smooth: often pubescent on Mississippi Kiver; tendrils rather weak; 

 diaphragm thinnest of any species, being not much thicker than writing 

 paper; accidentally hybridized with Labrusca in Kentucky gave the 

 Taylor. No vines of pure blood are yet cultivated for profit. 



(b) Eupestris (Sand-beach, or Sugar Grape). 



From P^ast Tennessee westward, in the hilly regions, to Southwest 

 Texas, fast disappearing by the browsing of stock. Leaves reniform, 

 smooth, coarsely toothed ; wood dark gray, smooth, slender, much 

 branched and spreading gooseberry-bush fashion naturally, but if 

 trained makes a good vine, but requires much pruning; tendrils 

 very small and weak, soon disajjpearing after first year. Mr. H. Jae- 

 ger is the only one who has introduced anj- varieties into cultiva- 

 tion. His Nos. 59, 60, 62, 6i, etc., found wild, make a fine claret, and 

 offer a fine start to hybridize 'upon, which he has successfully done 

 already with promising results. Huntingdon is an accidental hybrid, 

 containing a large portion of Rupestris blood and some Eiparia. 

 The earliest of all species to ripen ; fruit usually larger than Riparia, 

 but cluster smaller ; fruit perfectly resistant to rot, and may give a 

 valuable strain of varieties, free from this more threatening trouble 

 than philloxera, to the Vinifera and most Labrusca and many .Ksti- . 

 valis. 



(c) Nuevo Mexicana (Prof. Lemmon) (Woolly Riparia). 

 Northwestern Texas ("The Panhandle") and New Mexico, in sandy 

 ravines and canyons. Leaves cordate or nearly round, with coarse, 

 sharp, or blunt teeth, more or less woolly, especially when yo.ung, 

 leathery and enduring; wood light gray, and quite woolly when 

 young; erect, shrub-like, with wiry, deeply penetrating roots in the 

 fashion of a tree with taproot; grows naturally in thickets, like bushes 

 without support, having small tendrils, but when brought into lower 

 timber lands makes strong climbing vines; fruit and seed larger than 

 the Northern Riparia; quality most excellent, very sugary ; offers most 

 excellent stock for the experimenter. The writer has varieties with 

 fruit one-third of an inch in diameter. This form gradually runs into 

 the next, which has a great similarity in habit of growth, with larger 

 fruit-clusters. It is termed 



{(i) Arizonica (Arizona Grape). 



Leaves round cordate, coarsely and regularly acute toothed, smooth or 

 l)ubescent, seeds much like the woolly form, wood gray, or reddish 

 gray, smooth, or pubescent when young. Fruit excellent, 



2. CORDIFOLIAN GROUP. 



Late to leave out, bloom and ripen; wood and leaves smooth, diaphragm 

 thick ; fruit in long, many-berried clusters, vei'y small, mostly seed and 

 skin ; roots wiry and resistant; found mostly in bottoms.
