30 GRAPE CULTURE AND 



readily from cuttings; vine makes a good grafting stock, but 

 is apt to sucker; roots thin and wiry, resistant. 



5. Arizonica. Arizona and New Mexico. Resembles 

 Rupestris very much, but is a more upright grower. Does 

 not seem to take the graft readily, and has not so far full- 

 filled the expectations of its disseminators. 



6. Californica. Generally found wild along all the streams 

 of this State, where it often attains very large size. Wood 

 grayish, long jointed, a strong grower, with thick, fleshy, 

 soft roots, which go straight down. Leaves heart shaped, 

 downy and wooly; berry small, black, without pulp, but very 

 large seeds. It takes the graft readily, and, should it prove 

 entirely resistant, which is not fully proven yet, will make a 

 valuable stock on deep, moist soils, while not so well 

 adapted to dry hillsides. 



7. Vitiifera. To this class belong all of our leading varie- 

 ties. It is the old European or Asiatic grape. Too well 

 known here to need any more minute description. 



This much seemed to be necessary to give the reader a 

 clear understanding and avoid repitition and minute descrip- 

 tion. Those who wish to investigate this subject further will 

 find the essay by Mr. T. V. Munson, on 'Native Grapes of 

 the United States, read before the American Horticultural 

 Society, very interesting, which can be obtained from the Sec- 

 retary, Prof. H. VV. Ragan.
