by Hooker as a complete frond. A specimen gathered by Mr. Whitford has 

 the fronds 5-pinnalifid, the pinnulae + 25(15 — 35?) c.M. long, etc., the ultimate 

 rachises marginate or rather narrowly winged.

Stipes stout, erect, + 45 c.M. long. Fronds 90—120 c.M. long, deltoid- 

 lanceolate, 4-pinnatifid. Pinnae 20 — 25 c.M. long, the lower ones deltoid-lan- 

 ceolate, lanceolate to linear-lanceolate upwards. Lower pinnulae + 6 — 7 c.M. 

 long, the others + 2^/2 c.M., cut down nearly or quite to the rachis into 

 oblong, broadly toothed lobes. Texture coriaceous; surfaces naked. Sori ter- 

 minal on thickened veins and exserted beyond the margin.

Rhizome creeping. Stipes 1 — 2 M. long. Fronds 3 — 4-pinnate, ovate- 

 deltoid, to 2^/2 M. long, to + 172 M. broad. Pinnae linear, opposite, short-

 base. Pinnulae sessile, to 8 c.M. long, to 2 c.M. broad, the base + truncate. 

 Tertiary divisions close, unequal-sided, to 1 c.M. long, to 4 m.M. broad, pinna- 

 tifid ^2 — '/4'Way down to the costa, the apex toothed, the base decurrent, 

 the lobes crenate or toothed. Texture herbaceous; both surfaces naked. Sori

Rhizome tortuose, the scales linear, fibrillose, brown, crisped. Stipe ± 

 40 c.M. long, rigid, polished, ebeneous like the rachis, the base densely mu- 

 ricate, the upper part rarely so, the prickles conical, recurved. Fronds ± 

 160 c.M. long, 3-pinnate. Pinnae spreading, the lower ones + 60 c.M. long, 

 divided as in D. flaccida, Bernh. The lower lobes with the margin often 

 undivided. Texture coriaceous ; upper surface dark-green, the under one paler.
