          Vitis cordifolia

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

Under surface of mature free of cobwebby or wooly
pubescence but veins are densely covered with setacious hairs
extending out onto finer branches

Petiole Setaceous--hairy

Upper surface of leaf glabrous but setaceous hairs line
the main vein surfaces as observed in Vitis baileyana.
(Vitis baileyana looks like an offshoot of Vitis cordifolia -- a bit
more slender as to young points with more acuminate leaves in
the case of Cordifolia as compared with Baileyana)

Young growing point of cane almost completely glabrous
with moderate amount of hairness on petioles and under surface
of young leaves   Setaceous hairs not prominent on under side
of young leaves

Very scant wooly hairness on upper side of young leaves with
some very fine setaceous hairs on main veins of young leaves

Tendrils single-forked
