The Agricultural Gazette, of Xew South Wales, for August, 

 1906, contains an interesting article entitled "A New Potato 

 (Solanion commersoni) S' The wild plaut is native along the wet 

 banks of the ^Nfercedes Piver, iu Pruguay, where it was discov- 

 ered more than a century ;igo. After several years of experi- 

 ments with tubers of a mutated plant, (n'iginally from the Mer- 

 cedes, M. Lobergerie, of Vienna, has obtained many interesting- 

 variations, of which several types have been definitely fixed. A 

 violet varietv is remarkable in that it produces a much heavier 

 growth of tuliers and of tops than the common potato, is entirely 

 immune to potato l)light ( Ph ijlopl) thorn uifestans), and the tops 

 are resistant to two deiirees C. of frost. The flavor of the tubers 

 is said to be excellent, there being no bitterness even in the green 

 aerial ones, the (levelo]miout of whicli is (piite characteristic of 

 tlio variety.
