AMERICAN VINES. 



T. V. Munson has isolated two forms of these hybrids. 

 One, the Gwyn grape, of the County of Lampasas, has 

 medium, thin, lustrous leaves, with small patches of fluffy hair 

 on the ribs of the under face, wide triangular sharp teeth. 

 The other, the Sanford grape of the County of Bell, with 

 small, thick, slightly tri-lobed, elongated leaves, plane, with 

 very abundant whitish tomentum on the petiole and shoots, 

 long hair on the principal ribs of the upper-face, and 

 araneous patches of hair on all the veins of the under-face. 

 These characters show that in these two forms which root 

 freely from cuttings, according to T. V. Munson, the Mus- 

 tang predominates, which may throw doubt on the value of 

 these cepages which have not been tried in France. 



Belton. This is the most interesting hybrid of this 

 group, although it is rather difficult to propagate by cut- 

 tings. Its resistance to phylloxera is superior to that of
