754 VITACEAE 



beneath, somewhat glaucescent on both sides, broadly cordate at the base ; petioles somewhat 

 shorter than the blades, often woolly like the branches : panicles 2-10 cm. long, slender, 

 not dense : berries subglobose, 7-14 mm. in diameter, purple-black, somewhat glaucous, 

 pleasant-tasted : seeds pear-shaped, 5 mm. long, each with a conspicuous raphe. 



On river banks and hillsides, Pennsylvania to Maryland and Texas. Spring; fruit ripening in 

 August. Sand Grape. Sugar Grape. 



2. Vitis montlcola Buckl. A slender trailing or high-climbing vine, sometimes 10 

 m. long. Leaf-blades thinnish, 5-10 cm. in diameter, orbicular or reniform, glabrous 

 in age, acute at the apex with an often prolonged tip, coarsely toothed and often 3-lobed, 

 dark green and lustrous above, often shining beneath and gray-green, cordate at the base, 

 on rather short more or less woolly petioles : panicles 3-8 cm. long : berries subglobose, 

 12-14 mm. in diameter, black or paler, sweet : seeds rather broadly pear-shaped, 5-7 mm. 

 long, each with a conspicuous raphe. 



In sandy or lime soil, Texas. Spring ; fruit ripening in September. Mountain Grape. 



3. Vitis Champinii Planch. A climbing vine. Leaf -blades thinnish, broader than 

 long, more or less reniform, 5-10 cm. broad, rather shiny above, coarsely toothed and some- 

 times indistinctly 3-lobed, glabrous at maturity, cordate at the base ; petioles a little more 

 than i as long as the blades: panicles 2-10 cm. long: berries globose, fully 15 mm. in 

 diameter, black, with a slight bloom, pleasant-tasted : seeds pear-shaped, 0-7 mm. long, 

 .each with a conspicuous raphe. 



In valleys and on hillsides, Texas. Spring ; fruit ripening in September. 



4. Vitis cordifolia Lam. A very vigorous high-climbing vine, the stems sometimes 

 •obtaining a diameter of 3-6 dm. Leaf-blades thin, deep green, longer than broad, com- 

 monly ovate in outline, rarely 3-lobed or 3-angled near the apex, rather coarsely and 

 irregularly toothed, glabrous or sometimes sparingly pubescent beneath, more or less 

 ■deeply cordate at- the Ijase, long-petioled : panicles 1-3 dm. long, commonly drooping : 

 berries globose, 8-10 mm. in diameter, black, under a slight bloom, pleasantly acid, or 

 fetid-aromatic, persistent : seeds broadly pear-shaped, 5-6 mm. long, each with a con- 

 spicuous raphe. 



In woods and thickets. New York to Kansas, Florida and Texas. Spring ; fruit ripening in Sep- 

 tember and October, especially after frost.— Two varieties of this species have been recognized : V. cor- 

 difolia foHida Engelm., a native of the Mississippi valley produces fetidly aromatic berries : V. cordifolia 

 semptrvirens Munson, a native of peninsular Florida bears rather persistent leaves with lustrous blades, 

 sometimes suggesting those of V. palmata. Frost Grape. Chicken Grape. 



5. Vitis H611eri (Bailey) Small. A high-climbing vine. Leaf -blades bright green, 

 thin, suborbicular to ovate-orbicular, 5-10 cm. in diameter, mostly rounded at_ the apex, 

 more or less pubescent on the nerves beneath, crenate, the teeth mucronate ; petioles about 

 ^ as long as the blades : panicles many-flowered, 5-10 cm. long, short-peduncled : berries 

 not seen. [ V. cordifolia var. H4kri Bailey.] 



In thickets and on hillsides, Kerrville. Texas. Spring ; fruit ripening in August or September. 



6. Vitis Baileyana Munson. A high-climbing vine, the stems with short internodes 

 and often many short branches. Leaf-blades thinnish but firm, ovate or orbicular-ovate, 

 5-10 cm. long, glabrous and somewhat rugose above in age or pubescent on the nerves be- 

 neath, toothed, otherwise entire or angularly 3-lobed near the apex, cordate at the base : 

 panicles 8-13 cm. long, compact : berries globose, 7-10 mm. in diameter, black, destitute 

 of bloom or nearly so : seeds broadly pear-shaped, sometimes nearly as broad as long, 3-4 

 mm. long, each with a conspicuous raphe. 



In woods and on mountain slopes, Virginia and West Virginia to Georgia and Alabama. Spring 

 and summer; fruit ripening in the fall. 



7. Vitis Berlandiferi Planch. A stocky vine, not extensively climbing. Leaf-blades 

 thinnish, suborbicular or ovate-orbicular in outline, 5-15 cm. broad, toothed, angidarly 

 3-lobed near the triangular apex, glabrous above in age, mostly sparingly pubescent on the 

 nerves and gray-nerved beneath, cordate at the base; petioles cottony, about p as long as 

 the blades: panicles 1-2 dm. long, compact: berries subglobose, 8-10 mm. in diameter, 

 purple, slightly glaucous, juicy and i)leasant-tasted : seeds pear-shaped, often broadly so, 

 4-5 mm. long, each with a conspicuous raphe, frequently solitary. 



On limestone hills, Texas and adjacent Mexico. Spring ; fruit ripening in September. 



8. Vitis vulpina L. A low bushy vine straggling over rocks and bushes, or high- 

 climbing. Leaf-blades thin, commonly longer than broad, 5-20 cm. broad, mostly sharply 

 3-lobed and coarsely and irregularly toothed, glabrate or pubescent on and about the 

 nerves beneath, cordate or nearly truncate at the base, the teeth and lobes acuminate ; 

 petioles \ as hmg as the blades or nearly equalling them in length, commonly with ample 

 stipules, glabrous or densely pubescent : panicles 6-20 cm. long, often much branched :
