60 — 100 c.jVI. long, acuminate, 4 — S-pinnatifid. Pinnae and lower pinnulae 

 long-acuminale, deltoid-ovate, the higher ones narrower. Ultimate segments 

 lanceolate or oblong, serrate or incised. Texture hardly coriaceous; surfaces 

 + naked ; penultimate rachises winged ; no spurious veins. Sori flanked mostly 

 by 1 — 2 teeth; indusium semicylindrical, conspicuously rostrate. — Fronds 

 resembling D. solida, Sw. k divaricata, Bl. 

 Luzon, Mindoro.

Rhizome wide-creeping, the scales small, shining, linear, acuminate, cas- 

 taneous. Stipes naked, erect, slender, castaneous, 50 — 45 c.M. long. Fronds 

 oblong-deltoid, decompound, 50 — 4S c.M. long, + 15 c.M. broad. Pinnae 

 distant, deltoid, staHied, erecto-patent, many of the lower ones subequal, 10 — 15 

 c.M. long by half as broad. Pinnulae and tertiary divisions subpetiolate, 

 rhomboidal, the base cuneately cut away on the lower side. Ultimate lobes sub- 

 remote, ligulate or rather broader towards the truncate apex, + 1 — 5'/2m.M. 

 long, + 72 ™-^^^- broad, with only a single central vein, the apex denticulate. 

 Texture subcoriaceous ; surfaces naked. Sori small, oblong, usually immersed 

 in the tips of the segments.

Rhizome creeping, densely clothed with fuscous, lanceolate, + adpressed 

 scales, which are whitish at the apex and the edge. Stipes remote, + 1^4 

 c.M. long, naked, narrowly winged. Fronds deltoid, ± 10 c.M. long, + 6 

 c.M. broad, the rachis fui'cato-alate on the upper side. Pinnae ascending, + 

 straight, narrowly ovate, the lowest largest, broadly ovate, falcate, slightly 

 deflexed. Pinnulae minute, cuneate, cut down to the costa into narrow, long- 

 subulate, rather hair-like segments. Texture coriaceous; surfaces naked; no 

 spurious veins. Sori on the ultimate segments, flanked by a horn on each 

 side; indusium semicylindrical, marginal.

Rhizome stout, wide-creeping, the scales brown or pale-brown, with the 

 base roundish, peltate, adpressed, the apex long-acuminate, recurved, spreading, 

 ciliate, at length deciduous, giving the rhizome a woolly appearance when
