are said to arrive at a great size where these plants abound,<br />

feeding perhaps on their fruit and, more greedily, on the insects<br />

which they necessarily harbour.<br />

1. Chara. Vaill.<br />

(Character t/ie same as that of the Order.)—Name; its<br />

origin unknown.<br />

* More or less pellucid and flexible, not striated. (Nitella. Ag.)<br />

1. C. translucens, Pers. (translucent Chara) ; elongated<br />

smooth flaccid glossy and pellucid, branches of the whorls elon-<br />

gated patent obtuse simple with a short point, nucules and<br />

globules upon the smaller ramuli scarcely bracteated. Pers.<br />

Syn.Pl. v. 2. p. 531. E. Bot. t. 1703. E. FL v. 1. p. 8.—<br />

Nitella translucens, Ag. Syst. Alg.p. 124.<br />

Deep stagnant pools near Shrewsbury; Browston, Suffolk; Bagnley<br />

moor, Cheshire, Mr. Wilson. Several places in Scotland.— This is<br />

the largest the brightest coloured and most glossy of any of our<br />

species. Vaillant and Sir Jas. E. Smith describe the branches as jointed;<br />

but this appearance is, I think, wholly owing to a fold in the membrane<br />

of the tube, which is sometimes transverse and sometimes oblique.<br />

2. C. flexilis, Linn, (flaccid Chara) ; smooth flaccid somewhat<br />

glossy and pellucid much and frequently dichotomous,<br />

branches of the whorls simple or divided obtuse, nucules few,<br />

scarcely bracteated E. Bot. t. 1070. E. Fl. v. 1. p. 7.—<br />

Nitella flexilis, and opaca, Ag. Syst. Alg. p. 124.<br />

Ditches, lakes, and still waters, frequent.— Professor Agardh's Xittllu<br />

opaca, according to specimens I have received from him, only differs<br />

from the truvflr.ritis in having a partial incrustation and hence being more<br />

opaque. Mr. W. H. Harvey finds a variety in the lake of Killarney near<br />

Mucrnss, with the branches of the whorls more elongated than UsuUi,<br />

and fertile ramuli nestled among them. Mr. Born r observes the nucules<br />

and globules to be intermixed and clustered<br />

3. C. nidifica^ (Kd. (clash red Chara) ; smooth flaccid BOHM<br />

what glossy ami pellucid simple below, primary whorled branches<br />

limple elongated, fertile ones very numerous crowded and pro-<br />

liferous, nucules separated from the globules on the same plant<br />
