deep. Texture coriaceous; the edges and midrib Jieneath very sparingly 

 covered vsrith distant, minute, inconspicuous, blackish-brown hairs; veins hid- 

 den, pinnate w^ith 1 — 3 veinlets on each side, which are very rarely joining 

 at the apex. Sori round, ± elliptical when young, nearly superficial (very 

 slightly and indistinctly immersed), in 2 — 5 + irregular rows on each side 

 of the midrib. — Beccari's and Raciborski's plants in the Buitenzorg her- 

 barium are quite the same plants.

Rhizome short, the scales membranaceous, dense, ferrugineous, narrowed 

 gradually from the base to the apex, the edge entire. Stipes tufted or ap- 

 proximate, short, clothed like the whole frond with long, spreading, red-brown 

 hairs. Fronds 10 — 15 c.M. long, once or more times forked, tapering very 

 gradually into the slender stipe. Segments of the fronds linear, 2 — 3 m.M. 

 broad, with a gradually narrowed apex. Texture coriaceous; veins hidden, 

 short, forked. Sori in 1 row on each side near the costa, large, alternate, 

 nearly confluent, filling up the whole under surface of the ultimate segments.
