CLADOPHORA LATEVIRENS, Kitz. 
Gen. Cuar. Fidaments green, jointed, attached, uniform, branched. Fruit 
aggregated granules or zoospores, contained in the joints, having, at 
some period, a proper ciliary motion. Ciapornora (Aé/z.),—from 
kdados, a branch, and opew, to bear. 
Orapopnora /efevirens ; filaments much branched, bushy, forming tufts of 
a transparent, yellow-green colour, faded, and without gloss when dry; 
branches erecto-patent, crowded, repeatedly divided, flexuous, the 
lesser divisions often opposite ; ultimate ramuli secund, blunt, of few 
articulations ; articulations of the branches six times, of the ramuli 
thrice, as long as broad.

Has. On rocks, stones, and Algee, between tide marks. Annual. Summer. 
Frequent on most of our rocky shores. 
Geoer. Distr. Atlantic shores of Europe and North America. 
Descr. Root scutate. Filaments as thick as human hair, or somewhat more 
robust, 6-8 inches long, densely tufted, and very much branched; the 
main divisions somewhat zigzag, the lesser branches patent, spreading on 
all sides, unequal in length, set with two or more series of smaller branchlets, 
the last of which are frequently opposite. Ultimate ramuli one or two lines 
long, composed of three or four cells, somewhat curved, secund, obtuse, 
spreading. Articulations of the main divisions and larger branches several 
times longer than broad, of the ramuli about thrice as long, full of a bright 
endochrome, which is unequally dispersed when the plant is placed in fresh 
water. Colour a fine yellow-green, more or less discharged in drying. 
Substance membranaceous, soft, adhering, but not very firmly, to paper. 
A common species on most of our rocky shores, and widely 
dispersed through the northern Atlantic. Forms nearly resem- 
bling it, though they may appear under different specific names, 
are found in most parts of the world, within temperate latitudes. 
It was first proposed as a distinct species by Dillwyn, who draws 
attention to its peculiarly pale green colour and bushy mode of
