A doiible-flowered variety, still cultivated in gardens, was found wild in England in 

 Ray's time, by D. Lawson, (Synops. 2 éd., 1696, p. 154), but it may have been known as a 

 garden plant before that time, as it is described by C. Bauhin (1671). Sir .7. Hooker refers 

 the double variety to C. Guerengerii, probably C. riparia, Don.
