A verj' cm-ious genus, rare in the north-temperate zone, common in the south-temperate and tropics. The
species have erect, generally simple, sometimes dichotomously or flabellately branched, linear, flattened or filiform
fronds, wliich bear at tlieir apices a small, inclhied, pinnatifid limb or comb, upou whose divisions the capsules are
arranged.—Capsules in two series, close together ou each side of the costa of each division, partially covered by the
incurved margin, ovoid, sessile by the broad end, reticulated, striated at the smaller end, bursting laterally. Spores
with rounded angles.—The fructification deceptively appears borne on the upper siuface of the frond in this genus,
the upper portion of the latter being resupinate ; the gi'oove of the stipes, which indicates the true upper surface,
will be found on the opposite side from the capsules. (Name from (rx<£,<a, to divide; from the split fr'ond.)

The only Tasmaniau species of Todea is a tall, handsome, tufted Fera, with glabrous, bipinnate, coriaceous
fronds, the lower pinnæ on each division of which are generally densely covered with large, crowded, palc-brown
sporangia.—Pinmdes linear-oblong, serrate, blunt. Capsules large. (Named in honour of Henry Julius Tode, of
Mecklenburg, an eminent Mycologist.)

A very curious genus, found in almost all latitudes to whicli Ferus extend. Upwards of thirty species have
been made of it, many of which do not differ even as varieties from the common 0. vulgatum of Europe, and most
of them may, I think, be safely referred to that plant.-Foo/ of long fleshy fibres, sometimes descending from a
thickened base of the froud or tuberous rhizome. Frond simple, erect, 1 iuch to a foot long, bearing one (rarely
two) coriaceous, simple, linear or lanceolate or ovate, opaque or translucent leaf, with reticulate venation. Fructification
a long flattened spike, which is shorter or longer than the leaf, and consists of two opposite rows, each
of six to thirty globose capsules, cohering together and to a ceatral axis, each bursting transversely. Spores verj-
minute, rounded and trigonous. (Name from a serpent, and yXtucrtra, a tongue.)
