Frond chartaceous, oblong-lanceolate, 10—20‘ long, bipinnate except at 
the apex; the rhachis fibrillose, compressed and generally proliferous 
below the apex, as are also often the rhacheoles. Pinnae 10—16 on a 
side, patent, the lowest 3—5’ X 1—1'/2‘, pinnulate in the inner, pinnatifid 
in the outer half, the upper basal pinnule parallel to the main rhachis. 
Stipitate pinnules 3—5 on a side, ovate-rhomboidal or oblong, 8—10”

and both sides bluntly dentate .or serrate, the upper face striately im-

nerve or costule at angles of 10—30°. Sori 6 or 7 to a pinnule, reaching 
from costule to edge; in the pinnatifid portion of the pinnae and in the 
apical portion of the frond as in A. pseudofalcatum. — A. spathulinum,
