C ladophora latevirens; 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 th e branches six times, of th e ramuli

F requent on most of our rooky shores.
G eogr. D is t r . Atlantic shores of Europe and North America.
D e sor. 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 ou
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, fuU 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 di-ying.
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 resembling
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
