4 2 AMERICAN VINES. 



L SPECIES OF AMERICAN VINES. 



America is the part of the world which possesses the 

 greatest number of species of vines; the numerous types 

 derived from them are disseminated in all situations and con- 

 ditions. Eighteen species of American vines, at least, are 

 known, while only one exists in Europe, and eleven in Asia. 

 The species from America alone resist more or. less the 

 attacks of phylloxera, and this resistance is probably the 

 result of natural selection determined by the action of the 

 parasite itself. This natural selection is, therefore, a guar- 

 antee of the permanence of the resistance acquired by each 

 of them. 



Amongst the eighteen species of American vines, a few 

 only are of cultural value for our vineyards. It is not 

 useless, however, to know them all, for certain species of no 

 intrinsic value have given, by direct or indirect hybridization, 

 cpages which have or have had a certain reputation. We 

 will study the species of American vines in the following 

 order, in which they are grouped according to their botanical
