acuminate, the base cut in the lower i subtruneate with rounded angle 
in the upper half, the edge subentire or sharply cut at angles of 5—50° 
into 5— 
Ber being oblong and sharply serrulate at the rounded apex, the 
uricular one often cut to near the rhachis and obovate-oblong, with 
Prin flabellate veinlets. Veins very close. Primary sori through the 
entire lengt the pinnae, ssh NE and contiguous to the costa in 
the outer ee deflecti ra angles of 10—20° but always short of the 
edge in the inner half, 2—6” long; bay hss sori radiating in the inner 
half of the staiitts siieis and in the larger segments of the incised 
forms, all falling short of the edge. Invol. rather firm, obtuse at both 
ends 
olokai! W. Maui! woods of Hilo, Hawaii! Rare. — The Hawaiian representative 
of A. fale i Lam., t e form of which em ti in 
up. At the pinnatifid apex of the frond the sori are crowded close to the rhachis as in t 
pinnae of ontiguum. ae of the lier incised forms can hardly be tin 
guished from a pinnule of a moderately incised A. patens, unless by the firmer texture. 
22. A. caudatum, Forst. — Hook. Sp. Fil. IIT, 152. — Rhizome creeping, 
stout, 1/2—%/4’ thick, densely clothed with dark-brown linear-lanceolate 
scales of 3—5” sete run out into a long, not capillary, acumination. Stip. 
about 6” apart, stout, 8—14’ long, 11/2—3” thick, dark-brown, sparingly 
fibrillose or naked. aie nd chartaceous, chive Jaemesi when thin, of a deeper 
color when thicker, with satiny lustre on both sides, oblong, nar- 
rowing below, 1—3 ft. long, pinnate, with pinnatifid apex. Pinnae 20—40 
on a side, shortly stipitate, oblong-lanceolate, 2—5‘/  1/2—1', the larger 
ones gradually enlarging toward the little dilated base, which is abscisso- 
truncate with the upper half receding from the rhachis and rounded off, 
acute or caudate-acuminate, subentire, or serrate-incised, sometimes deeply 
near the base, by narrow slits at angles of 20—50° into oblong and ob- 
liquely truncate to rounded lobes. Veins semitransparent with isha 
light, repeatedly and closely forking, except near the apex. Primary s° 
4—10” long on the anterior branches at angles of 10—20°, imbricate a 
close to the costa, slightly curved, all short of the space in the simple 
pinnae these only, in the deeper lobed ones also a few secondary sori 
irregularly Aegon on the disks of the lobes, but never Pacing the 
margin. Invol. thin, narrow, Sati at both ends. — Synops. Fil. p. 209.
