CHYLOCLADIA ARTICULATA, Grev.
G e n . Ch a r . Frond (at least the branches) tubular, constricted at regular
intervals, and divided by internal diaphragms into joints, fflled with
a watery juice, and traversed by a few longitudinal filaments; periphery
composed of smaU, polygonal cells. Fructification, of two
kinds, on distinct individuals; 1, spherical, ovate, or conical capsules
{ceramidia) containing a tuft of wedge-shaped spores on a central
placenta; 2 , tripartite teUaspores, i m m e r s e d i n the smaller branches,
near their apices.—Chylocladia {Grev.),— h om xvEos, ffiice, and
cXaSor, a branch.
C hylocladia articulata; frond tubular, gelatinoso-membranaceous, strongly
constricted throughout as if jointed, much branched, between pinnate
and dichotomous, fastigiate, the upper branches often crowded ; capsules
obtusely conioal.

G e o g r . D i s t r . Atlantic and Mediterranean shores of Europe.
D e s c r Boot of manv branching fibres matted together. Eronds densely tufted,
six or eight to ten inches or more in length, from a quarter line to a line
in diameter, tubular, filled with watery fluid and traversed by a few fibres
constricted throughout at regular intervals into joints, the lowermost of
which are cylindrical, the upper gradually more eUiptical, and those of the
upper branches frequently beaded;—much branched from the base, the
primary branching dichotomous, the secondary often opposite or somewhat
pinnated, and the ramuli frequently whoiied round the nodes, particularly in
the upper half of the p la n t;—thus old tufts often become very dense and
bushy above from the inordinate number of these whorled branches and
