FIG. 3. Rupestris Martin. One half natural size. 



the Riparia Gloire is to be 

 preferred to the present or 

 other varieties of this species. 



Rupestris Martin (Fig. 3). 

 Very vigorous and one of 

 the most robust of the exist- 

 ing stocks. Leaves larger 

 than those of Rupestris St. 

 George, and with a V-shaped 

 petiolar sinus. Canes 

 glabrous, pinkish, long and 

 thick. 



Roots easily, but is more 

 difficult to graft than St. 

 George. The grafts which grow are very satisfactory and are less 

 liable to coulure than grafts on St. George. It succeeds in drier situa- 

 tions than the latter. 

 Male vine. 



Rupestris St. 

 George (Fig. 4). 

 Perhaps the most 

 vigorous of all the 

 stocks grown when 

 planted in suitable 

 locations. Leaves 

 small ; the petiolar 

 sinus very open, 

 with a j -shaped out- 

 line. Canes and 

 trunk very thick 

 and robust. 



This variety roots 

 and grafts with 

 great facility, and 

 grows at least as 

 large as any scion 

 which is grafted on 

 it. Succeeds in any 

 soil except those un- 

 derlaid with an im- 

 permeable or stiff 

 clay subsoil.
