Cladophoea R u d o lp liia n a ; filaments very long, exceedingly slender, flex-

ramuli pectinate, secund, very long and much a tten u a ted ; articulations
of th e main filaments many times longer th a n broad, here and
there swollen, their granular endochrome somewhat spiral ; those of
th e ramuli 6 - 1 0 times as long as broad.

G e o g k . D i s t e . Adriatic Sea, Agardh ! (v. in E e ri. Hook.)
D e s c e . Filaments exceedingly slender, forming very flaccid, subgelatinous
tufts from six to twenty inches in length, excessively branched, and in most
cases inextricably entangled. The branching appears to be an irregular
combination of dichotomous, and alternate, with here and there some opposite
branches ; and all the main divisions are either very flexuous or angularly
bent. The ultimate ramuli are very long, attenuated to a fine point,
aiid disposed in secund, subpectinate gi’oupst Frequently one of the joints
sAvells into an elliptical or spindle form, but without much apparent alteration
in its nature. All the joints are of gi'eat length, as compared with
their diameter, those of the main filaments being upwards of ten times
longer than broad ; those of the ramuli from six to ten times. Their endochrome
is lax, pellucid, and its granules are. attached in subspiral lines to
the waUs of the cells. The colour is a rich glossy gi-een ; the substance
very soft ; and the whole plant adheres closely to paper in drying, and preserves
its colour.
One of the commonest sea plants in Roundstone Bay, Cunnemara,
where it infects every oiiject on which it can lay hold, at a
depth of from two to six fathoms, or perhaps more. It is very
frequently found on the Laminaria, on Zostera, &c. Whilst
young, and freely waving in the water, it is a very beautiful
