 20. Girdiana, :\lnnsoii. Valley Orape. Strong, climb- 

 ing vine, with thick (Uni'liragras: lvs. medium to large and 

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

 narrow sinus and nearly continuous or obscurely 8-lobed 

 outline (sometimes luarkedly 3-lobed on young sboots),

Vitis bicolor ( X 



the teeth many ami stnall and acute, the apex short- 

 triangular or almost none, the under surface remaining 

 closely ashy-tomeutose : clusters large and very com- 

 pound, each one dividing into three or four nearly equal 

 sections, which are in turn shouhlered and thyrse-!ike: 

 berries small, black and slightly glaucous, the skin thin 

 but tough, pulp finally becoming sweet: seeds medium 

 in size, pyrifonn. S. Calif., south of the 8ljth parallel. 

 — Differs from T. Califorvica, in the more pubescent 

 shoots and foliage, smaller and sharp teeth, decompound 

 clusters, smalh-r less glaucous >)erries, and smalh-r 

 seeds. Shoots of (', Californica often bear Its. with 

 small and muticous teeth, and such specimens without 

 tlie rt. -clusters are difficult to distinguish from tliis 

 species. Some of the forms which have been referred 

 to r. Girdiana. are apparently hybrids with the wiTie 

 Grape, T. viuifera: and at best the plant is imperfectly 

 understood and its merits as a species are yet to be 

 determined. 



21. Doani^na, Mnnson. Plant vigorous, climbing 

 liigli or remaii]ing bushy if failing to find support, witli 

 siiort internodes and rather thin diaphragms: lvs. blu- 

 ish green in cast, mostly large, thick and firm, cordate- 

 ovate or round-ovate in outline, bearing a prominent 

 triangular apex, the sinus either deep or shallow, the 

 margins with very large, angular, notch-like teeth and 

 more or less prominent lobes, the under surface usually 

 remaining densely pubescent and the upper surface 

 more or less floccose: cluster medium to small, bearing 



large {% in. and less in diam.), black, glaucous berries 

 of excellent quality : seeds large {^'•^-% 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 gUi- 

 brous at maturity and others densely white-tomento.'-e. 

 The plant would pass at once as a hybrid of I", rnlpiua 

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

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

 and r. candica}is seems to be one of the parents. 



Busty -tipped Grapes, comprising the a^stiraHon 

 group, the unfolding lvs. a)id (except in V. bi- 

 color) the young shoots distinctly ferrugineou.s, 

 and the mature lvs. either rusty or bluish below, 

 or so)netimes becoming green in V. bicolor.

 Americana , Bartram. F. Nortoni, Prince. \\ Lu- 

 briisca, var. cestivdlis, Regel. V. bractedla- and 

 r. araneosus, LeConte). Summee, Bunoh, or 

 Pigeon Grape. Strong, tall-climbing vine, w ilh 

 medium short internodes, thick diaphragms, 

 and often pubescent petioles: lvs. mostly large, 

 thinnish at first but becoming rather thii-k, 

 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 briia<lly and often olttuseiy 

 triangular, the upper surface dull and becom- 

 ing glabrous and the under surface retaining 

 a covering of copious rusty or red-brown pu- 

 bescence wdiich 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 ( ^a 

 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 (/4 in. or less long), two to four. South- 

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

 sissippi and Missouri.— A marked tj'pe among American 

 Grapes, being readily distinguished from other species 

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



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

 Mnnson). 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, hut lvs. thicker and more pubescent below, and 

 tips of shoots rnsty-tomentose. 



Var. Linsecomii, Mnnson ( V. diversifdlia ^ Prince. 

 T'. Ifinsecomii, Buckley). Post-oak, Pine-wood, or 

 Turkey Grape. More stocky than V. aestivalis, climb- 

 ing high upon trees but forming a bushy clump when 

 not finding support: lvs. densely tomentose or velvety 

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

 glaucous, mostly palatable: seeds mostly much larger 

 than in I', (rstiralls (often %m. long). High post-oak 

 {Querrus stcllata] lands, S. W. Missouri to N. Texas 

 ajid E. La. — Very likely derived from the (xstivalis type 

 through ada])tation to dry soils and climates. Perliajts 

 worth recognition as a geographical species. The name 

 of this <.Trape was spelled Linsecomii by Buckley, with 

 whom the name originated. The name of the person 

 whom he commemorated was spelled Lincecnni, and 

 Mnnson lias therefore change<l the sx'clling of the name 

 of the Grape. However, Buckley's spelling should i^er- 

 sist, as a matter of nomenclatorial priority. 



Var. Bourquiniana, Bailey ( V. Bonrq-uinieina , Mnn- 

 son). A domcstie ofl'shoot, represented in such culti- 

 vated varieties as Herbemont and Ije Noir, differing 

 from r. cpsiirulis 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. a'stiv- 

 rr?/.s,and some hybridized with the wine Grape ( V. vini- 

 fera). Much cultivated south.
