410 SYNGENESIA— POLYG.-SUPERF. Artemisia. 



Shjles very deeply cloven. Recept. convex, clothed with fine 

 upright hairs. 



Sometimes the leaves which accompany the flowers are much

Common Wormwood is a powerful bitter, much extolled by Haller, 

 on various authorities, as a stomachic, and recommended by 

 him for keeping off fits of the gout, for which it is said to have 

 served the Emperor Charles the Fifth. The plant is thought to 

 drive away insects from clothes and furniture, for which purpose 

 it is often laid into drawers and chests in the country. The ve-

 herb, and called Salt of Wormwood, though retaining none of 

 its peculiar qualities.
