Fish-ponds in Jersey, Sherard. Boggy pools in St. Leonard's forest,
Sussex, Mr. Borrer. Llyn Idwel, N. Wales, Mr. W. Wilson.—My
specimens of this from Mr. Borrer, corresponding with those figured in
E. Bot., do appear, at first sight, distinct from C. flexilis. They are
small, delicate, pale coloured and very glossy. But I have other individuals
from the same acute Botanist marked " C. gracilis as to ramification,
not as to size," which I cannot distinguish from C. flexilis. Mr.
Wilson's specimens are intermediate, but more allied to the E. Bot.
figure. Sir J. E. Smith observes that the nucules and globules are
usually together : Mr. Wilson finds them always in Llyn ldwel on dif-
ferent plants.
** Opaque and very brittle, striated, often spirally. (Chara. Ay.)
5. C. vulgaris, Linn, (common Chara) ; smooth opaque
brittle (but not incrusted) very obscurely striated, branches of
the whorls slender subulate, fertile ones with many short ramuli
or bractese 3 or 4 of which are much longer than the globule

and nucule that they accompany.

Ditches and slow streams, frequent.
6. C. Hedivigii, Ag. (Hedwigian Chara) ; elongated smooth
opaque brittle (sometimes partially incrusted) obscurely striated,
branches of the whorls subulate, the fertile ones with
many short ramuli or bractese 3 or 4 of which are shorter than
the nucule and globule that they accompany. Ag. Syst. Alg.

Alg. p. 129.
Still pools ; Buxtead, Sussex, Mr. Borrer. Near Croft, Yorkshire,
Rev. J. Dalton.—Larger than the preceding, with more numerous fertile
branches and shorter bracteas. The branches are jointed in both at the
setting on of the ramuli or bracteas, which, being numerous, the joints
are consequently numerous.
7. C. dspera, Willd. (rough Chara) ; slender opaque brittle
obscurely striated every where beset with patent scattered
spinules, branches of the whorls subulate, the fertile ones with
many short ramuli or bractese of which 3 or 4 accompany the
nucule or globule (on different plants) uncertain in length.

Peat-pits in Cleiviog Farm, 4 miles from Holyhead, Mr. W. Wilson.—
In one of my specimens, from Montpellier, I find the globules on the
same plant with the nucules, but apart from them.
8. C. hispida, Linn, (hispid Chara); opaque brittle striated
covered more or less thickly by a calcareous crust, branches
