forming definite sori in the frond, or in distinct foliaceous leaflets.
Grev.
25. Nitophyllum. Frond plane, delicately membranaceous,
rose-coloured, reticulated, wholly without veins or only
with very slight vague ones towards the base. Fructification
hemispherical capsules, imbedded in the substance of the frond ;
and ternate granules, forming distinct scattered spots. Grev.
26. Rhodomenia. Frond plane, membranaceous, fine pink
or red, quite 4 veinless, sessile, or with a short stem which expands
immediately into the frond. Fructification ; hemispherical
scattered capsules; and minute ternate granules, spreading
over the whole or some part of the frond, (not in defined spots.)
Grev.
27. Plocamium. Frond filiform, compressed, between membranaceous
and cartilaginous, fine pink-red, much branched,
branches distichous (alternately secund and pectinate). Fructification
: spherical, sessile capsules; and lateral minute pro-
cesses, containing oblong granules, transversely divided into
several parts by pellucid lines. Grev.
28. Microcladia. Frond filiform, compressed, subcartilaginous,
irregularly branched, the branches distichous. Fructi-
fication ; sessile spherical capsules, accompanied by an involucre,
in the form of several short ramuli; and ternate granules, in the
swollen apices of the branches. Grev,
29. Odontiialia. Frond plane, between membranaceous
and cartilaginous, dark vinous-red, with an imperfect or obso-
lete midrib, and alternately toothed at the margin. Fructification
marginal, axillary or in the teeth : capsules containing
pear-shaped seeds, fixed by their base ; and slender processes
containing ternate granules. Grev.
30. Rhodomela. Frond cylindrical or compressed, filiform,
much branched, coriaceo-cartilaginoua (the apex sometimes involute).
Fructification} subglobose capsules, containing free
pear-shaped seeds ; and pod-like receptacles with imbedded ter-
nate granules. Gn r.

sules, containing a cluster of pyrifbrm (compound ? ) seeds, fixed
by their base. Gtk v.
