 neater, rounded, very finely cut leaves, ij, floating in a strong 

 or rapid stream, has all its leaves dissected and lengthened out

 Hooker that the hairiness of the needs is no constant mark 3 for 

 after having long ago thought it such, I liave been obliged to 

 give up that point. See Rees's Cyclopcedia. I cannot but won-

 produced under their eyes, with the evident cause of each con- 

 tinually acting, can consider them as species.
