(28^)) Pt. silvatiea, v. A. v. A. 



Rhizome creeping, tliick, the scales subulate, fuscous, deciduous. 

 Stipes pluriseriate, approximate, to 75 cm. long, rufo-fuscous and sparingly,, 

 minutely punctulato-asperulous, as are the rachis and the costae beneath, 

 sparingly and deciduously scaly towards the dark-castaneous base. Fronds 

 ± 35 — 45 cm. long. Pinnae about 5 — 6 on a side below the terminal 

 one; terminal pinna lanceolate, ± 15 cm. long by 4—5 cm. broad, the 

 edge cut down to a proportionally broad wing to the costa, the apex sub- 

 ulate-caudate and serrulate; lateral pinnae similar but the lower growing 

 gradually larger, to 30 cm. long, to 6% cm. broad at the middle, sub- 

 spreading to suberect, the lower petiolate, the lowest forked on the lower 

 side at the base. Lobes oblique, straight or subfalcate, close or somewhat , 

 remote by the slightly dilated bases, those on the posterior side sometimes 

 larger than the anterior ones, to S'/i cm. long, ^4 — 1 cm. broad at the 

 base; barren lobes serrulate-crenate in the lower part, serrulate at the 

 blunt or rounded apex; fertile lobes serrate-dentate at the barren apex. 

 Texture herbaceous; surfaces naked; costae stramineous and shortly 

 remotely spinulose above; veins forked, the higher simple, the lower 

 sometimes twice forked. Sori not occupying the upper V4 — Vj of the 

 lobes. — Pt. longipinnula Wall. var. sumatrana is an irregularly lobed 

 form of this only.

Scales of stipe and rachis at length deciduous ; pinnae not rarely very 

 rigidly coriaceous, with the edge often much and irregularly recurved or 

 reflexed, the base rounded, truncate or cordate; veins distinct, prominent 

 beneath. — A form gathered in Luzoyi (Robinson, Bur. of Sci. No. 6499) 

 has the pinnae very blunt, and crenulate. Perhaps a distinct species..
