114 THE EVOLUTION OF OUR NATIVE FRUITS 



leaves densely tomentose or velvety below: berries large 

 (%- to %-inch in diameter), black and glaucous, mostly 

 palatable ; seeds mostly much larger than in Y. aestivalis 

 (often %-inch long). — High post-oak {Querents steUatd) Lands, 

 S. W. Missouri to N. Texas and E. Louisiana. Very likely 

 derived from the aestivalis type through adaptation to dry 

 soils and climates. Perhaps worth recognition as a geo- 

 graphical species. Of great promise to the cultivator. 

 Far. Bourquiniana, Bailey. A domestic offshoot, represented 

 in such cultivated varieties as Herbemont and Le Noir, dif- 

 fering from V. aestivalis in its mostly thinner leaves, which 

 (like the young shoots) are only slightly red-brown below, 

 the pubescence mostly cinereous or dun-colored or the under 

 surface sometimes blue-green: berries large and juicy, black 

 or amber-colored. — A mixed type, some of it probably a 

 direct amelioration of V. aestivalis, and some hybridized with 

 the wine-grape ( V. vinifera). Much cultivated South, and 

 the parent of many excellent varieties (see page 81 I, which 

 Munson (Texas Farm and Ranch, Feb. 8, 189G) arranges in 

 two sections, — the Herbemonts and the Devereuxs. 



J'itis bicolor, LeConte. (Blue Grape, or Summer Grape of the 

 North.) A strong, high -climbing vine, with mostly Long 

 internodes and thick diaphragms, the young growth and 

 canes generally perfectly glabrous and mostly (but not 

 always) glaucous-blue, tendrils and petioles very Long: 

 Leaves large, round- cordate -ovate in outline, glabrous and 



dull above and very heavily glaucous-blue below, but l08ing 



the bloom and becoming dull green very Late in the Beason, 

 those on the young growth deeply 3-5-lobed, and on the 

 older growths ahallowly 3-lobed, the basal sinus running 

 from deep to shallow, tlie margin s mostly shallow-toothed 

 or sinuate -toothed (at least not so prominently notch-toothed 



as in J', aestivalis)', olustei mostly Long and nearly simple 



i sometimes forked), generally with a long or prominenl 

 peduncle; the purple and densely glaucous berries of me- 

 dium si/.e t ' ._. - i 1 1 < ■ 1 1 or less in diameter), sour but pleasant- 

 tasted when ripe (just before I eds rather small. — 



Abundant nort liwaids along streams and OD banks, there 



taking the place of V. astivalis. B
