GENERIC SYNOPSIS OF THE NATIVE GRAPES OF THE UNITED STATES OF 



NORTH AMERICA. 



By T. V. Munson. 



Section I.-tEUVITIS, Planchon. 



Bark, shedding in fibrous plates, outer bark on annual wood dis- 

 tinctly striated, without lenticels; tendrils forked ; nodes provided 

 with diaphragm, internodes with true pith ; flowers clustered in a true 

 thyrsus ; seeds pyriform. 



Series 1. Ripariee, Planchon. 



Plant : shrubby or climbing moderately ; seedlings first year erect 

 or ascending, very vigorous; tips of young growing brandies more or 

 less enveloped in quickly enlarging, but slowly unfolding young leaves. 



Roots: one-year seedlings axial, tapering from collar downward; 

 branches slender, wiry, rarely tranversely wrinkled, resistant to Phil- 

 loxera. 



Wood: annual, cylindrical, or slightly angled, smooth or tomentose; 

 diaphragm thin and plane; tendrils short, bifid, rather weak, intermit- 

 tent, soon shed if not clinging to some object ; buds mature or dor- 

 mant, small. 



Leaves: stipules large, lanceolate, membranaceous; blade small to 

 medium, broadly cordate, folding or cupping toward upper face; basal 

 sinus broadly or narrowly fl-shaped, except in V. rupestris very broad, 

 yet acute at insertion of petiole. 



Clusters : small, generally compact, shouldered; peduncle very short ; 

 pedicels thick. 



Berries: small to medium in V. Doaniana, bearing much prunose 

 bloom, vinous and pure in taste; persistent. 



Seeds : with small or depressed chalaza and raphe ; germination quick. 



Germination, foliation, inflorescence, ripening of fruit, very early; 

 growth from cuttings easy; native on high sand-banks along rivers, 

 lakes, and beds of sandy ravines; in cultivation doing well in any but 

 very limy soils ; exceedingly hardy in icithstanding cold.
