IN AMPELOGKAPHY. 77 



Riparia Gloire. 



VITIS RIPARIA.* AMERICA. 



LEAVES. Very large, rounded, flabby, relatively dull ; 

 parenchyma generally curved up between 

 the principal veins. This latter character 

 is especially noticeable in leaves developed at 

 the moment when growth is in full activity. 



WOOD. Flat near the nodes ; bark very thin and very 

 smooth, hazel colour ; buds very large ; 

 secondary ramifications not very numerous. 



* The Vitis Riparia present the following descriptive characters : 



LEAVES. Flat, thin, supple, cordiform-emarginate ; lobes indicated by 

 more prominent teeth, no woolly hair, stiff hair on the veins 

 of the under face ; teeth sharp. 



UPPER PORTION OF GROWING SHOOT. Bent as shown in the 

 figure, terminal bud completely enveloped by the young 

 leaves. 



Young leaves, folded along the mid-rib. 



WOOD. Cylindrical, very smooth, extremely long, growing rapidly in 

 length. Canes of almost even diameter for the whole 

 of their length. By simply examining the canes at their 

 point of insertion one would not suspect the vegetation of 

 the stump, for the canes are small in number, and their 

 diameter is relatively small at the base ; very few secondary 

 ramifications, nodes only slightly prominent, internodes long, 

 bark exfoliating very easily in fine strips like hemp. The 

 wood in its herbaceous state is so smooth and glossy (except 

 for Tomentose Riparias), and seems so supple, that it 

 appears made of drawn or stretched iiidiarubber. 



GRAPES. Florescence very early, flowers generally male.
