VITIS 



VITIS 



34S9 



bearing large (%in. and less diam.), black, glaucous 

 berries of excellent quality; seeds large (J^-jJ-'gin. long), 

 distinctly pyriform. Chiefly in X. W. Texas, but 

 ranging from Greer Co., Okla., to beyond the Pecos 

 River in New Mex. G.F. 9:455. The species varies 

 greatly in pubescence, 

 some specimens being 

 very nearly glabrous 

 at maturity and others 

 densely white-tomen- 

 tose. The plant would 

 pass as a hybrid of V. 

 vulpina and V. candi- 

 cans, except that these 

 species do not often 

 occur in its range. 

 It bears the name of 

 Judge J. Doan, of Wil- 

 barger Co., Texas. It- 

 gives promise as a pa- 

 rent of pomological 

 grapes. The Arnold 

 Arboretum reports it as 

 *'a fast-growing plant 

 and appears to be per- 

 fectly at home in New 

 England. The leaves 

 are large, thick and firm, and rather pale bluish green 

 in color. The fruit, which grows in small clusters, is 

 blue covered with a pale bloom and of fair quality." 



26. caribsea, DC. Fig. 3963. Climbing, with floccu- 

 lent-woolly (or rarely almost glabrous) and striate 

 shoots: tendrils rarely continuous: Ivs. cordate-ovate 

 or even broader and mostly acuminate-pointed, some- 

 times obscurely angled above (but never lobed except 

 now and then on young shoots), becoming glabrous 

 above but generally remaining rufous-tomentose below, 

 the margins set with very small, mucro-tipped sinuate 

 teeth: cluster long and long-peduncled, generally large 

 and very compound: berry small and globose, purple; 

 seed obovate. grooved on the dorsal side. A widely dis- 

 tributed and variable species in the American tropics, 

 running into white-lvd. forms (as in V. Blaruxri, 

 Munson). Although supposed to occur from Fla. to 

 Texas, Munson is "unable to discover the slightest 

 traces of this species in the U. S..;" he considers the 



3963. Vitis caribasa. 



3964. Vitis bicolor. ( X H) 



Fla. plants to be hybrids of other species, or forms of 

 F. cinerea. The species is considered to be promising 

 for the development of a pomological grape for the 

 tropics (F. S. Earle, Journ. Heredity, Dec., 1915). 

 V. ruf otomentdsa, Small, differs in having the If .-blades 

 usually distinctly lobed and the margins coarsely 

 toothed, rusty -tomentose on nerves beneath: sandy 

 soil, Fla to La. 



27. bicolor, Le Conte (V. argentifdlia, Munson). 

 BLUE GRAPE, or SUMMER GRAPE of the N. Fig. 3964. 

 A strong high-cUmbing vine, with mostly long inter- 

 nodes and thick diaphragms, the young growth and 

 canes generally perfectly glabrous and mostly (but not 

 always) glaucous-blue: tendrils and petioles very long: 

 Ivs. large, round-cordate-oyate in outline, glabrous and 

 dull above and very heavily glaucous-blue below, but 

 losing the bloom and becoming dull green very late in 

 the season, those on the young growth deeply 3-5- 

 lobed and on the older growths shallowly 3-lobed, the 

 basal sinus running from deep to shallow, the margins 

 mostly shallow-toothed or sinuate-toothed (at least 

 not so prominently notch-toothed as in F. xstivalis) : 

 cluster mostly long and nearly simple (sometimes 

 forked), generally with a long or prominent peduncle: 

 the purple and densely glaucous berries of medium size 

 (K- or less diam.), sour but pleasant-tasted when 

 ripe (just before frost) ; seeds rather small. Abundant 

 northward along streams and on banks, there taking 

 the place of F. aestivalis. Ranges from New England 

 and 111. to the mountains of W. N. C. and to W. Tenn. 

 Well distinguished from F. aestiralis (at least in its 

 northern forms) by the absence of rufous tomentum, 

 the blue-glaucous small-toothed Ivs. and long petioles 

 and tendrils. It has been misunderstood because it 

 loses its glaucous character in autumn; an excellent 

 species as a covering for arbors and trellises. 



28. aestivalis, Michx. (F. Nortoni, Prince. V. 

 Labrusca, var. sestirdlis, Regel. F. bracteata and F. 

 araneosus, Le Conte). SUMMER, BUNCH, or PIGEOX 

 GRAPE. Strong tall-climbing vine, with medium short 

 internodes, thick diaphragms, and often pubescent 

 petioles: Ivs. mostly large, tninnish at first but becoming 

 rather thick, ovate-cordate to round-cordate in outline, 

 the sinus either deep (the basal lobes often overlapping) 

 or broad and open, the limb always lobed or prominently 

 angled, the lobes either 3 or 5, in the latter case the 



lobal sinuses usually enlarged and rounded 

 at the extremity, the apex of the If. broadly 

 and often obtusely triangular, the upper sur- 

 face dull and becoming glabrous and the 

 under surface retaining a covering of copious 

 rusty or red-brown pubescence which clings 

 to the veins and draws together in many 

 small, tufty masses: stamens in fertile fls. 

 reflexed and laterally bent: clusters mostly 

 long and long-peduncled, not greatly branched 

 or even nearly simple (mostly interrupted 

 when in flower), bearing small (Hin. or less 

 diam.), black, glaucous berries, which have 

 a tough skin and a pulp ranging from dryish 

 and astringent to juicy and sweet; seeds 2-4, 

 medium size (M m - or I 688 l n g)- S. N. Y. to 

 Cent. Fla. and westward to the Mississippi 

 and Missouri rivers. A marked type readily 

 distinguished from other species by the red- 

 dish fuzz of the under side of the Ivs. 

 Var. Bourquiniana, Bailey (F. Bourquiniana, Mun- 

 son). A domestic offshoot, represented in such cult, 

 varieties as Herbemont and Le Noir, differing from F. 

 sfstivalis in its mostly thinner Ivs. which (like the young 

 shoots) are only slightly red-brown below, the pubes- 

 cence mostly cinerous or dun-colored or the under sur- 

 face sometimes blue-green: berries large and juicy, 

 black or amber-colored. A mixed type, much cult 

 S. It is probably exotic, but may have been modified
