          Vitis vulpina (Vitis reparia michx)

Sample Taken 7/8/42
Studied 7/11/42

All leaves thin.  Mature leaf almost completely glabrous on
under side but with tufting of pubescence and of setaceous hairs at
the axils of the veins -- prominent.  Some semi setaceous hairs along
veins but not very abundant.  Condition of the petiole like that of the
veins.

Upper surface glabrous but showing some very fine short setaceous
hairs along veins

Young growing tip completely glabrous but petioles of young leaves
show some setaceous hairs.  The tufting of these at the axils of the veins
is prominent and distinctive.  A few bristles occur on branchlets

The upper surface of the youngest leaves shows few very fine
wooly strands.  Setaceous hairs on veins of young leaves on upper
surface.

Thin leaves and a general glabrous appearance seem to
separate this species from all others so far examined
