mediate between the parent species and also by the fact that np to date 

 no wild form of Bourquiniana has been found. 



Munson's derivation of the origin has not been accepted by either 

 French or American i)otanists. In this connection Bailey says: " It is 

 unassuniablc that a native grape distrilnited tlirough the Mediterranean 

 region could liave escaped for centuries the critical search of European 

 botanists and the knowledge of hundreds of generations of vignerons to 

 be (Hscovcred at last trans])lanted in the new world." Bush says: "This 

 rciniiids us forcil)lv of tlie 'Pedro Xiincncs ' (called also White Green Ries- 

 ling), which was believed to have been brought to Spain from the banks 

 of the Moselle bv the man whose name it bears. Count Odart, a celebrated 

 ami)elograph, wittily said: ' If he (Ximenes) took any he took .\ll, for no 

 siicli vine grows now north of the Pyrenees.' Thus we also think: If Mr. 

 Hour(|uiu took anv of the al)ove grapes he took .\ll, for no Herhcinont or 

 Lenoir can now l)e found native in Europe." 



The onlv northern variety of grape of any importance thcit is supposed 

 to have Bourquiniana blood is the Delaware,' and in this case only a 

 fraction of Bounjuiniana blood is presumably present. 



Bourquiniana can be propagated from cuttings more easily than the 

 t\pic;d Aestivalis but not so readily as Labrusca, Riparia or Vinifera. 

 Man\- of the varieties of Bourquiniana show a marked susceptibility to 

 mildew and black-rot; in fact, tlie whole Herbemont group is much inferior in 

 this respect to the Norton group of Aestivalis. The roots are somewhat hard, 

 bratK-h rather freely and are quite resistant to phylloxera.

-Jolin Eaton Lo Conte was born near Shrewsbury, Xew Jersey, in 17S4 and died at Philadelphia 

 in iSoo. In 1817 he entered the anny as a topographical engineer, and in 1S31 was retired with the 

 grade of major. Le Conte early became interested in natural history and his military expeditions 

 gave him ample opportunity for studying the flora and fauna of eastern America. He published a 

 number of important botanical papers, one of which was TIu- Vines of North Anu-^rica published in 

 1S54-55. His contributions to the genus Vitis will be found under that head.
