 the feeds of this plant were lent by ProfelTbr P. Pallas, from Siberia, to MefTrs. Lee and Kennedy, of 

 Hammerl'mith; at whofe nurfery the drawing of this nioft charming plant was made: though a 

 native of fo cold a clime, it feems with difficulty to endure the feverity of ours; thriving bell in a pot, 

 under any flight llielter, or a very dry fituation if planted out: it is increafed by the root, which 

 fliould be parted in March ; and flowers in June, and July.
