BENCH-GRAFTING RESISTANT VINES. 247 



-appearance), of a light nut colour, smooth, rather shining, 

 and a little pruinose near the eyes when the wood is well 

 ripened ; young shoots of a light purple ; leaves large to very 

 large, thick, elongated, somewhat bulging between the main 

 nerves, dark green and shining on the upper surface, lighter 

 green on the under side, with a few stiff hairs on the ribs ; 

 the petiolar sinus is open, U-shaped ; the upper lobes are 

 well marked by large elongated teeth, the lower barely 

 marked at all ; the teeth are sharply pointed and in two 

 series (see figure on title page); the roots are slender and 

 spreading like all varieties of Riparia (see Fig. 183). Re- 

 sistance to phylloxera, 18. 



Rupestris da Lot. (Synonyms Rupestris St. George, 

 Rupestris Phenomene, Rupestris Sijas, Rupestris Monticola, 

 Rupestris St. George erige, Rupestris Lacastelle, Rupestris 

 Colineau, Rupestris Reich, Rupestris Richter.) This variety 

 is extremely vigorous and produces a very strong thick 

 stem ; canes erect (the main laterals spreading), with short 

 iuternodes and prominent nodes ; leaves small, wider than 

 long, with metallic sheen, undulating edges, and relatively 

 thin, those of the laterals often very small and somewhat 

 bronzed at the tips. In hot weather the leaves fold in two at 

 the mid-rib, but less than most varieties of Rupestris. The 

 roots are long and strong, and not so slender as those of 

 other varieties of Rupestris. Resistance to phylloxera, 16. 



Soloms. A vigorous strong grower ; canes spreading, 

 with patches of whitish hairs, which become light brownish 

 grey in autumn ; leaves of medium size, upper lobes marked 

 by very long teeth, lower lobes lacking ; teeth very long 

 acuminate, in two series ; petiolar sinus widely open. The 

 leaves are covered with white web-like hairs when young, 

 becoming almost glabrous when old, except on the ribs and 

 petiole ; roots strong and intermediate in direction between 

 those of Riparia and Rupestris (see Fig. 183). Resistance to 

 phylloxera, 14. 



SUMMARY. 



1. Every grape-grower should insure against phylloxera 

 ty testing the most promising resistant vines on his own 

 place, and by learning the niethods of bench-grafting. 



2. Jt is unsafe to attempt operations on a large scale with 

 cuttings imported from abroad, on account of the danger of 

 injury to such cuttings on the journey.
