Annual. July. 



Root spindle-shaped. Stem bushy. Leaves sessile, soft and pliant, 

 sharply lobed, downy and viscid, exhaling a powerful and op- 

 pressive odour, like all the rest of the plant. Fl. numerous from 

 the bosoms of the crowded upper leaves, almost entirely sessile, 

 of an elegant straw-colour, pencilled with dark-purple veins. A 

 variety without these veins, mentioned by several writers, was 

 found at Fincham in Norfolk, by the Rev, R. Forby, with an in- 

 termediate kind, very faintly veiny. The capsules and seeds of 

 Henbane, smoked like tobacco, are a rustic remedy for the tooth- 

 ache j but convulsions and temporary insanity are said to be 

 sometimes the consequences of their use. The seeds, abounding 

 with oil, may safely be eaten raw, at least in small quantities ; 

 and an extract of the herb, very cautiously administered, is re- 

 commended by some physicians as an opiate.
