IN AMPELOGEAPHY. 65 



Monticola (Vitis) 



AMERICA. 



LEAVES. Small, thick, parchment like, very shiny on 

 both faces, margins always undulating, 

 and often curled upwards. 



Teeth neatly cut (sharp), divergent, wide, 

 short without being rounded. 



Petiole covered with hair, lying flat. 



WOOD. Before lignification covered with hair, lying 

 flat; after lignification reddish-brown, often 

 finely cracked ; secondary ramifications 

 numerous. 



The diverse forms of this species are distinguished by the 

 dimension, thickness, and colour of their leaves, the more or 

 less abundant hair, lying flat, on the herbaceous shoots, and 

 by the colour of the ripened wood, which varies from red to 

 brown-greyish. Certain varieties have slightly uneven 

 leaves ; others have leaves with margins very strongly 

 curled upwards.
