of the forms which have been referred to V. Girdiana are evidently hybrids with the wine- 

 grape, V. vinifera; and at best the plant is imperfectly understood and its merits as a 

 species are yet to be determined. 

 V. Doaniana, Munson. Plant vigorous, climbing high or remaining bushy if failing to 

 find support, with short inter nodes and rather tliin diaphragms : leaves bluish 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 (f inch and less in diameter) black glaucous berries of excellent quality ; ' 

 seeds large (^ to | inch long), distinctly pyriform. — Wild Grapes N. A. 9, Gard. & For. 

 ill. 474, Am. Gard. xii. 660, & Rev. Vit. iii. 160 ; Viala & Ravaz, Vignes Am. 204 (considering 

 it a hybrid of V. candicans and the V. Longii group) ; Sears, Gard. & For. ix. 454, f. 59. — 

 Chiefly in N. W. Texas, but ranging from Greer Co., Oklahoma, to beyond the Pecos River 

 in New Mexico. The species varies greatly in pubescence, some specimens being very 

 nearly glabrous 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. 



++ ++ Rusty-tipped grapes, comprising the Eestivalian group, the unfolding leaves and 

 (except in V. bicolor) the young shoots distinctly ferrugineous, and the mature leaves 

 either rusty or bluish below, or sometimes becoming green in V. bicolor, 



V. aestivalis, Michx. (Summer, Bunch, or Pigeon Grape.) Strong tall-climbing vine, 

 with medium-short interuodes, thick diaphragms, and often pubescent petioles : leaves mostly 

 large, thinnish at first but becoming rather thick, ovate-cordate to round-cordate in out- 

 line, 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, tlie apex of the leaf broadly and 

 often obtusely triangular, the upper surface 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 flowers reflexed 

 and laterally bent : clusters mostly long and long-peduncled, not greatly branched or even 

 nearly simple (mostly interrupted when in flower), bearing small {\ inch or less in diameter) 

 black glaucous berries, which have a tough skin and a pulp ranging from dryisli and as- 

 tringent to juicy and sweet ; seeds medium size {\ inch or less long), two to four. — Fl. ii.

 V. araneosus, as if LeConte's type, but there is no proof that they are his type. These 

 specimens are V. cinerea, which is not known to occur in " the upper parts of Georgia," to 

 which V. araneosus is credited ; moreover, the " more or less ferruginous " leaves belong to 

 V. aestivalis rather than to V. cinerea.) — Chemung Co., New York {T. F. Lucy), and Long 

 Island to Central Florida {Nash, no. 525, Baileij), and westward through Southern Pennsyl- 

 vania to the Mississippi 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. 

 Most of the tomentose-leaved species have been at one time or another confounded with it, 

 but when allowed to stand by itself, it is not a difficult species to understand. 



Var. glauca, Bailey, n. comb. Leaves (and mature wood) glaucous-blue on the body 

 beneath, but the veins rusty: berries and seeds larger. — V. Li7icecu7nii, \av. gfatica, Munson, 

 Wild Grapes N. A. 12, Gard. & For. iii. 474, Am. Gard. xii. 585, & Rev. Vit. v. 159. — S. 

 W. Missouri to N. Texas. Much like V. bicolor, but leaves thicker and more pubescent 

 below, and tips of shoots rusty-tomentose.
