26S PENTANDRIA— MONOGYNIA. Echium. . 



Dr. Lehmann has reduced this genus to Anchusa, with 

 which it agrees in the bordered scar of the seed; but the 

 curvature of the tube affords a remarkable and constant 

 character, and I concur with Professor Hooker in keep- 

 ing them distinct, notwithstanding the above eminent 

 authority.
