          Vitis berlandieri

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

Under surface of mature leaf shows only very scanty very 
fine cobwebby pubescence with small setaceous hair generally distributed
over intervein spaces on the small branchlets of veins, though more concentrated
along main veins on ribs.  Slight tufting at axils of the veins but not
prominently so.  Reddish petiole densely setacious the hairs being very fine

Upper surface of the mature leaf shows a few fine pubescent strands--
particularly along the veins.  Fine setaceous hairs line the veins.

Young growing tip of cane wooly pubescent with this rough
hairiness extending up the petioles which show beneath very abundant
very fine setaceous hairs.  The petiole of the under side of the small leaves
is just about like that of the mature leaves though the brownish wooly
pubescence is a bit more marked along the veins of the smallest leaves

Fine hairiness on upper surface of young leaves is more marked than on under side
but this is not heavy.  Setaceous hairs occur along the veins in all
but the tip most small leaves

Tendril almost rudimentary single-forked in this specimen
