          Vitis doaniana

Sample Taken 7/8/42
Studied 7/10/42

Under side of mature leaf shows a thin--very fine cobwebby
white mesh overlying long setaceous hairs that are numerous
on the veins and main branches and also the small branches.  Looks
almost as though tiny spiders had woven a web on these hairs.  The
white hairy pubescence is appressed along the veins.  There is not tufting
at axils of the veins either of setaceous hairs or pubescence

Petiole densely hairy -- white appressed except when disturbed by handling
upper surface of mature leaf thickly pubescent with very fine cobwebby
hairs -- pubescence more pronounced on the veins.  Some short
setaceous hairs seen on main veins of upper surface but these
not abundant

Young growing end of cane densely, white -- appressed hairy--
[note at side of page: very  [illegible]  ]
hairs extending longitudinally.  Same holds for petioles, & tendrils
Under surface of young leaves densely white felted in inter vein areas
but veins decidedly longitudinally whitish--hairy (like an old man looks)
a cottony-fairly heavy pubescence on upper surface of young
leaves -- becoming thinner as leaves expand

Stocky hairy 2-forked tendrils on this specimen
young growing tip stocky & heavy
