VITIS 



the under sides of the Ivs. : cluster longer-peduncled and 

 more compound. Manatee Co., Fla.; and apparently 

 also in Ark.; possibly a compound with V. sestivalis, 

 but the Ivs. have the characteristic shape of V. cinerea. 

 Not to be confounded with any form of V. caribsea, 

 because of the lobed triangular-topped Ivs. and much 

 larger teeth. 



Var. canescens, Bailey. A form with rounded or 

 heart-like Ivs., the upper half of the If. lacking the 

 triangular and 3-lobed shape of the type. St. Louis, 

 Mo., and S. 111. to Texas. 



22. arizfinica, Engelm. (V. arizonensis, Parry). 

 CANON GRAPE. Plant weak, much branched, with short 

 internodes and thick diaphragms, branchlets angled: 

 Ivs. mostly small, cordate-ovate and with a prominent 

 triangular-pointed apex, the sinus broad or the base of 

 the blade even truncate, the teeth many and small and 

 pointed or mucronate, the margin either continuous or 

 very indistinctly 3-lobed (or sometimes prominently 

 lobed on young growths), the Ivs. and shoots white- 

 woolly when young, but becoming nearly glabrous 

 with age: stamens ascending in sterile fls. and recurved 

 in the fertile ones: bunches small and compound, not 

 greatly, if at all, exceeding the Ivs., bearing 20-40 

 small black berries of pleasant taste; seeds 2-3, medium 

 size. Along river banks, W. Texas to New Mex. and 

 Ariz., mostly south of the 35th parallel, to S. E. Calif, 

 and N. Mex. 



Var. glabra, Munson. Plant glabrous, with glossy 

 and mostly thinner and larger Ivs. In mountain gulches, 

 with" the species and ranging northward into S. Utah. 

 Distinguished from V. monticola by its triangular- 

 pointed and small-toothed Ivs. Perhaps a form of V. 

 Treleasii. 



23. calif6rnica, Benth. Fig. 3962. A vigorous spe- 

 cies, tall-climbing on trees but making bushy clumps 

 when not finding support, the nodes large and dia- 

 phragms rather thin: Ivs. mostly round-reniform (the 

 broader ones the shape of a horse's hoof -print), rather 

 thin, either glabrous and glossy or (more commonly) 

 cottony-canescent until half grown and usually remain- 

 ing plainly pubescent below, the sinus ranging from 

 very narrow and deep to broad and open, the margins 

 varying (on the same vine) from finely blunt-toothed to 

 coarsely scallop-toothed (the latter a characteristic 

 feature), the upper portion of the blade either per- 

 fectly continuous and rounded or sometimes indis- 

 tinctly 3-lobed and terminating in a very short apex: 

 bunches medium, mostly long-peduncled and forked, 



the numerous small berries glaucous-white, seedy and 

 dry but of fair flavor; seed large (^-j^in. long), 

 prominently pyriform. Along streams in Cent, and N. 

 Calif, and S. Ore. Lvs. becoming handsomely colored 

 and mottled in autumn. Very susceptible to mildew.

24. Girdiana, Munson. VALLEY GRAPE. SOUTHERN 

 CALIFORNIA GRAPE. Strong climbing 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 out- 

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

 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 3 or 4 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. 

 Differs from V. californica in the more pubescent 

 shoots and foliage, smaller and sharp teeth, decom- 

 pound clusters, smaller less glau- 

 cous berries, and smaller seeds, 

 Shoots of V. californica often 

 bear Ivs. with small and muti- 

 cous teeth, and such specimens 

 without the fl.-clusters are dif- 

 ficult to distinguish from this 

 species. Some of the forms 

 which have been referred to V. 

 Girdiana are apparently hybrids 

 with the wine grape, V. vinifera; 

 the plant is imperfectly under- 

 stood and its merits as a species 



are yet to be determined. It bears the name of H. H. 

 Gird, of Calif. 



25. Doaniana, Munson. Plant vigorous, climbing 

 high or remaining bushy if failing to find support, with 

 short internodes and rather thin diaphragms: Ivs. 

 bluish green in cast, mostly large, thick, and firm, cor- 

 date-ovate or round-ovate in outline, bearing a promi- 

 nent 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,
