Rhizome creeping, nearly woody, brownish, bearing the fronds at the 

 extremity. Stipes 10 — 30 c.M. long, hairy above. Fronds \^^\^—Z0 c.M. 

 long, pinnatifid in the upper, pinnate in the lower half. Terminal pinna to 

 15 c.M. long, to 2^2 c.M. broad, narrowed gradually from the base towards 

 the acuminate point, the edge deeply pinnatifid. Lateral pinnae 4 — 5 or more 

 on each side, sessile, spreading or erecto-patent, + oblong, the largest ± 4 

 c.M. long, + 1 — 2 c.M. broad, the lowest deflexed, sometimes reduced, (he 

 edge not deeply lobed. Texture firm, upper surface deep-green, lower + 

 greyish-green; both surfaces ± hairy on the veins. Fertile fronds often 

 with the narrowest pinnae. Sori small, oblong or sometimes roundish, + 

 medial on the veins. 



Var. lobata: Pinnae less numerous, broader, the lobes broader, 

 less numerous, deeper; veins flexuose, sometimes irregular; areolae in 1 row 

 on each side. Sori often irregularly elongated. Pubescence grey. 



Var. deffener: Rhizome nearly creeping. Fronds ± 20 — 40 c.M. 

 long; texture firmer; colour rather blackish-green. Pinnae ovate, often obo- 

 vate, narrowed at the base, obtusely crenato-lobate, the terminal one elongate, 

 broad, obtusely lobed; barren pinnae short (+ 6 m.M. long), fertile ones 

 often longer (to 2*/^ c.M. long), stalked, distant. Sori irregularly scattered, +
