BOTANICAL CHARACTERISTICS. 5 



GROUP 1. RIPARLE. (River Grape.) 



Vine shrubby or climbing, moderately bark-shedding 

 in fibrous plates ; young canes cylindrical, or but slightly 

 angled ; smooth or tomentose ; tendrils rather short and 

 weak ; leaves small to medium, broadly heart-shaped ; 

 clusters small, generally compact shouldered; fruit- 

 stalk very short and thick; berries small to medium, 

 with bloom vinous and without offensive odor. 



Vitis rupestris, Scheele, Southwestern Texas, Ozark-Ridge; Central 



Tennessee. 

 Vitis riparia, Michaux, all Northern States and Canada east of Rocky 



Mountains. 



Vitis Solonis, Hort. Berol., Northwestern Texas and New Mexico. 

 Vitis Doaniana, Munson, Northwestern Texas and New Mexico. 



GROUP 2. WESTERN SPECIES. 



Vine shrubby, as in Vitis Arizonica, or climbing 

 vigorously, as in F. Californica. Young canes nearly 

 cylindrical, tomentose, buds small to medium and whit- 

 ish tomentose in expanding. Leaves long, cordate, or 

 heart-shaped, small to medium silky tomentose to glab- 

 rous ; clusters small to medium, mostly compact. Ber- 

 ries small black, with thin bloom, vinous, and hanging 

 a long time to the vine. The foliage said to be very 

 sensitive to mildew, and the fruit to rot. The F. Cal- 

 ifornica is the tenderest of all our native species, most 

 abundant in light soils along streams. 



Vitis Arizonica, Engelmann, var. glabra, Munson, Western Texas, New 



Mexico, Arizona, and Chihuahua, Mexico. 

 Fitis Girdiana, Munson, all California south of Mojave Desert, rare 



north of that. 

 Vitis Californica, Bentham, Central and Northern California, and 



Southern Oregon on Rogue River. 



GROUP 3. CORIACE^E. (Thick Leaved.) 



Vine rather slender, climbing, young leaves very 

 small on end of growing shoots. Young annual canes 

 white or rusty tomentose, except in F. Champini. 

 Leaves medium, broadly cordate. Surface slightly
