CLADOPHOK A. 213 



Sub-fam. i. Cladophoreje. 



18. CLADOPHORA JiTw^^. 



Char. Filaments attached, much branched, not setigerous, 

 and not invested loith secondary cells. 

 Derivation. From Kkahos, a branch, and (popsco, to bear. 



This important genus I established in the " Annals of Nat. 

 Hist." vol. xi. p. 363., under the name of Microspora. Sub- 

 sequently finding the same genus to have been characterised 

 by Klitzing in his " Phycologia Generalis," I have been in- 

 duced to adopt his generic name, it appearing to be the more 

 appropriate. 



The genus should contain amongst the freshwater Confervas, 

 C. glomerata and C. crispata, and the majority of the marine 

 branched ConfervcE. Conf. cerea and its numerous allies 

 should form another genus, agreeing in its reproduction 

 closely with Cladophora, but differing from that genus in 

 the simplicity of its filaments : this genus might be deno- 

 minated Aplonema,* The filaments when dry are destitute 

 of gloss, like those of the Cystospermece, and do not adhere 

 well to paper.

 shining. Branches crowded, irregular, erect ; the ultimate 

 ramuli secund, subfasciculate. Articulations jfoz^r to eight 

 times longer than broad.
