The V. Monticola has probably a very great resistance to 

 phylloxera, and seems rather difficult to propagate from 

 cuttings. 



The V. Monticola has yielded a fairly large number of 

 wild hybrids with the species natural to Texas, which we 

 will study. Some viticulturists have attributed to many 

 vigorous forms of Rupestris an hybridizing influence of 

 V. Monticola; this seems very difficult to admit generally, 

 especially if we take into consideration that the V. Rupestris 

 and V. Monticola live, in their wild state, in regions very far 

 apart. 



The V. Monticola is, without doubt, an excellent element 

 in the creation of Franco-American hybrids especially 

 if combined with varieties of great vigour and strong 

 development. 



The principal forms of V. Monticola selected and named in 

 the collection at the School of Agriculture, Montpellier, are 

 actually fairly numerous; we will only give the essential 

 characters of the principal forms. Amongst these, the 

 Monticola Salomon and Monticola Munson No. I are very 

 vigorous, leaves intense green, canes strong and long, trunk 

 stout. They appear to be the best, and are probably the 

 most resistant to chlorosis. 



Monticola Salomon. Stump very vigorous; canes strong, 

 long; rather numerous and erect ramifications; internodes 

 fairly short, finely striated, of a light-green colour in the 

 herbaceous state, of a brownish -yellow colour with deeper 

 stripes when lignified; young leaves bright green, very 

 shining; adult leaves (Fig. 47) relatively large, entire, exces- 

 sively thick, sub-cordiform, very wide towards the petiole, 

 terminal lobe triangular, well-defined, folded along the three 

 principal ribs, with margins irregularly rising towards the 

 top forming a cup; petiolar sinus, very deep, with sides tan- 

 gent or overlapping; upper-face intense green, as if var- 

 nished; under-face lighter green, very lustrous; ribs very 

 stout, with fluffy hair at the points of bifurcation. Petiole 

 very short, forming a right angle with the limb, with patches
