 fuse neur the base of the sporeling. Frequently five or 

 six lateral "branches are civen off from ea,ch of the lov/er 

 cells, so that the youn^^ ;^lant is copiously branched. In 

 this event, the cells bearing numerous branches becomes 

 thick-v/alled and almost globose in shape. 



It is interesting to note that \/hen niuabers of spore - 

 lings ai-e found in iioinediate vicinity in natu-re, all are 

 often at fefe© precisely the same sta-ge of development. "For

It is of considerable interest that the coenocytic
