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 Ecbium, having an irregular 
corolla, with an erect limb, and perfectly even throat, without 
any appendages. Nevertheless Reichenbach, in his Flora 
excur soria , 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 
to two feet high. It succeeds best in a mixture of sandy 
loam and rough peat, that is rather poor. It must be kept
