History, Use, Propagation, Culture, 
2302. Sphacellaria. This name has been suggested by the sphacelated appearance of the truncated extremities 
of the shoots, in which the reproductive organs are immersed. 
2303. Cladostephus. From xXoiho?, a branch, and 5"£i?fl?, a crown, in allusion to the manner in which the 
first stem is crowned as it were by the little compound whorled branches. 
2304. Vaucheria. So named, in honor of M. Vaucher, of Geneva, an indefatigable collector of submersed 
Algse. 
2305. Codium. From fiou^tov, a skin, with reference to the appearance of the second species. 
2306. Bryopsis. The filaments of this genus form little pinnated or imbricated branches, resembling bits of 
moss J whence the name has been formed, from /3§u«v, a moss, and e^}//^, resemblance.
