158 AMERICAN VINES. 



in the wild state, in all the regions where the 

 V. Lincecumii grows mixed with these other species 

 (Missouri, Indian Territory, Arkansas, and north of 

 Texas) ; they are of no interest, for they are generally 

 very difficult to propagate from cuttings and only grow well 

 in siliceous, fertile soils. The Cordifolia X Lincecumii are 

 the most vigorous. T. V. Munson isolated two forms of these 

 hybrids which he named Black Jack and Ninon, they are 

 rather fructiferous, but of no value for our vineyards. 



Hybrids of V. Lincecumii and V. Rupestris. Fre- 

 quently met with in the south-west of Missouri, where H. Jaeger 

 studied them carefully. He also created a very great number 

 of forms, with the object of obtaining direct producers resist- 

 ant to black rot and mildew ; his numbers 43, 70, and 72 are 

 the most interesting, but the wines they produce are too 

 inferior in quality and -quantity to interest us; they always 

 retain the harsh taste characteristic of the Lincecumii grape. 

 Most of the -vigorous forms of these hybrids are difficult to 

 propagate from cuttings, and are inferior to the fine Rupes- 

 tris varieties, even as far as vigour is concerned ; they seem 

 to thrive well only in soils where the latter also grows 

 well. However, the V. Lincecumii is a species with large 

 trunk, great development, and some wild or artificial Lince- 

 cumii and Rupestris hybrids might be of value in Rupestris 

 soils. 



Hybrids of V. Bicolor and V. Riparia. Munson is the 

 only one who has observed this hybrid in Canada. It is a 

 tomentose Riparia, with leaves bluish on the under-face, 

 similar to V. Bicolor, and has only an interest as a curiosity. 

 The same applies to the 2Estwalis X Bicolor, which are 

 numerous in Pennsylvania arid Ohio, and have no cultural 

 value on account of their poor vigour. 



Hybrids of V. >stivalis and V. Cordifolia One of 



these hybrids was first discovered by J. E. Planchon ; they are 

 very numerous in the centre and extreme south of the United 

 States, and are only slightly vigorous, contrary to what 

 would have been supposed, on account of the influence of 

 V. Cordifolia. They have the general characteristics of the 

 small-leaved variety of V. Cordifolia, with patches of araneous 

 rusty-coloured hair on the veins. These hybrids have not 

 been tried in France ; we may infer from the properties of 

 their procreators that they have only a feeble resistance to
