240 PROCEEDINGS OF THIRTY-THIRD FRUIT-GROWERS * CONVENTION. 



and of the soils and conditions in which they thrive best, should come 

 very near telling us that. To illustrate: some of the principal charac- 

 teristics of the native species of most value as resistants and direct pro- 

 ducers are herewith given: 



Vitis riparia is vigorous on moist soils only, and its varieties attain 

 their best growth on sandy, fresh banks of rivers. They root easily 

 from cuttings, graft well, and are very susceptible to drought. 



Vitis rupestris is found in hilly, mountainous country, nearly always 

 along gravelly banks and ravines where there is moisture all the year 

 around but where water abounds only a portion of the time. Its vari- 

 eties should never be planted where there is stagnant water. Their 

 resistance to drought is good, they root easily from cuttings, bench 

 graft readily, but are very difficult to handle as field grafts. 



Vitis sestivalis varieties delight in high, .warm, sandy and gravelly 

 moist soils, and are rarely found in very dry soils and never in swampy 

 lowland or lime soils. They are good growers, very fruitful, hard to 

 root from cuttings, and graft well in vineyard. 



Vitis linceumii is found in sandy, high, well-drained timber lands on 

 ridges in siliceous or granitic gravel mixed with clay, rather compact 

 soils, and also in very deep soils on river banks. It is very resistant 

 to heat and drought, is a good grower, quite fruitful, but hard to root 

 from cuttings. 



Vitis bicolor varieties grow well on black sandy soils derived from 

 old formations. Moderately good growers, fruitful, very resistant to 

 heat, drought and cold, and hard to propagate from cuttings. 



Vitis berlandieri is found in limestone hills, on top of and along the 

 side of hills, on creek bottoms. Its varieties are of the most resistant 

 to lime, drought, and phylloxera. They graft easily and are good 

 graft bearers, but most varieties of them are exceedingly hard to root. 



Vitis monticola is also found on limestone hills. Its varieties grow 

 exclusively on low mountains or on tablelands — never in low places. 

 They are resistant to heat and drought and graft well; exceedingly 

 hard to root from cuttings. 



Vitis cordifolia is found on soils similar to those in which the Riparia 

 is found. Its varieties are vigorous growers and graft well, but are 

 very hard to root from cuttings. 



Vitis champini is found in the limestone hills of Texas. Its varieties 

 adapt themselves to a variety of soils, stand heat, drought and lime 

 conditions well, are good growers, root easily from cuttings and graft well 

 in vineyard. 



Vitis solonis is found in ravines, along banks of streams. Its varieties 

 are of fair growth on sandy or lime soils and root easily. 



Vitis doaniana varieties are moderate growers, do well on sandy or 

 lime soils, root pretty easily from cuttings, stand heat and drought well, 

 and graft well in vineyard.
