Sample taken  7/8/42
Studied             7/9/42

Under surface of mature leaf almost completely glabrous
but with many long setacious hairs along veins and
veinlets, tufted somewhat at axils of veins.  Under surface
epithelium clearly visible.  At[A] bit of cobwebby hairiness appears on
the petiole but sectaceous hairs make up most of the light roughness

Upper surface of mature leaf glabrous and generally free
from all setacious hairs even along main veins.

Young growing point of cane shows light hairiness
/very light hairy pubescence appears on under side of young leaves
but generally distributed setaceous hairs are found on the 
fine branches of the veinlets on the under side of fairly small
young leaves (1" - 2" diam

Upper surface of young leaves show very fine cobwebby hair
and setaceous hairs show to some extent along veins on upper
surface though not as marked as in Vitis baileyii
