The second species has a perennial creeping root, sending up 

 several strong stalks two feet high, and branching. The leaves cut 

 into many fine segments to the mid rib. Each branch is terminated 

 by a globular head of flowers, smaller than those of the first, and of 

 a deeper blue, but sometimes white: they come out in July. It is a 

 native of the South of France. 



It also varies with white flowers. 



The. third is an annual plant, with a stiff while stalk two feet high. 

 The leaves divided, ending in many points, which have spines; their 

 upper side green, covered with brown hairs, their under side white 

 and woolly : the stalk is terminated by one large head of pale blue 

 flowers, appearing in July. It is a native of France, &c. 



Culture. These plants are readily increased by sowing the seeds 

 in the autumn in the places where the plants are to grow. When 

 they are come up in the spring, they should be properly thinned and

 sown in the early spring. 



They are well suited to afford variety in the large borders of gar- 

 dens or pleasure-grounds, as they succeed in almost any soil.
