Islands, Him.alayas (up to 4,000 ft.), Neilgherries, Ceylon, Mascaren Isles, Zambesi-land,
Angola, Guinea Coast.—This includes all the Eusagcnicc (six species) of Moore’s Index.
Tbe extremes differ in size very much, but all tbe forms appear to agree in sori and
venation.

ft. 1., with a large terminal pin n a cut down nearly to the rachis in the lower
p a rt into lanceolate divisions, with deep lanceolate-acuminate lobes, below this
several pinnæ on each side, the lowest deltoid, 1 ft. or more 1., by nearly as broad,
deeply pinnatifid above, pinnate below ; texture papyraceo-herbaceous ; main
veins distinct to the edge, with copious free included vemlets ; sori rather large,
in two rows, nearly all terminating free vemlets.
Hab. Burmab, Griffith.—This comes nearest the largest forms of the preceding, but
tbe venation is closer, and it has copious free veins, and sori not on the connected veinlets.
223. N. (Sagen.) giganteum. Baker ; st. 1-2 ft. 1., glossy, chesnut-brown ; f r .
2-3 ft. 1., 12-18 in. br., deeply pinnatifid a t tlie apex, with lanceolate sinuated
lobes ; below this 4-6 pinuæ on each side, the lowest much tlie largest, often
1 ft. 1., pinnate at the base, witli deeply pinnatifid pinnl. ; t e t e r e papyraceo-
herbaceous ; raehis and both surfaces naked ; veins anastomosing principally in
costal ai'clies ; sori large, terminating free veins, principally in rows on the lobes
on both sides the main veins.—Aspid. Blume. H k . Sp. 4. p. 50.
Hab. Ceylon, Philippines, Malaya.—Eesemblea A. cicutarium in babit, but the texture

scaly below ; f r . 2-3 ft. 1., 1 ft. or move br., with a large terminal pinna, often

1-3 in. br., entire or slightly lobed, the lowest pair forked at the base ; texture
papyraceo-herbaceous ; rachis and both surfaces usua lly naked ; prima ry veins
continued nearly to the edge, with numerous fine areolæ with free included
veinlets between them ; sori in 2 rows between each prima ry vein.—Aspid.

Sori round, arising from th e apex of the upper branch of a vein, generally
near the edge. Invol. reniform or roundish. Veins in all free, the fro n d s simply
pinnate, with the pinnæ articulated at the base and often very deciduous in the dried
plant, with white cretaceous dots on the upper surface. Belts the world in the
Tropics, passing a little beyond them both nm-th and south. T a b . V. f. 46.
