Aconites, The. By W. Irving (Garcl. p. 339; 14/11/03).— This 

 extensive genus is entirely confined to the northern hemisphere, the 

 species being chiefly European and Northern Asiatic, while a few are 

 found in North America. The nomenclature is in some confusion, owing 

 to the great number of names and various opinions of different authorities.

 flowering, from J uly into August, gives it additional value. Where the 

 area permits of its being boldly grouped it can be effectively planted, and

 while in its flowering season it is exceedingly handsome, each shoot being 

 terminated by an erect spike of flowers lasting from three to five weeks.
