Rhizome creeping, the scales lanceolate, acute or acuminate. Stipes naked, 

 castaneous. Fronds 2-pinnate, + 15 c.M. long, branched in the lower half, 

 the lowest branches much the longest. Leaflets orbicular-cuneate, + 1 — 1 '/j 

 c.M. broad, the base cuneate, the upper and outer edge deeply crenate or 

 rather deeply lobed and crenate, the lobes cuneate-flabellate or cuneate-oblong. 

 Texture thin, membranaceous or more rigid; surfaces naked; veins flabellate. 

 Sori interrupted by the lobes and crenations ; indusium narrow.

Stipes 10 — 13 c.M. long, like the rachises slender, naked, castaneous. 

 Fronds deltoid, 2-pinnate. Branches few, 15 — 20 c.M. long, 8 — 9 m.M. broad. 

 Leaflets sessile, cuneate, 4 — 4*/2 m.M. broad, crenate on the outer edge. 

 Texture moderately firm; surfaces naked; veins + 3 to a pinnula, forked. 

 Sori roundish or oblong, terminal on the pinnulae; indusium narrow, firm.

Rhizome short-creeping, paleaceous. Stipes strong, erect, polished^ 20 — 60 

 c.M. long. Fronds 2-pinnate, 30—45 c.M. long, 20—30 c.M. broad, with a 

 long, terminal branch and 6 — 10 pairs of lateral ones, which are 15 — 25 c.M. 

 long. Leaflets 5 — 10 m.M. long, 3 — 5 m.M. broad, closely placed, often 

 slightly imbricate, the upper edge entire, the apex broadly rounded, entire 

 or finely toothed. Texture pellucido-herbaceous to subcoriaceous ; veins pro- 

 minent. Sori in a continuous, submarginal line.

Rhizome wide-creeping. Stipes 10 — 15 c.M. long, rigid, erect, prickly 

 towards the base. Fronds 2-pinnate, with a long terminal branch and 1 — 9 ; 

 pairs of remote, lateral ones 10 — 20 c.M. long. Leaflets 6 — 10 m.M. long, 

 4 — 5 m.M. broad, the lower edge often falcate, the upper 3 — 4 times bluntly, 

 not deeply lobed, placed close together, not imbricate. Texture very thick 

 and coriaceous; veins prominent. Sori sub terminal on the lobes. — The 

 colour of the nature frond is sepia-brown and the pale veins stand out from 

 the ground-work in relief (Bk). ,
