Grows naturally in shady places in Italy and the Levant. 

 Found also by Monsieur Destbntaines in Barbary, where it 

 grew in the rocky fissures of Mount Atlas. Cultivated in 

 our gardens in 1640. 



A biennial plant ; seldom exceeding two feet and a half in 

 height ; flowers either blue or white, upright, small, produced 

 in close numerous-flowered somewhat convex cymes at the 

 end of the branches, which are placed at the upper part of 

 the stem; leaves loosely alternate, ovate, acuminate, une- 

 qually serrate, smooth as well as the rest of the plant. In 

 bloom from July to September. Both scientific and ver- 

 nacular appellations have been suggested, by the long tube 

 or neck of the corolla.
