to subtruncate, the edge cut ^/j — '/I'^'^^Y down info blunt or subtruncate, 

 spreading or suberecto-patent lobes + 5 m.M. broad, subentire, or crenate 

 or toothed at the apex, lower pinnae + narrowed at the base; reduced 

 pinnae few, distant. Texture papyraceo-herbaceous ; under surface naked or 

 nearly so, verruculose; rachis slightly villose ; main veins pinnate in the lobes; 

 veins 6 — 11 on each side, the 2 — 3 lower ones anastomosing. Sori medial 

 or lower on the veins, to ± 6 on a side.

Rhizome ± erect. Stipes tufted, 15 — 45 c.M. long, villose at least on 

 the inner side. Fronds 20 — 45 c.M. long, 8 — 25 c.M. broad. Pinnae distant, 

 spreading, 5—15 c.M. long, 5 — 15 m.M. broad, the apex acuminate, the edge 

 cut + ^l^-wdiY down into oblong, more or less bluntish, slightly falcate lobes, 

 the base obtuse, lower pinnae reduced to mere auricles. Rachis villose ; 

 texture herbaceous to semicoriaceous ; under surface finely villose ; main 

 veins pinnate in the lobes; veins 3 — 4 on a side, the lowest pair anasto- 

 mosing. Sori nearly terminal or medial on the veins. — A plant gathered in 

 Borneo by Dr. Nieuwenhuis and determined by Dr. Christ (Ann. Btz., XX, 

 107) has the pinnae erecto-patent, with the base cuneate, the surfaces deci-. 

 duously hispid especially on the costae and edges, the lowest veins joining 

 at or a little below the tops of the sinuses, the lobes strongly erect as in 

 D. calcarata, 0. Kize, but less deep and the rhizome short-creeping.

Rhizome short-creeping or suberect, clothed with ovate-lanceolate, brown 

 scales. Stipes + tufted, 30 — 60 c.M. long, densely (deciduously ?) villose, the 

 base glossy and scaly. Fronds ovate-lanceolate, 30 — 90 c.M. long, 20 — 40 c.M. 

 broad. Pinnae linear-lanceolate, sessile, acuminate, more or less narrowed 

 towards the base, 1 — 2 c.M. broad, the edge cut ^2 — ^U down into linear- 

 oblong, subfalcate lobes to 4 m.M. broad, lower not-reduced pinnae deflexed; 

 below this several distant, abruptly dwarfed pinnae occupying the upper half 

 of the stipe, sometimes changed into glands. Texture herbaceous, firm, rachis
