Sample Taken 7/6/42
Studied 7/7/42

Mature leaves almost completely glabrous underneath -- just
a mere scanty cobweb pubescence.  Same applies to the
petiole and ribs

Young tips of vine also nearly glabrous but the small leaves
show considerable white pubescence.  It looks as though the
pubescence is present in the young leaves and this same
is thinned out as the leaf grows without any or little reverse in
amount

Upper surface of leaf nearly completely glabrous -- an
occasional cobwebby hair only showing.  The condition of
the upper surface of the young leaves shows the same relationship
to pubescence as in the case of the under side -- that is the
cobwebby hairs while these are more abundant than on the
mature leaf.

Petioles and veins show no stiff setaceous hairs.

No tufts or masses of pubescence or bristles in
the axils of the veins.
