(B). FORMS DERIVED FROM V. RIPARIA; 



The forms derived from V. Riparia seem to have been 

 exclusively used as stock, for while the peculiar taste of 

 their grapes and their small fertility, prevent them from 

 being used for the direct production of wine, the facility with 

 which their cuttings root, the small cost of their canes, the 

 rusticity of most of their forms, and, .finally, the ease with 

 which they may be grafted with most of the European 

 varieties, give them a prominent rank for that purpose. 



Two wild forms of this species occupy an important 

 place in the vineyards recently reconstituted. They are 

 the Riparia Gloire de Montpellier and the R. Grand Glabre. 

 Different hybrids, resulting from various crossings, more 

 particularly from crossings with V. Labrusca, were used at 

 first by the Americans. Such are Solonis, Clinton, Taylor, 

 Vialla, Elvira, and Noah. However, they do not occupy a 

 very large area in the new vineyards, but are to be found 

 in certain special situations. 



RIPARIA GLOIRE DE MONTPELLIER. 



Synonyms: R. Gloire, R. Portalis,R. Michel, R. Saporta^ 

 &c. This Riparia was imported for the first time by L. 

 Vialla, on the property of Portalis belonging to Michel. 

 He drew attention to its vigour, which wa's far superior 

 to that of other known types. He multiplied it on hi& 

 property at Saporta. Extended experience has confirmed 

 this opinion, and it is now multiplied almost exclusively 

 among the forms of this species, for the purpose of recon- 

 stituting vineyards. Its resistance to phylloxera is 19. 



Description. Very vigorous plant, spreading habit, trunk 

 of medium size (rather large for a wild Riparia), canes long 

 with long internodes, medium in size, flat near the nodes, 

 light hazel colour, with a very thin and very smooth bark, 

 covered with bloom, and with very few secondary ramifica- 

 tions. The young shoots are of a light purple colour. The 

 adult leaves are very large, rounded, dull, with limb 

 regularly goffered between the ribs of the upper-face,, 

 and with stiff hair on the veins of the under-face. Petiolar 

 sinus having the shape of a U ; sharp teeth ; young 

 leaves folded along the mid-rib (Fig. 14) ; flowers 

 generally male.
