Stipes short, to 5 c.M. long, approximate, slightly scaly, the scales fe

 25 — 55 c.M. long, 5—9 c.M. broad in the upper half, which is oblong-lanc(

 the apex; near the" middle the frond is rather suddenly narrowed into t 

 wing-like lower half, which is 1 — 2'/2 c.M. broad and decurrent upon t 

 stipe. Texture membranaceous to papyraceous; surfaces naked; cosla pror
