THE GRAPES OF NEW YORK. 



peduncle slender, of medium length. Berries black, small to medium in size; pleasant 

 in taste. Seeds two to three of medium size; chalaza oval in shape, slightly distinct; 

 raphe flat, usually inconspicuous, rarely prominent. 



Arizonica was named and first described by Engelmann in 1868. It 

 was later described by Parry, botanist of the Department of Agriculture, 

 from specimens sent to him by Dr. Charles Smart, an army surgeon sta- 

 tioned in southern Arizona, in 1867. Parry says that Engelmann considered 

 it a distinct species and had provisionally named it Vitis arizonensis. As 

 to the name, this is evidently an error in quoting Engelmann. 



Its habitat is " Western Texas, New Mexico, Arizona, Chihuahua 

 (Mexico), and South Utah." 



This grape is adapted only to the arid districts of the West. When 

 raised in humid climates it is subject to the attacks of mildew and black- 

 rot. As might be expected from its habitat, it endures intense drouths. 

 It grows well on limestone, pebbly, or alluvial soils. It has a considerable 

 degree of resistance to phylloxera, grows readily from cuttings, and according 

 to Munson, can withstand zero temperature without injury. As the Euro- 

 pean grapes can be raised in its native country, it is not there regarded as 

 valuable, although the fruit is said to be rich in sugar and to be of pure 

 flavor. It has been used in California as a stock, but is not regarded in 

 any section very favorably and its use has never become extensive probably 

 owing to its lack of vigor. It suckers less than Rupestris. Arizonica blos- 

 soms about the time of Labrusca. It is of no value to the grape-growers 

 of the East and probably of none to those of the West.

Vitis arizonica glabra was named liy Munson in 1S90. It differs from 

 the regular fcirm in having gloss\', glabrous leaves which are mostly larger 

 and thinner. The variety is found in the region from Albuquerque, New 

 Mexico to Truxton, Arizona, and northward into southern Utah.
