^B— 30 c.M. broad, ovate-lanceolate, with a loilgjfWminal,; pinnatifid/^ pinna. 

 Pinnae erecto-patent, alternate, ± ^%—5 c.M. apart, linear-lanceolate, 15—20 

 c.M. long, IS — 20 m.M. broad, the apex narrowed to an acute point, the 

 margin cut V3— Vs-way down into subacute (rather bluntish), slightly falcate 

 lobes, obscurely crenate at the apex. Texture papyraceous ; rachis dark-reddish- 

 brown, slightly canaliculate and hairy and scaly on the upper side, the scales 

 large, pale-brown; upper surface covered with pale or whitish hairs on the 

 costae and rarely on the costulae and veins; under surface finely glandular; 

 veins ± 8 — 10 on each side, only the 3 lowest ones anastomosing. Sori 

 costular, confined to the 4 — 5 lowest veins; indusium very fugacious.
