Gen. Cuar. Filaments green, attached, uniform, branched, composed of a 
single series of cells or articulations. wif, aggregated granules or 
zoospores, contained in the articulations, having, at some period, a 
proper ciliary motion. CrapopHora (A‘tz.),—from kdados, a branch, 
and qopew, to bear. 
Crapornora fracta; tufts irregular, entangled, often detached and then 
forming floating strata, dull green; filaments somewhat rigid, dis- 
tantly branched, the lesser branches somewhat dichotomous, spreading, 
with very wide axils, the ramuli few, alternate or commonly secund ; 
articulations from three to six times as long as broad, at first eylin- 
drical, then elliptical, with contracted dissepiments.

Has. In ditches of brackish water, communicating with the tide ; also in 
fresh-water lakes, ditches, and streams. Common. 
Geroer. Distr. Abundant throughout Europe. 
Descr. At first forming loose tufts, which frequently become detached, and the 
plant is more commonly found constituting floating strata, many tufts en- 
tangled together in each floating mass. laments capillary, from six to 
eight or ten inches long, much, but very irregularly branched, the branches 
distant, spreading at wide angles, or much divaricated, either dichotomous 
or alternate ; the lesser branches repeatedly forked, with wide axils, and 
the ramuli, which are few and very patent, commonly secund, sometimes 
alternate. Articulations three or four times as long as broad, rarely six 
times as long, those of the upper branches pretty uniformly thrice as long 
as their diameter, at first cylindrical, then becoming pyriform, and when 
mature elliptical, when the branches resemble strings of dark-green beads. 
Dissepiments finally much contracted. Colour at first a pleasant grass- 
green, becoming darker and duller as the plant advances in age. The en~
