CLADOPHORA REPENS, J. 4. 
Gen. Cuan. Hilaments green, jointed, uniform, branched. uct aggre- 
gated granules or zoospores, contained in the joints, having, at some 
period, a proper, ciliary motion. CxiaporHora (Kétz.),— from 
khados, a branch, and pepe, to bear. 
CiaporHora repens; forming dense, cushion-shaped or globular tufts ; 
filaments short, capillary, rigid, densely matted together, rising from 
root-like fibres; slightly branched; branches erect, subsimple, or 
forked, naked, or with a few distant, secund ramuli; articulations 
cylindrical, very long (ten to twenty times as long as their diameter).

Descr. Tufts very dense, an inch or two in breadth, and about half an inch in 
thickness, globose or oblong, cushion-like, composed of innumerable, capil- 
lary filaments, closely matted together. The filaments are at first decumbent, 
connected by root-like fibres, which form the substratum of the tufts ; 
from the decumbent filaments issue, at the joints, erect branches, half an 
inch in length, simple, or once forked, and either naked or furnished with 
a few simple, distant, secund ramuli. Each branch consists of about four 
or five, rarely more, articulations; and each ramulus usually of one, 
rarely of two articulations. The articulations are therefore of great 
length, as compared with their diameter; in our specimen the length is 
frequently as much as twenty times the breadth:—they are cylindrical, 
and the diameter at the tip of the branches is as great as at the base. 
The colour appears to have been a dark green; it is dingy and somewhat 
olive-green in the dried state. The substance is rigid, and the plant does 
not adhere to paper when dry. 
In a recent number I had the pleasure of figurmg a new 
species of Dasya from the shores of Jersey, and I have now to 
introduce, from the same locality, a Cladophora, discovered by 
my valued correspondent, Miss Turner, to whom I am indebted 
for many Jersey Algee. Miss Turner informs me that the speci- 
mens were picked up on the beach after a heavy gale, in 1846 ; 
four only were found, and the plant has not since been noticed.
