 CLADOPHORA BAINESII, F. Mmll. et Haw. 



Gen. Char. Filaments tufted, articulated, uniform, branched. Articula- 

 tions filled with green, granular endochrome, which is changed at 

 maturity into zoospores. — Cladophora [Kiitz.), from kXuBo^, a 

 branch, and (f)op€co, to hear. 



Mia ciBspitosa, articulata, ramom. ArticuU endocliromate viridl (/rtimoso, de- 

 mmn in zoospores mutato, repleti. 



Cladophora Bainesii ; yellow-green, glossy when dry, very soft, with a 

 long stipes ; filaments setaceous at base, then capillary and very much 

 attenuated upwards, elongate, di-trichotomously much branched ; 

 branches trichotomo-multifid, set with multifid lateral ramuli; ulti- 

 mate branchlets long and filiform, acute or mucronate ; articulations 

 of the branches very long, cylindrical, 20-30 times longer than 

 broad, constricted at the joints of the ramuli, 6-10 times as long as 

 broad.

Descr. Root a small disc. Filaments 6-10 inches long, tufted, the basal cell or 

 stipes rising without branch or dissepiment for 2-3 inches, then three-forked, 

 and afterwards repeatedly di-tricliotomous and multifid. The stipes is 

 nearly as thick as hog's-bristle, and somewliat rigid ; the branches into 

 which it first divides are capillary, growing more slender at every node, 

 and soon the filament becomes excessively slender, more frequently branched, 

 very soft, and the order of ramification not easily distinguishable. The 

 articulations throughout the filament are of great length, cyhndrical, filled 

 with endochrome; those of the lower forkings fihform, 40-50 times as 

 long as broad ; those of the upper gradually shorter, and towards the ends 

 of the branches 10-20 times : in the ramuli they are 8-10 times, slightly 

 constricted at the nodes, the terminal cell obtuse. The colour is a pale
