CHYLOCLADIA PARVULA, Zook. 
Grn. Cuan. Frond (at least the branches) tubular, constricted at regular 
intervals, and divided by internal diaphragms into joints, filled with 
a watery juice, and traversed by a few longitudinal filaments ; peri- 
phery composed of small, polygonal cells. Fructification of two kinds, 
on distinct individuals; 1, spherical, ovate, or conical capsules (cera- 
midia) containing a tuft of wedge-shaped spores on a central placenta ; 
2, tripartite ¢e¢raspores, immersed in the smaller branches, near their 
apices. CHYLOCLADIA (Grev.)— from xvdos, juice, and x«dados, a 
branch. 
Cuytoctapia parvula; frond subgelatinous, slender, bushy, irregularly 
branched; ramuli scattered; branches constricted at intervals of 
(nearly) equal length and breadth; ceramidia conical, with a promi- 
nent orifice.

Descr. Root composed of branched and matted fibres. Fronds three or four 
inches long, very densely crowded together, forming globular, intricate, 
bushy tufts, whose branches spread in all directions. Stem subsimple or 
irregularly forked, sometimes much divided, furnished with scattered, more 
or less crowded, alternate or opposite, occasionally whorled branches, as 
long as itself and very patent. Branches curved, more or less divided, and 
set with numerous scattered, patent or horizontal, obtuse ramuli, of nearly 
equal diameter with the parts they spring from. Articulations of the stem 
and main branches of uncertain length, and occasionally imperfectly defined ; 
those of the branches and ramuli pretty constantly as long as broad, or 
once and a half as long, contracted at the dissepiments. Ceramidia promi- 
nent, sessile on the branches, ovate or conical, with a prominent orifice, 
and containing a dense and very darkly coloured mass of tufted, obconical 
spores. Tetraspores minute, triparted, abundantly scattered through the 
lesser branches and ramuli. Colour, a pinky or dull red, changing in fresh
