cate at base of leaf, with little or no cilia on the margins, unevenly large-toothed 

 with sharp or mucronate points, with 2 prolonged acuminate erect lateral lobes; 

 leaves of vegetative shoots larger and with 3 or 5 long-acuminate lobes with broad 

 rounded sinuses; upper leaf surfaces shining dark-green and glabrous except on 

 veins, the lower surface pale and usually retaining pubescence on veins with tufts 

 in the axils; petioles red; thyrse 5-15 cm. long, long-stalked, rather open, its 

 rachis and branches copiously hirtellous; grapes 5-10 mm. in diameter, black or 

 bluish-black, without bloom, the skin thick, finally sweet; seeds 4.5-6 mm. long. 



On margins of ponds or sloughs, or in low woods in e. Tex. and s.e. Okla. 

 (Waterfall) , fruiting Sept.-Oct.; from La. and Tex., n. to Ind., 111. and la. 



5. Vitis arizonica Engelm. Canyon grape, gulch grape, parra del monte. 



Grayish more or less shrubby vine, mostly small and weak, much-branched, 

 usually not high-climbing; young parts ashy-gray from a tomentum to essentially 

 glabrous; diaphragm 2-4 mm. thick; stipules 2-3 mm. long; tendrils soon deciduous 

 if not attached; leaves broadly cordate-ovate to nearly reniform, with a triangular 

 apex. 5-12 cm. long above the petiole and mostly slightly broader than long, the 

 basal sinus from narrowly inverted U-shaped to broad and open, the margins with 

 rather small or rarely large sharp and mucronate uneven teeth, commonly obscurely 

 lobed or shouldered, rarely deeply 3-lobed, at first both sides cottony, with age the 

 upper surface becoming indifferently floccose and the lower surface more or less 

 permanently covered with grayish-white short erect hairs, the lower surface also 

 commonly becoming glabrous and somewhat glossy except for a usual tuft of erect 

 hairs in the vein axils; petioles often pink-tinged and either slightly floccose or 

 glabrous; thyrse 5-10 cm. long, slender-stalked, the short peduncle and rachis 

 more or less floccose to subglabrous; grapes 6-10 mm. thick, black and sometimes 

 with a thin bloom, the skin thin, the pulp juicy and sweet; seeds 4-6 mm. long, 

 3-4 mm. broad, short-beaked. 



Climbing on trees, shrubs and over boulders along streams and in canyons of 

 mts. in the Tex. Trans-Pecos, N.M. (widespread) and Ariz. (Navajo, Coconino 

 and Mohave, s. to Greenlee, Cochise, Santa Cruz and Pima cos.), fruiting Aug.- 

 Oct.; from Tex. to Ariz, and n. Mex. 



The leaves of var. arizonica are usually smaller and their lower surface is more 

 or less permanently covered with short straight whitish hairs, whereas the var. 

 glabra Munson (V. Treleasei Munson) has leaves to 12 cm. long and their lower 

 surface is essentially glabrous or the vein axils are provided with small tufts of 

 short straight hairs. 



Kearney and Peebles has the following to say about this species. "The berries 

 are of good quality for jelly and grape juice and are much eaten by birds. They 

 are also eaten, both fresh and dried, by the Indians. The vines are useful in check- 

 ing erosion along creeks. The leaves when chewed allay thirst." 



6. Vitis vulpina L. Fox grape, winter grape, frost grape, chicken grape. 

 Vigorous high-climbing vine with stout trunk; young growth glabrous or soon 



glabrate, the branchlets terete; diaphragm 2-6 mm. thick; stipules 5-8 mm. long; 

 leaves of fertile branches thick-herbaceous, broadly cordate-ovate, usually with a 

 long sharp apex, 8-18 cm. long from petiole, longer than wide, the basal sinus 

 prevailingly broadly inverted U-shaped, coarsely and sharply irregularly toothed, 

 unlobed or merely with angled shoulders, upper surface bright-green and lustrous, 

 lower surface lighter-green and usually glabrous except for short straight hairs on 

 veins and as tufts in the axils of veins; petiole shorter than blade, usually with short 

 straight erect or spreading hairs; thyrse loose and open, to 2 dm. long; fruiting 

 pedicels about 5 mm. long; peduncles sometimes with an early-deciduous tendril; 

 grapes black and shining, often glaucous, 5-10 mm. in diameter, persistent, edible 

 after frost; seeds 5-6 mm. long, 4-5 mm. thick.
