318 MANUAL OF AMERICAN GRAPE-GROWING 



It is seldom used for this purpose, however, on account of the 

 difficulty of propagating it by means of cuttings. For the 

 same reason vines of it are seldom found in cultivation.

Vine vigorous, climbing ; shoots more or less angled and pubescent ; 

 pubescence remaining only in patches on mature wood ; canes mostly 

 with short internodes ; diaphragms thick ; tendrils intermittent, long, 

 strong, bifid or trifid. Leaves with small stipules ; leaf-blade large, 

 broadly cordate, notched or shortly three-lobed ; petiolar sinus rather 

 open, V- or U-shaped, margin with broad but rather shallow teeth, 

 rather dark glossy green above, grayish pubescence below when 

 young ; becoming glabrous and even glossy except on ribs and veins, 

 when mature. Clusters large, compact, compound, with long peduncle. 

 Berries small, black, with thin bloom, juic\', rather tart but pleasant 

 tasting wlien thoroughly rii)e. Seeds few, small, short, plump, oval 

 or roundisli, with short beak; chalaza oval or roundish, distinct; 

 raphe narrow, sHghtly distinct to indistinct. Leafing, flowering and 

 ripening fruit very late. 



Berlandieri is a native of the limestone hills of southwest 

 Texas and adjacent Mexico. It grows in the same region with 

 r. nionticola, hut is less restricted locally, growing from the 

 tops of the hills down and along the creek bottoms of these 

 regions. Its great virtue is that it withstands a soil largely 

 composed of lime, being superior to all other American species 

 in this respect. This and its moderate degree of vigor have 

 recommended it to the French growers as a stock for their cal- 

 careous soils. The roots are strong, thick, and very resistant 

 to phylloxera. It is propagated by cuttings with comparative 

 ease, but its varieties are \'ariable, some not rooting at all 

 easily. While the fruit of this species shows a large cluster, 

 the berries are small and soiu*, and Berlandieri is not regarded 

 as having promise for culture in America.
