Cladophoia cxispata. (Roth.) Kutz. Tab iv., t. 40, /. 1. 



Less coloured than the preceding, now and then dark green, 

 sometimes colourless ; branches and branchlets remote, some- 

 times secund, insertion (at least of the lower branches) apical, 

 articulations collapsing, cell contents (at least of the upper 

 branches) disposed in a lax spiral. Cell-uienibrane delicately 

 plicate-striate. 



SIZE. Primary branches -022 mm. thick, ultimate branches 

 less than half that diameter, main thread '12 mm. diam.

In pools. 



" Filaments about a foot long, or more, densely entangled, rather 

 tough, destitute of gloss, curled and crisped, especially when old. 

 Articulations 4 or 5 times as long as broad ; by drying they become 

 elliptical and compressed alternately."

Cladophora glomerata. (Linn.) Kutz. Tab. Phyc. iv. 



Branches in the upper part of the primary thread, and 

 branchlets of the second and third order, usually fasciculate or 

 penicellate. The cell contents of the larger cells applied in a 

 net-like or somewhat spiral manner to the walls. Fructiferous 

 cells always terminal, with the lower cells sterile. 



SIZE. Primary and secondary branches to *06 mm. diam. 

 3 to 6 times as long.

In clear streams and rivulets, usually attached to stones. 



"The whole plant is of a bright, shining green, very smooth, but not at 

 all viscid or gelatinous to the touch. The principal stems are several 

 inches long, sending out numerous capillary branches, which are variously 

 subdivided, and terminate ultimately in ranges of little short ramuli all
