THE flower is extreamly minute. It confifts only of a cup formed of two Httle leaves; and 
is fucceeded by a finglf, oval feed, contained in a thin cruft, mimicking a capfule or fccd- 
veffel. The growth of the plant refembles the horfetail, jointed and furrounded at the joints with 
kaves. 
1 , Grey, brittle Char.i. 
Chara cinerea fragilis. 
The root is fibrous. 
The ftalks arc numerous, and three inches 
high. 
The leaves are llender, and furround them at 
the joints, which are placed very clofe on the 
upper part of the fl:alk. 
The flowers are inconfiderable. 
The whole plant is of a greyifh colour, and 
brittle. 
It is common on bogs, and fomctimes in ponds. 
Ray calls it Chara major Jukinerea fragilis. 
W'e have four other fpecies. 
i. Stinking, hntthCha.v!i, Chara vulgaris ftctida. 
Common under water in ditches. 
2. FncUyChm, Charamajor cauliiusfpino/is. In

4. Pellucid tough Chara, Chara Iranjlucins minor 
fexilis. Of a greenilh colour, and not brittle. 
To thefe, which, as they have no known vir- 
tues, demand in this work no larger notice ; yet 
with which, as they are Englifh vegetables, we 
would not leave the reader wholly unacquainted, 
we Qiall add a ftiort notice of the mofles, muih- 
rooms, and fubmarine plants. Thefe are fubjefts 
which might alone fill volumes of curiofity. We 
Ihall not extend this work beyond its deftined 
limits by a large account of them ; but in a few 
words, with the afliftance of their figures, give 
a general idea of their fcveral forms.
