with a prominent triangular-pointed apex, the sinus broad or the base of the blade even 

 truncate, tlie teeth many and small and pointed or mutrouate, the margin either continuous 

 or very indistinctly 3-lobed (or sometimes prominently lobed on young growths), the leaves 

 and shoots white-woolly when young, but becoming nearly glabrous with age : stamens 

 ascending in sterile flowers and recurved in the fertile ones: bunches small and compound, 

 not greatly, if at all, exceeding tiie leaves, bearing 20 to 40 small black berries of pleasant 

 taste ; seeds 2 to 3, medium size. — Am. Nat. ii. 321, ix. 268, & Eusbberg Cat. ed. 3, 16 ;

Var. glabra, Munson. Plant glabrous, with glossy and mostly thinner and larger 

 leaves. — Wild Grapes N. A. 10, Ganl. & For. iii. 474, & Am. Gard. xii. 660. — In mountain 

 gulches and caiions, with the species and ranging northwards into S. Utah. Readily distin- 

 guished from V. monticola by its triangular-pointed and small-toothed leaves. 

 ^— ^— H— Orbicular-scallop-leaved species of the Pacific Coast. 

 V. Californica, Bexth. A vigorous species, tall-climbing upon trees but making bushy 

 clumps when n(jt finding support, the nodes large and diaphragms ratlier tliin : leaves mostly 

 round-reniform (the broader ones the shape of a horse's hoof-print), ratlier thin, either gla- 

 brous and glossy or (more commonly) cottony-canescent until half grown and usually 

 remaining 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 coar.sely 

 scallop-toothed (the latter a characteristic feature), the upper portion of the blade either 

 perfectly continuous and rounded or sometimes indistinctly 3-lobed and terminating in a 

 very short apex : bunches medium, mostly loug-peduncled and forked, the numerous small 

 berries glaucous-white, seedy and dry but of fair flavor; seed large {\ to ^ inch long), 

 prominently pyriform. — Bot. Sulph. 10; Torr. Bot. Mex. Bound. 45; Buckley, Pat. Off.

* * Colored-leaved Grapes, marked by thick or at least firm foliage, the leaves promi- 

 nently rusty or white-tomentose or glaucous-blue below. V. ciitereu, V. Arizonica, and 

 possibly T'. Californica may be sought here ; and late-gathered forms of V. bicolor may be 

 looked for in *. 

 •i— Leaves only flocculent or cobwebby or glaucous below when fully grown (i. e., not covered 



with a thick dense felt-like tomentum, except sometimes in V. Doaniana). 

 ++ White-tipped grapes, comprising species with the ends of the growing shoots and the 

 under surfaces of the leaves whitish or gray. 

 V. Girdiana, Munson. (Valley Grape.) Strong climbing vine, with thick diaphragms: 

 leaves 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), 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 compound, 

 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. — Proc. Soc. Prom. Agr. Sci. 1887, 

 59, Wild Grapes N. A. 10, Gard. & For. iii. 474, & Am. Gard. xii. 660. — S. California, south 

 of tlie 36th parallel. Differs 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 leaves with small and muticous teeth, and such 

 specimens without the flower-clusters are difficult to distinguish from this species. Some
