Rhizome stout, creeping, the scales linear-lanceolate, reddish. Cup-leaves 

 10 — 25 c.M. long, 7 — 10 c.M. broad, cut '/2 — ^/i^way down into bluntish or 

 acute lobes. Fertile fronds 40 — 90 c.M. long, often 50 c.M. broad, with a 

 distinct stipe, the lobes 10 — 15 c.M. long, 1—2 c.M. broad, reaching down 

 nearly or quite to the costa, crenate, slightly toothed or undulato-crenate; low- 

 est lobes decurrent. Texture subcoriaceous ; surfaces naked; areolae copious, 

 with free veinlets. Sori in a single row on each side, near the midribs. — 

 Very near D. pleuridioides, J. Sm. 



Var. isunisitrana : Sori very large, nearly medial.

Near D. quercifolia, J. Sm. Rhizome 5—10 c.M. thick, the apex mam- 

 miform, the scales peltate, aristate, caducous. Cup-leaves 5 — 10 c.M. long, 

 dry, hard, ovate, slightly crenato-lobate, brown, or grey beneath, the base 

 cordate with the basal lobes overlapping. Stipes of fertile fronds winged, 

 the wing consisting of the lower, reduced lobes. Fertile fronds 40—60 c.M. 

 long, deeply lobed or pinnatifid. Lobes to 10—20 c.M. long, ± I'/i— 2V2 

 c.M. broad, acuminate, crenate, slightly narrowed at the base, connected by 

 a wing ± 4 c.M. broad. Texture papyraceous; surfaces naked.

* (4) D. quercifolia, jr. Sm., Bedd., Handb. Ind. Ferns, 541;

Rhizome stout, ascending, densely clothed with narrow, linear-subulate, 

 eroso-ciliate ^scales, which are narrowed gradually and rather regularly from 

 the rounded, peltate base to the point. Cup-leaves 7V2 — 30 c.M. long, 5 — 15 

 c.M. broad, rigid, bluntly lobed often V2-way down. Fertile fronds 60—150 

 c.M. long, 50 — 40 c.M. broad, deeply pinnatifid nearly to the costa, on stipes 

 to 30 c.M. long. Lobes entire, erecto-palent, linear-lanceolate, blunt, acute or 

 acuminate, 1—4 c.M. broad, the lowest not rarely short, often suddenly de- 

 current so as to form a wing reaching not rarely to the base of the stipe.
