Doubts have been entertained, among fome botanifts, whether this plant is the Clematis viorna of 

 Linnaeus, as given by him, with various fynonims, in his Sp. Plan. By collating the different fpecific 

 characters from the fynonims adopted by him, we have no hesitation in our decilion. Being a native 

 of Virginia and Carolina, it is not fo hardy as fome others from the northern parts of Europe or 

 America; but, nevertheless, is not kilied by our winters, as it is herbaceous, and not making its fhoots 

 till late. In a warm fituation againft a wall or trellis, it will begin to bloflbm in July, and continue 

 to flower till deftroyed by the firoft. As yet it is rather fcarce in our gardens, being but of a late 

 introduaion, though long known by defcription. Our figure was taken at the Hammerfmith mtrfcrv, 

 where it is in high perfection, being planted in a mixture of loam and peat earth: it is mofi readily 

 increafed, by parting the roots in (bring; as the feeds feidom come to maturity in this climate.
