about 6‘, their rhachis compressed in the upper half. Pinnules, 7 or 8 
on a fie besides a terminal one, at angles of 40—45°, the inferior basal 
one opposite the second upper, narrow- lanceolate, nits acuminate, entire 
or sanay denticulate, the cuneate base running i ort margined 
stipes; the first inner pinnules 21/2‘ 3”. Veins Inset, pinnate at 
angles of about 20°, simple or once forking. Sori 12—26 on a pinnule, 
extending from near the costule to the margin, 1aeét firm, pale. —

ahu! Nin. — A large and handsome fern, evidently connected with A. Kaulfussii. 
The change é was uncalled for, th bipinnatum of Bracken

author, of 4. dichotomum, Hook., and of other names, mM are all united under the

13. A. Lydgatei, sp. n. — Stipes 7—18’ long, scaly at the base. Frond 
ovate, 7—10‘ long, obtuse, chartaceous, pale, bipinnate, with 8—10 pinnae 
on each side, which decrease abruptly, the terminal pinna pinnatifid. 
Rhachis flat and margined in the upper half. Pinnae patent on stipites 
2—3, ovate in outline, the middle ones longest, 3'/2—4*/2’ long, with 
pinnatifid apex, the superior basal pinnule shorter than the two next 
following, the inferior basal one at half the distance between the two 
first upper ones; their rhachis flat and slightly margined. Pinnules 5 or 
6 to a pinna at angles of 35°, rhomboidal or lanceolate, 11/2—2!'/4’ K 4—6", 
long-acuminate, the cuneate base running into a margined stipes, the 
edges crenate-serrate to deeply incised with subfalcate or cuneate-oblong, 
simple or bidentate lobes. Veins distinct, pinnate at angles of about 20°, 
simple or forking at the middle. Sori broad, on the anterior branches 
of the forking veins, 2—4” long, rather distant from each other, in two 
parallel rows, but marginal, ae in deeply incised pinnules. Invol. 
firm middle pinnae are lar and their pinnules more deeply 
cut than those of the lower ones. pe 11/2, dark and stiff, the dividing 
walls of the short hexagonal cells as thick as the opening.

14. A. meiotomum, sp. n.— Caudex short and prostrate, 1‘ thick, the 
rootlets covered with a rufous fur. Stipes crowded, slender, with a few 
black lanceolate long-acuminate pees re scales at the base, green, 6—8* 
long, flat in front. Frond ovate- -oblong, 9—12' X 5—6‘, obtuse, thin 
chartaceous, bipinnate, tripinnatisect, with about 12 pinnae on either 
side, which Ween abruptly at the apex. Rhachis not margined. Pinnae 
erecto-patent, on petioles of 2, subopposite, oblong, the middie ones 
31/2—4‘ long, the lowest pair a little abies, with pinnules less deeply 
‘cut. Pinnules 6 or 7 on either side at angles of 40°, alternate, narrow.
