row near the thick midrib in the upper half of the frond a 

 short space from one another. Mt. Singalan, 1700 metres. Near 

 the Oeylonese P. zeylanicum, Mett. 



448 (117*)- Polypodium (Eupolypodium) sumatranum, Baker, 

 n. sp. Rhizome short- creeping, epigseous, ^ in. diam. Scales 

 densely imbricated, pale brown, lanceolate. Stipes contiguous, 

 very short, why, erect, covered with minute brown pubescence. 

 Fronds ligulate, 6-12 in. long, f-f in. broad at the middle, sub- 

 coriaceous, glabrous, narrowed gradually to both ends, the edge 

 furnished with broad shallow rounded lobes. Veins in a pinnate 

 group opposite each lobe, the veinlets about three on a side, short, 

 erecto-patent, arranged like those of a Goniopteris, but not joining 

 at the tips. Sori copious, orbicular, superficial, placed a little 

 below the tip of the side veinlets, so that there are several irregular 

 rows between the midrib and edge. Mt. Singalan, 1700 metres. 

 An interesting novelty, nearly allied only to the Andine P. tricho- 



sorum, Hook. 



481. P. cucullatuui, Nees. With the last. 



P.fuscatum, Blume. With the last. 



441 (168*). P. nutans, Blume Fil. Jav., t. 86a. Rhizome 

 short-creeping, clothed with dense linear ciliated dark brown 

 scales. Stipes nearly tufted, 2-3 in. long, minutely pubescent. 

 Fronds lanceolate, 8-12 in. long, l-li in. broad at the middle, 

 narrowed gradually to both ends, moderately firm in texture, 

 thinly pilose on both sides of the lamina, more densely so on the 

 midrib, cut down to the rachis into very numerous adnate entire 

 linear pinnae |-f lin. broad above the dilated base. Veins 8-10- 

 jugate m the fully-developed pinnae, simple, erecto-patent. Sori 

 orbicular, superficial, filling up the whole space between the midrib 

 and margin. Mt. Singalan. Distinct from P. decorum, under 

 which it is noticed in < Synopsis Filicuni,' by its ciliated linear 



paleae, longer stipe, pilose frond, more numerous pinnse, and super- 

 ficial sori. 



P. obliqvatum, Blume. P. Schenhii, Harrington. Mt. Singalan, 

 1700 metres. 



443. P. celebicum, Blume. Mt. Singalan, 1700 metres. 

 P. verntcosum, Wall. Ayer Mancior. 

 415. P. pemccefolium, Desv. Mt. Singalan, 1700 metres. 

 P. adnuscens, Sw. Ayer Mancior. 



P. Lingua, Sw. Mt. Singalan, 1000 metres. 



458(290 :: ). Polypodium (Niphobolus) asterosorum, Baker, u.sp. 

 Kluzome slender, wide-trailing, epig^ous, clothed with large 

 lanceolate pale reddish brown membranous scales. Stipes distant, 

 naked, pale brown, 2-3 in. long. Fronds lanceolate, entire, 8-12 

 in. long, f-1 m. broad above the middle, acute, narrowed gradually 

 from the middle to the bane, coriaceous, glabrous on the upper 

 surface, whitish beneath, matted with loose soft reddish brown 

 stellate tomentum. Main veins very obscure, erecto-patent, about
