as base, stout, 3—6” thick and occasionally muricate below, with a few 
broad ovate scales of 3—4, 12—20/ long, dark-green, purplish below; 
the rhachis compressed and margined in its upper portion. Frond dark- 
green, fleshy, glossy on the upper face, oblong, 18—24', pinnate with 
—16 pairs of pinnae, which are 1‘/2—2!/2‘ apart below and gradually 
decrease to a small terminal one. Pinnae on short stalks of 2—4”, the 
uppermost somewhat decurrent, lanceolate, 4—9/ >< 8/4—11/2‘, very acute, 
irregularly denticulate or crenate, abscisso-truncate at the base, with the 
upper half parallel to the rhachis and the upper angle acute or rounded. 
Veins sunk, indistinct, at angles of 30—40°, once or twice forked, ex- 
current in the margin. Sori linear along the trunk and anterior branch 
of the forks, straight, reaching from the midrib to the edge or falling 
little short of both, but often also on a posterior branch, then very close 
and the alternate ones shorter. Invol. pale and firm. — A. protensum,
