PENTANDRIA— MONOGYNIA. Echium. 267 



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, notwithstandhig the above eminent au- 

 thority.
