Solonis, and may be expressed by the number 16; its vigour, 

 as already mentioned, is higher than that of the majority of 

 American vines. In the chalks of Cognac this hybrid became 

 yellow, although not grafted, but without becoming stunted. 

 Its resistance to chlorosis is certainly inferior to that of 

 V. Berlandieri, but it might be of some value for compact, 

 fairly calcareous marls, for which it would seem to be indi- 

 cated on account of its strong roots. 



The Belton has strong, cylindrical canes, with numerous 

 whitish, fluffy hairs. Its leaves (Fig. 76) are plane, thick, 

 tough, the lateral lobes indicated by longer teeth, the termi- 

 nal lobe triangular; teeth sharp, normal to the limb, like 

 Monticola ; upper-face dull-green, araneous hair on the prin- 

 cipal and secondary ribs of the under-face. The consistence 

 of the parenchyma and the aspect of the leaf seem to indicate 

 a hybridizing action on the Berlandieri which would make the 

 Belton, therefore, a ternary hybrid. 



Hybrids of V. Candicans and V. Riparia. These 

 hybrids were indicated by Millardet and discovered by 

 H. Jaeger. Numerous wild forms of it are to be found in the 

 north of Texas, on the banks of the Red River, in very fertile, 

 sandy, red alluvials. It acquires, under these conditions, a 

 very great development of the canes, and fairly large dimen- 

 sions of trunk. An individual vine, cultivated since 1888 at 

 the School of Agriculture, Montpellier, has always had a 

 remarkable development in a blue non-chlorosing clay. This 

 hybrid may be of some value for compact clayey, but only 

 slightly calcareous, soils. It roots freely and has a large trunk. 

 Its leaves (Fig. 77) are large, plane, thick, orbicular, the five 

 lobes indicated by longer teeth ; petiolar sinus widely open, 

 with straight sides; upper- face deep-green, varnished; under- 

 face dull-green, with numerous patches of long, araneous hair 

 on ribs, petioles, and canes. Canes stout, vinous-brown, 

 straight. 



Hybrids of V. Candicans, V. Riparia, and V. Rupes- 

 tris (?). Certain forms of this numerous group of hybrids 

 are connected with Riparia X Candicans, in a -very distinct 

 way, in their ampelographic characters ; they constitute 

 what T. V. Munson considered as a species, the V. Novo- 

 Mexicana, and amongst them Solonis. 



The Novo-Mexicana of Munson comprises a group of vines, 

 rather than a unique form ; most of them are similar to
