CLADOPHORA. 213 



Sub-fam. i. Clabophoreje. 



18. CLADOPHORA Kutz. 



Char. Filaments attached, much branched, not sctigerous, 

 and not invested zcith secondary cells. 



Derivation. From kKoBos, a branch, and ^opsw, to bear. 



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

 Hist." vol. xi. p. 363., under the name of 3Iicros]wra. Sub- 

 sequently finding the same genus to have been characterised 

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

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

 approiDriate. 



The genus should contain amongst the freshwater Conferva 

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

 branched ConfervcB. Conf. area and its numerous allies 

 should form another genus, agreeing in its reproduction 

 closely with Cladoj^hora, 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 Cystospermeoe, and do not adhere 

 well to paper.
