Fronds forked. Branches oblong-lanceolate, 60 — 100 c.M. long, pinnate. 

 Pinnulae lanceolate, distant, alternate, the lowest stalked, 15 — 25 c.M. long, 

 cut down to a narrow wing into ± close, ligulate, spreading, blunt segments, 

 the higher ones growing gradually smaller. Texture coriaceous ; surfaces 

 naked, the under one green or glaucous; veins once forked. Sori medial,

Fronds large, forked. Branches to 6 M. or more long, bearing numerous 

 closely placed pinnulae. Pinnulae as long, 10 — 25 c.M. long, 2 — 5 c.M. broad, 

 cut down nearly or quite to the costa into numerous segments. Segments 

 linear-lanceolate or oblong, acute or rounded, pale or more or less glaucous

 rachises ± rough when they fall. Under surface densely tomentose with the 

 same scales. Capsules immersed between the tomentum.

Fronds forked. Branches flexuose, pinnate, bifurcate at the apex, ± 50 

 c.M. long. Pinnulae distant, alternate, spreading, dichotomously forked. The 

 1 — 3 lowest branchings nudate, the other ones leafy, with the rachises naked 

 or covered with deciduous, reddish tomentum. Ultimate branches 5 — 15 c.M. 

 long, 2 — 4 c.M. broad, acuminate. Lobes or leaflets spreading, 15 — 30 on
