 Rubus odoratus, L * 



North America. A kind of Easpberry. A handsome 

 species on account of its large purple flowers. Berry- 

 edible. Culture would doubtless enhance the value of the 

 fruits of many of these Eubi. Hybridising might be tried. 



Rubus strigosus, Michaux. 



North America. Closely allied to the European Easpberry. 

 Its fruits large, also of excellent taste. It would lead too 

 far to enumerate other kinds of Eubus, although about a 

 hundred genuine species occur, which render the genus one 

 of very wide dispersion over the globe. 



Eubus trivialis, Michaux.* 



Southern States of North America. Another shrubby 

 species with good edible fruits, which are large and black. 

 The plant will thrive in dry sandy soil. 



Rumex Acetosa, E. 



The Kitchen Sorrel. Europe, Middle and North Asia to 

 Japan, also in the frigid zone of North America. A peren- 

 nial herb. The tender varieties, particularly the Spanish 

 one, serve as pleasant aciduous vegetables, but must 

 be used in moderation, as their acidity like that of the speeies 

 of Oxalis (Wood-sorrel) depends on Binoxylate of potash. 



Rumex scutatus, E. 



The French Sorrel. Middle and South Europe, North 

 Africa, Orient. Also perennial, and superior to the fore- 

 going as a culinary plant. Both and the following are of 

 use against scurvy and most easily reared. 



Rumex vesicarius, E. 



South Europe, Middle Asia, North Africa. An annual berb 

 of similar utility as the two former ones. 



Ruta graveolens, E. 



The Eue. Mediterranean countries and the Orient. The 

 foliage of this acrid and odorous shrub, simply dried, con- 

 stitutes the Eue-herb of medicine. The allied R. silvestris, 

 Mill., is still more powerful in its effect. These plants and 

 others of the genus contain a peculiar volatile oil and a 

 Grlycosid (Eutin).
