" Fronds several inches long, about the thickness of a bristle, smooth,
cylindrical, very much branched and interwoven into a thin inextricable
fleece, sometimes of great extent, branches exceedingly unequal, patent
or recurved. Substance membranous, latticed, of a green colour.
Agardh has made E. erecta a variety of this species. This is an easy
way of getting over the ground, to be sure, to huddle plants together as
mere varieties of each other; but the characteristics which distinguish
these Alga?, are too decided to admit of their approximation ; the one being
erect, with long, equal, loose and disentangled branches, the other pros-
trate, with branches of all lengths interwoven into a matted web. If
this difference of habit do not constitute a difference of species, where
are we to look for such ?" Carm* MSS.
7. E. ramidosa, (branchleited Enteromorpka) ; frond latticed
compressed twisted divaricatedly, very much branched and in-
terwoven, every where covered with spinulose branchlets.

" Fronds 5—G inches to 1 and 2 feet long, $ a line in diameter, com-
pressed, curled and twisted, much and repeatedly branched and interwoven
into a (more or less) thick and inextricable mat, and beset on
all sides with short Bpine-like branchlets, or rather apiculi, which render
it harsh to the touch, Substance membranous, green. This species
can be distinguished at once Brora E. clathrata, with which alone there
is any risk of its being confounded, by mere handling, the one feeling
harsh and rough to the touch, the other soft and silky." Carm. MSS.
— Notwithstanding the great Btress my late valued friend, Capt Carmichael,
lias laid upon the distinguishing characters of this and the two
preceding species, other able Botanists think differently of their importance]
and 1 must confess, that there are intermediate
these plants, which would rather lead me to coincide with Dr. GreviHe
and to unite them. In the ramification tiny are extremely variable, in
the clathrate or latticed structure of the frond [by which they are distinguished
from all others f the geQUS) very uniform and Constant
s. I-;..- percurta, (Cbf^ferm-Jft Bnteromorpha); frond very
ilender capillary oompreeaed marked with gporioua reticalaUous
and a central longitudinal line. Carm. M s s '• Soi < m)i
