nartcd oblong, terminating the branches of the horizontal ramuli. Colmr
a brilliant crimson, given out in fresh water. Substance gelatinous,
frond adhering closely to paper in drying.
One of the rarest of the British Algte, scarcely known except
on the southern shores of England, and there only m a few
stations, and nowhere in great abundance. Perhaps one cause ot
Its comparative ranty is its place of growth. Being a Jep-water
species it is rarely found except when cast ashore after a gale,
or when sought by dredging. In the former case the specimens
are frequently very flaccid, and faded in colour. I am not
aware of its liaving been found in Ireland except, many years
ago, by Miss Ilutcliins.
There is considerable difference in structure and also m
appearance between young and old plants. In the former the
axis is a simple, jointed filament, not very tiiat of a
Grifdhsia, wlioried at short intervals with beaded fibres. But
as the plant increases in age, the axis becomes more compound
until it consists of a bundle of closely packed filaments; and
then the branches become thicker and more cylindrical. Favel-
m a are commonly produced in abundance. TeiroMpores are
much more rare.
