110 THE EVOLUTION OF OUR NATIVE FRUITS 



uous or very indistinctly 3-lobed (or sometimes prominently 

 lobed on youiig growths^ the leaves and shoots white -woolly 

 when young, but becoming nearly glabrous with age : sta- 

 mens ascending in sterile flowers and recurved in the fertile 

 ones: bunches small and compound, not greatly, if at all, 

 exceeding the leaves, bearing 20 to 40 small black berries 

 of pleasant taste; seeds 2 to 3, medium size. Along river 

 banks, W. Texas to New Mexico and Arizona, mostly south 

 of the 35th parallel, to S. E. California and N. Mexico. Not 

 promising horticulturally 



Far. glabra, Munson. Plant glabrous, with glossy and mostly 

 thinner and larger leaves. In mountain gulches and canons, 

 with the species and ranging northwards into S. Utah. 

 Readily distinguished from F. monticola by its triangular- 

 pointed and small-toothed leaves. 



BBB. Orbicular- scallop -leaved species of the Pacific Coast. 

 Vitis Californica, Benth. Vigorous species, tall-climbing upon trees 

 (Fig. 19), but making bushy clumps when not finding support, 

 the nodes large and diaphragms rather thin: leaves 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 

 remaining plainly pubescent below, the sinus ranging from 

 very narrow and deep to broad and open, the margins vary- 

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

 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 long-peduncled and 

 forked, the numerous small berries glaucous -white, seedy 

 and dry but of fair flavor; seed large (%- to T Vinch long), 

 prominently pyriform. Along streams in central and N. Cal- 

 ifornia and S. Oregon. Leaves becoming handsomely colored 

 aud mottled in fall. Of small promise horticulturally. 



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

 foliage, the leaves prominently rusty or white -tomentose or 

 glaucous-blue below. V. cinerea, V. Arisomca, and possibly 

 V. Californica may be sought here; and late -gathered forms 

 of F. bicolor may be looked for in A.
