VITIS 



DD. Colored-leaved Grapes, marked by thick or at least 

 firm foliage, the Ivs. prominently runty or white- 

 tomentose or glaucous-blue. V. cinerea, V. Ari- 

 zonica, and possibly V. California might be sought 

 here; and late-gathered forms of V. bicolor might 

 be looked for in D (p. 1950). 



K. Lvs. only flocculent or cobwebby or glaucous below 

 when hilly grown (i. e., not covered with a thick, 

 dense, felt-like tomentum, except sometimes in V, 

 Doaniana). (Nos. 20-24:.} 



p. White-tipped Grapes, comprising species with the 

 ends of the growing shoots and the under surface 

 of the Ivs. whitish or gray. 



20. Girdiana, Munson. VALLEY GRAPE. Strong, climb- 

 ing vine,with thick diaphragms : Ivs. medium to large and 

 rather thin, broadly cordate-ovate, with a rather deep and 

 narrow sinus and nearly continuous or obscurely 3-lobed 

 outline (sometimes markedly 3-lobed on young shoots), 



2701. Vitis bicolor (X 



the teeth many and small and acute, the apex short- 

 triangular or almost none, the under surface remaining 

 closely ashy-tomentose: clusters large and very com- 

 pound, each one dividing into three or four nearly equal 

 sections, which are in turn shouldered and thyrse-like- 

 berries small, black and slightly glaucous, the skin thin 

 but tough, pulp finally becoming sweet: seeds medium 

 in size, pyriform. S. Calif., south of the 36th parallel. 

 -Difters from V. Californica in the more pubescent 

 shoots and foliage, smaller and sharp teeth, decompound 

 clusters, smaller less glaucous berries, and smaller 

 seeds. Shoots of V. Californica often bear Ivs. with 

 small and muticous teeth, and such specimens without 

 the fl. -clusters are difficult to distinguish from this 

 species. Some of the forms which have been referred 

 to V. Girdiana are apparently hybrids with the wine 

 tpe, V. vinifera; and at best the plant is imperfectly 

 understood and its merits as a species are yet to be 

 determined.

large (% in. and less in diarn.), black, glaucous berries 

 of excellent quality : seeds large (M-% in. long), dis- 

 tinctly pyriform. Chiefly in N. W. Texas, but ranging 

 from Greer Co., Oklahoma, to beyond the Pecos river in 

 New Mexico. G.F. 9:455. The species varies greatly 

 in pubescence, some specimens being very nearly gla- 

 brous at maturity and others densely white-tomentose. 

 The plant would pass at once as a hybrid of V. vulpina 

 and V. candicans, except that the former does not often 

 occur in its range. It is very likely a hybrid, however 

 and V. candicans seems to be one of the parents. 

 FF. Busty -tipped Grapes, comprising the cestivalian 

 group, the unfolding Ivs. and (except in V. bi- 

 color) the young shoots distinctly ferrugine'ous, 

 and the mature Ivs. either rusty or bluish below', 

 or sometimes becoming green in V. bicolor. 

 22. BBStivalis, Michx. ( V. sylvestris, occidentalis and 

 Americana, Bartram. V. Nortoni, Prince. F, La- 

 brusca, var. (estivalis, Regel. V. bracteata and 

 V. aranedsiis, LeCoute). SUMMER, BUNCH, or 

 PIGEON GRAPE. Strong, tall-climbing vine, with 

 medium short internodes, thick diaphragms, 

 and often pubescent petioles : Ivs. mostly large' 

 thinnish at first but becoming rather thick, 

 ovate-cordate to round-cordate in outline, the 

 sinus either deep (the basal lobes often over- 

 lapping) or broad and open, the limb always 

 lobed or prominently angled, the lobes either 

 3 or 5, in the latter case the lobal sinuses usu- 

 ally enlarged and rounded at the extremity, 

 the apex of the leaf broadly and often obtusely 

 triangular, the upper surface dull and becom- 

 ing glabrous and the under surface retaining 

 a covering of copious rusty or red -brown pu- 

 bescence which clings to the veins and draws 

 together in many small, tufty masses: stamens 

 in fertile fls. reflexed and laterally bent: clus- 

 ters mostly long and long- peduncled, not 

 greatly branched or even nearly simple (mostly 

 interrupted when in flower), bearing small (% 

 in. or less in diam.), black, glaucous berries, 

 which have a tough skin and a pulp ranging 

 from dryish and astringent to juicy and sweet: seeds 

 medium size (% in. or less long), two to four. South- 

 ern New York to central Fla. and westward to the Mis- 

 sissippi and Missouri. -A marked type among American 

 Grapes, being readily distinguished from other species 

 by the reddish fuzz of the under sides of the leaves. 



Var. glauca, Bailey ( V. Lincecumii, var. glaiica, 

 Munson). Lvs. and mature wood glaucous-blue on the 

 body beneath, but the veins rusty: berries and seeds 

 larger. S. W. Missouri to N. Texas. -Much like V. bi- 

 color,. but Ivs. thicker and more pubescent below, and 

 tips of shoots rusty-tomentose. 



Var. Linsecomii, Munson ( V. diversifblia . Prince 

 V. Linsecomii, Buckley). POST-OAK, PINE- WOOD or 

 TURKEY GRAPE. More stocky than V. cestivalis, climb- 

 ing high upon trees but forming a bushy clump when 

 not finding support: Ivs. densely tomentose or velvety 

 below: berries large (%-% in. in diameter), black and 

 glaucous, mostly palatable: seeds mostly much larger 

 than in V. cestivalis (often % in. long). High post-oak 

 (Quercus stellata) lands, S. W. Missouri to N. Texas 

 and E. La. -Very likely derived from the cestivalis type 

 through adaptation to dry soils and climates. Perhaps 

 worth recognition as a geographical species. The name 

 of this Grape was spelled Linsecomii by Buckley, with 

 whom the name originated. The name of the person 

 whom he commemorated was spelled Lincecum, and 

 Munson has therefore changed the spelling of the name 

 of the Grape. However, Buckley's spelling should per- 

 sist, as a matter of nomenclatorial priority. 



Var. Bourquiniana, Bailey ( V. Bourqidniana, Mun- 

 son). A domestic offshoot, represented in such culti- 

 vated varieties as Herbemont and Le Noir, differing 

 from V. (estivalis in its mostly thinner leaves which 

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

 below, the pubescence mostly cinerous 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. ce'stiv- 

 Zis,and some hybridized with the wine Grape ( V vini- 

 fera). Much cultivated south.
