I/O AMERICAN VINES. 



Hybrids of V. Rupestris and V. Rioaria. These were 

 discovered by H. Jaeger in the forests of the tribes of Senasqua, 

 Wyandotte, Modoc, Shawnee, Quapaw, Paola, Ottawa, and 

 Miami, of Indian Territory. The most interesting forms of 

 these hybrids have been classified ; they are -very numerous in 

 the wild state, and over 100 forms have been selected, some of 

 which have real value.

 more vigorous than their progenitors, they rapidly increase 

 in diameter and the canes become longer and stouter, and, 

 moreover, accommodate themselves to poorer soils than
