Rhizome firm, woody, short-creeping, the scales brown, lanceolate. Sti- 

 pes approximate, 7 — 15 c.M. long, erect, slightly scaly like the rachis, the 

 scales linear. Barren fronds simply pinnate, ovate-lanceolate, sometimes root- 

 ing at the apex, 15 — 50 c.M. long, 6—20 c.M. broad. Pinnae short-stalked, 

 + approximate, '/a — ^ c.M. broad, the sides parallel, the apex blunt, the edges 

 varying from slightly crenate to cut Vs'^^Y down to the midrib into oblong, 

 blunt lobes, with a seta or bristle-like tooth in the sinuses, the base unequal- 

 sided, the upper base subtruncate, auricled, the lower truncate or cuneate. 

 Texture herbaceous, firm; surfaces naked; veins visible, pinnate. Fertile 

 fronds on the longest stipes, pinnate; pinnae oblong or linear-oblong, much 

 shorter and narrower than the barren ones. 



W^ar. Hamiltoniana: Fertile pinnae contracted. Sori in bead- 

 like clusters without any connecting leafy membrane.

Rhizome erect, scaly at the extremity, the scales yellowish-brown, spread- 

 ing, lanceolate. Stipes 5 — 40 c.M. long, clothed towards the base with many 

 scattered, spreading or deflexed, lanceolate-acuminate, brownish scales, the 

 rest glossy, minutely pubescent or short-fibrillose and blackish-purplish, as 

 is the rachis. Fronds lanceolate-oblong, acuminate, 10 — 30 c.M. long, 7 — 15 

 c.M. broad near the base, the apex pinnatifid, the rest pinnate. Pinnae linear- 

 oblong, acuminate, pinnatifid, to 2^2 c.M. broad, broadest in the upper half, 

 slightly narrowed towards the base, the lowest a little abbreviate and deflexed. 

 Lobes oblong, erecto-patent, rather close, rounded at the apex, the longest 

 6 — 10 m.M. long, 3 — 5 m.M. broad, the lowest spreading and not rarely a 

 little elongated. Texture firm-herbaceous; surfaces naked; costae fibrillose
