(7) P. caespitosum (Blume) Mett. Stipes clustered on a very short 

 chaffy rhizome, 2 to 4 cm. high, wiry, weak, clothed with short weak hairs; 

 fronds 8 to 15 cm. long, rather over one-twentieth as broad at the middle, 

 gradually narrowed toward both ends, entire, subcoriaceous, usually quite 

 glabrous; veins as a rule twice forked, inconspicuous; sori somewhat 

 immersed, oblong, oblique to the costa. 



Mount Apo, 1,800 m. CopeJund 1008a, 1009, 1010. 



Java. 



A very variable species, especially in the texture and venation, and 

 the shape and direction of the sori; a form occurs rarely with two 

 irregular rows of sori on each side of the costa. 



(8) P. fasciatum Mett. Rhizome strong, wide-creeping, clothed with 

 broad gray scales; stipes 2 to 5 cm. high, rigid, deciduously ciliate, frond 30 

 cm. or more long, 1 cm. broad narrowed gradually toward both ends, entire, 

 coriaceous, glabrous; costa prominent, veins immersed, forked; sori super- 

 ficial, oblong, arranged end to end close to the costa. 



Mount Data 2,2.50 m., Loher; a dwarf form, scarcely 7 mm. high, with 

 stipe almost naked. 

 Malaya. 



(9) P. sessilifolium Hooker. Fronds tufted, 7 to 22 cm. long, 4 to 6 

 mm. broad, narrowed gradually below the point, bluntish, entire or slightly 

 undulate, subcoriaceous, glabrous; veins forked; sori oblong, placed end 

 to end close to the costa.

 ^Malaya. 



(10) P. pleiosoroides Copeland. Rhizome short, creeping, its scales 

 broadly lanceolate, acuminate, stramineous; stipe 2 to 4 cm. high, slender, 

 densely beset with very short stramineous hairs; frond 10 to 15 cm. high, 

 one-tenth as broad, lanceolate, contracted to both ends, coriaceous, glabrous, 

 margin sinuate, especially toward the base, bearing a few short hairs; 

 veins immersed, inconspicuous, about 4 times forked; sori large, round, 

 superficial, in 1 to 3 irregular lines or altogether scattered. 



Mount Apo, 1,800 m., Copeland 1011, epiphytic. 



(11) P. loherianum Christ, Bull. Herb. Boiss. 6(1898) :197. Rhizome 

 short, with purplish hairs; stipes clustered, I to 3 cm. high, naked; frond 

 ligulate-lanceolate, 15 cm. high, 7 to 10 mm. broad, rather obtuse, gradually 

 contracted to the base, crenate-dentate, the teeth of irregular width, 3 

 mm. or less deep; nervature inconspicuous, veins pinnate in the teeth; sori 

 dorsal on the lowest acropetal veinlets, scarcely immersed, round or oval, 

 in a row rather nearer the costa than the margin, rarely a second imperfect 

 row present; texture coriaceous. 



Mount Data, 2,250 m., Loher. 



(12) P. cucullatum Nees. Rhizome short, scaly; fronds very densely 

 tufted, nearly sessile, 7 to 15 cm. long, about 7 mm. broad, but little 

 contracted toward the ends, flaccid, glabrous or nearly so, pinnatifid to 

 the winged rachis into numerous obtuse segments 1.5 mm. broad, separated 

 by less than their own breadth, each with a single conspicuous vein;
