Mr. C. C. Babington on the British species of Chara. 89 
Stems slender, erect, flexible even when dry, smooth, not 
opake, densely crowded, slightly branched, pale green. Lower 
whorls rather distant, upper ones gradually closer, of 8—10 short 
branchlets each with six nodes and a whorl of five bracts at each 
node. Bracts usually as long as the internode. Nucules soli- 
tary with thirteen striz and a prominent crown. My British 
specimens are of the male plant only. 
Wallroth refers Pluknet’s Irish plant to this with certainty ; I 
have doubts.

b. Stem coated with twice as many tubes as there are branchlets in 
each whorl. Branchlets coated, uppermost joints sometimes naked. 
12. C. vulgaris (Linn. ?) ; moncecious, stems scabrous finely stri- 
ated brittle, upper part of the branchlets without external 
tubes, bracts only on the inner side of the branchlets long : 
two 2—4 times as long as the nucules, and two equaling them.

Plant diffuse, almost always incrusted. Branchlets appearing, 
at the first view, joimtless, minutely pointed. Nucules with 
thirteen striz and a short crown, accompanied by the globule. 
Bracts thick. 
Varying greatly in appearance, size and roughness, sometimes 
hispid, sometimes much denuded of the outer tubes in the upper 
part. A very much condensed form is the C. montana (Schultz), 
Reich. Fl. exsic. 2143. The Linnean C. vulgaris appears to 
include this and several other species.

Annual. June to August. 
13. C. hispida (Linn.); moncecious, stem thickened upwards 
spirally sulcate rough brittle beset with setaceous spines, 
branchlets elongated, bracts whorled (inner ones much longer), 
nucules ovate shorter than the bracts solitary, accompanied by 
a globule.
