. Found by Mr. Borrer in Sussex.
“ Distinguished from C. Hedwigii principally hy its more
flexible stems and more oblong nucules. When dry, it is
scarcely at all brittle, whereas C. Hedxoigii is extremely so,
Avhence it is called C. fragilis by some authors.”
Perhaps merely a variety of C. Hedxoigii.
4. Chara aspera.
Char. Stem very slender, scarcely brittle, obscurely striated
beset xoith scattered, spreadixig, or dejlexedbristles. Branches
o f the xohorls subulate ; the fex'tile ones with many whorls
o f shoj-t raxnidi or bractece, the two innermost longer than
the rest, bearing the globules or nucules which are
generally separate.

“ Found in hog pits, and still waters in several places in
the north of England and Scotland. Stem one or two feet
long, densely crowded, every Avhere beset with acute, slender,
straight, spreading or deflexed bristles ; and having at the base
of each whorl a row of appressed bristles, connected in pairs,
of which one points upwards and the other downwards.
“ Between the outer circle of tubes and central one,
in both the stems and branches, is found a green parenchyma,
arranged in lines alternating with the striæ, and separated or
broken transversely at intervals, giving them a spotted appearance;
globules and nucules solitary, often on separate
plants.
“ I have had this species under cultivation in a glass ja r for
several years, and although no nucules appeared at any time
upon it, young plants were copiously produced every spring.”

5. Chara hisriha.
Char. Stem more or less thickly covered with a calcareous
crust, opaque, brittle, striated, spinulose, or hispid.
Branches o f the whorls subulate ; the fertile ones xoith many
xohorls o f short ramuli or bractece, o f xohich three or fo u r
are larger than the nucule and globule that they accompany.

“ Not uncommon in ditches, lakes, and turfy bog pools.
The stony incrustation is sometimes so thick as to give the
plant the appearance of a petrifaction, which in other habitats
is nearly wanting. Almost as foetid as C. vulgaris. I t is
by far the largest of the true Charce in this country in its
ordinary form; and, though varying In the thickness of its
stem and branches, can never be confounded with the slender
and more delicate C. aspera.
“ A smaller variety is occasionally met with in which the
spinules arc obsolete, or nearly s o : the C. hispida ¡2' of
Agardh and Smith, /3 gracilis of Hooker, Eng. Bot.”
6. Chara latipolia.
“ This fine species, which I have no hesitation in stating to
be new to Britain, occurred in great abundance in Belviderc
Lake, county Westmeath, where I collected it in August last.
The great size and semipellucid appearance at once struck
me as remarkable. The main branches are striated and
covered with raised rough points, as are the first joints of the
whorled ramuli, while the remaining portion consists only of
one pellucid tube, which Is thicker than the lower joints, and
ends in a sharp point. The branches of the Avhorls are again
beset with smaller ramuli (not bracte®), in which respect it
differs from all our species in the opaque division. 1 regret
I could not find the species in fruit, neither globule nor
