Gen. Car. Filaments green, jomted, uniform, branched. Prait, aggre- 
gated granules or zoospores, contained in the joints, having, at some 
period, a proper ciliary motion. CxiapopHora (Avfz.),— from 
krados, a branch, and popew, to bear. 
CrapopHora glaucescens ; tufts dense, glaucous-green, subfastigiate ; fila- 
ments very slender, flexuous, excessively branched ; branches rather 
straight, erect, or erecto-patent, the lesser ones furnished with close, 
very “erect, straight, elongated ramuli; articulations nearly uniform, 
about thrice as long as broad. ;

Descr. Root, a small callus. Filaments very slender, densely tufted, two to 
four inches long, sometimes forming circumscribed tufts, sometimes more 
unequally distributed, excessively branched ; the principal branches v ariously 
curved or irregularly bent, the lesser ones more and more straight and erect, 
alternate, or secund, very rarely opposite, repeatedly divided. Ultimate 
ramuli usually elongated, consisting of several cells, secund, erect, close 
together. Articulations uniform in all parts of the frond, about thrice as 
long as broad, filled with a pale green, not very dense endochrome, which 
is more or less dissipated in drying. Sudstance membranaceous, rather 
soft, but not flaccid, adhering, but “hot very closely, to paper in drying. 
When dry, the colour is sometimes a pale green, sometimes darker; and 
the filaments preserve a slight gloss.

This is one of the many beautiful plants for whose correct 
determination the Phycologist is indebted to the accurate eye 
and discriminating judgment of Mrs. Griffiths, who first pub- 
lished it in Mrs. Wyatt's excellent Fasciculi of Devonshire Alge. 
It is difficult to say to which of the British species of Cladophora 
it is most closely allied. At one time I regarded it as belonging to 
the same group as C. arcta, and even thought that it might prove 
to be merely a state of that species: but a more careful examin-
