The plant here figured is a very old inhabitant of 

 European Botanical Gardens, and, according to Dillenius, 

 was cultivated by Sherard, presumably at Eltham, in 

 1724. It was discovered by Rauwolf, during his travels in 

 the East in 1573-5, whose collections, now at Levden, 

 were published by Gronovius, under the title of " Flora 

 Orien talis," in 1755, p. 49. Rauwolf published an Itinerary 

 of his journey (which was translated into English by 

 Staphorst in 1693), also a work on medicinal plants in 

 1583. He was a native of Augsburg, and died Physician 

 of the Austrian Army in 1606. 



Rheum Ribes is a native of the lofty mountains of 

 Armenia, Kurdistan, Syria (the Lebanon), and Persia. 

 Boissier adds Beluchistan, but that is an error, R. spici- 

 forme, Royle, having been mistaken for it. "Rivas"is
