linear, subacute, 5 m.M. broad, separate, the sinuses rounded, the higher lobes 

 close, the edges lobato-crenate, the teeth obtuse, ± 8 on each side, + 1 

 m.M. each way. Gestae and veins subfurfuraceous or naked. Sori near the 

 costulae, in the forkings of the veins, 6—8 on a side. — See Copeland's in- 

 formation, 1. c. — Luzon. 



* (5) V. ^i^atntea, Pr. — Omit as synonyms: P. Trimeni, Bedd. 

 and Sagenia giyantea, Moore. — P. Trimeni, Bedd. is a distinct species and 

 Sagenia gigantea, Moore its synonym. 



(7) P. Bakeri, v. A. v. R. — Omit this name, it should be P. Trimeni, 5erfc?.

Stipes tufted, 50 — 60 c.M. long, grey or brown; basal scales linear. 

 Fronds 30—90 c.M. long, deltoid or deltoid-lanceolate, pinnatifid at the apex, 

 below pinnate with ± 5 — 6 lateral pinnae on each side, which are more or 

 less stalked and all pinnatifid more than V2""^^y down to the costa. Lowest 

 pinnae largest, pinnate at or towards the base, with the lower (lowest) basis- 

 copical pinnulae prolonged and deeply pinnatifid. Ultimate lobes bluntish, 

 slightly crenate or nearly entire. Texture rather thin, both surfaces naked; 

 costae and veins ± rusty above, less so or rather naked beneath ; veins form- 

 ing 1 — 2 rows of areolae near the midribs, the rest free, no included free 

 veinlets. Sori in 1 row on each side of the costulae; indusium subcordate, 

 reniform. — A from found in Sumatra by Dr. Burck has the rhizome erect, 

 densely clothed with long, linear-subulate, fuscous scales, the stipes and ra- 

 chises sparingly fibrilloso-paleaceous, the ultimate lobes blunt to subacute, 

 entire to broadly toothed.
