This is a beautiful herbaceous plant, native of rocks in 

 Dalmatia, where we believe it was first discovered by General 

 Baron v. Welden. 



It is apparently a genuine Echium, having an irregular 

 corolla, with an erect limb, and perfectly even throat, without 

 any appendages. Nevertheless Reichenbach, in his Flora 

 excursorla, not only refers it to Lithospermum, but regards 

 it as a synonym of his L. rosmarinifolium^ which although 

 apparently not the true plant of that name is still a genuine 

 Lithospermum. 



The plant from which our drawing was taken, was raised in 

 the Garden of the Horticultural Society, from seeds presented 

 by Baron Welden, and flowered beautifully in a cool green- 

 house in May. At that time it was the gayest little plant 

 possible, with its neat clean leaves, stiff' stems, about nine 

 inches high, and pale blue flowers, which are pink before 

 they open. 



Fig. 1 . represents a corolla cut open ; 2. shews the ovary, 

 style and stigma. 



A pretty little hardy, evergreen shrub, growing from one

 loam and rough peat, that is rather poor. It must be kept
