XVII. ARGY'LIA (this beautiful genus is dedicated to the 

 memory of Archibald, Duke of Argyle, a nobleman distinguished 

 for his patriotic virtues, and love of science, and more especially 

 of botany. His fine garden at Whitton Park, in Middlesex, 

 was justly celebrated towards the middle of the last century. 

 It contained a very extensive collection of plants, particularly 

 of ornamental and useful American trees, many of which he him- 

 self first introduced to this country.) D. Don, in edinb. phil.

Ray-\ea.ved Argylia. PI. 1 foot. 



Cull. The species of Argylia are extremely splendid while 

 in blossom. They will thrive best in a light rich soil, such as a 

 mixture of loam, peat, and sand. Cuttings will strike root in 

 sand, under a hand-glass, if kept free from damp.
