Hab. Cape Colony, northward to Angola, Zambesi Land, Bourbon, Mauritius, and
Madagascar.—Very near A. ohimatum, of which it may be an African form. Schlech-
tendahl referred it to Forster’s lucidum. The pinnæ vary considerably in textnre, and
here also there is a divided form {A. Jlexuosum, Schrad.) which has the pinnæ cut down
into narrow lobes about halfway down to the rachis in the upper part, and sometimes
quite down to it near the base.
S**. Group o f A . falcatum. Sori and veins long, irregular, subflabellate, very
oblique. Sp. 1)0-98.

which are 2-3 in. 1., J - | in. br., the point acute or bluntish, the edge sharply
toothed or often lobed, especially on the upper side towards the base, whicli,
if not lobed, is distinctly auricled and narrowed suddenly, whilst tlie lower
edge a t the base is obliquely truncate ; texture coriaceous ; raehis firm, erect,
grey, naked ; veins close, oblique, inconspicuous ; sori in 2 broad rather oblique
rovvs.—¡3, A . macilentum, Kze. ; rachis broadly winged ; pinnce b lu n t.—y, A . rigidum,

Hab. Polynesian and Malayan Islands, Australia, Hindostán, Johanna Island, Angola.
—Doubtfully distinct from A. falcatum. The best character is in the son, which are
more confined to the centre of the pinnæ, being often restricted to two parallel rows
close to the rachis.

veins very oblique ; sori in close long parallel lines reaching Irom tiie m iano
nearly to the edge.—-f/jí!. 8p, 3. p . 158. t. 196-7.
Hab. Polynesia, Malayan Peninsula and Islands, Hong-Kong, Hindostán, Ceylon
Mauritius, Johanna Island.-Very near the preceding ; indeed, all the species from 93
to 98 are very close to one another.
98. A. paradoxum, Blume ; st. firm, erect, grey,_ slightly scaly ; / r . 1-2 ft. L,

suddenly almost a t a right angle, the lower obliquely cuneate ; texture miia -

like ti.e stem, witli a laised line on each side ; no distmot imdr.h the vena ,on
