linear, subacute, 3 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. Costae 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.

Stipes tufted, 30 — 60 c.M. long, grey or brov^n; 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 oi 

 less stalked and all pinnatifid more than Va'^^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| form 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 subjacute, 

 entire to broadly toothed. -!f-^
