          Vitis baileyana

Sample Taken 7/8/42  Beltsville
Studied 7/9/42

Under surface of mature leaf lightly wooly pubescent -- more
marked along veins.  Setaceous hairs extend along sides of veins
and out onto the swollen veinlets.  Intra vein areas clearly visible
stomata fairly prominent.  A little tufting of pubescence at 
axils of veins but this not prominent.

Petiole lightly wooly pubescent with rows of setacious hairs
upper surface of mature leaf nearly or entirely glabrous but
numerous short setaceous hairs are prominent on the veins

This condition not observed in any other species so far 
examined.

Growing point of young cane almost glabrous

Under surface of young leaves almost completely glabrous -- a few
very fine cobwebby hairs present.  The prominent feature is the 
heavy equipment of setaceous hairs on petioles and veins with
some tufting at axils

Upper surface of young leaves almost completely glabrous
but veins prominently equipped with short setaceous hairs.

tendrils very small but 2-pronged
