The species is H. Courbnril, Locust Tree. 



It is a large spreading tree in its native situa- 

 tion : it has a large stem, covered with a russet 

 bark, which divides into many spreading 

 branches, garnished with smooth stiff leaves, 

 which stand by pairs, their base joining at the 



partition : the seeds numerous, unequal (irre- 

 gular). 



The species cultivated are : 1 . H. niger. Black, 

 or Common Henbane; 2. H.retkulatus, Egyp- 

 tian Henbane; 3. H. all'us, White Henbane; 

 H. aureus, Golden-flowered, or Shrubby
