Locality
From Hollick (1930) (p. 104)
"Yukon River, north bank, about 17 miles above Nahochatilton (original No. 2AC236); collected by A. J. Collier and Sidney Paige in 1902 (lot 2963)."
Description
From Hollick (1930) (p. 104)
"Leaf 13 centimeters in length by 18 centimeters in width across the expanded lower part, broadly ovate-reniform somewhat asymmetric, obscurely trilobate, rounded below to a broad, curved, truncate, subcordate base, and tapering above to an acuminate apex; margin irregularly and acutely triangular-dentate; midrib curved or bent to one side; nervation craspedodrome, subtripalmate; secondary nerves irregularly disposed, the upper ones alternate, leaving the midrib at angles of approximately 45°, branched toward the extremities, the main nerves and their branches each terminating in one of the teeth; lower two on each side opposite, the basilar pair simulating lateral primaries, slightly suprabasilar, spreading, each with about six almost horizontal branches on the under side and two or three on the upper side."
Remarks
From Hollick (1930) (p. 104)
"The general appearance of this leaf suggests the genus Platanus, but the curvature of the midrib and the arrangement of the secondary nerves on each side indicate that it is asymmetric, with one side (the left in our specimen) broader and more rounded than the other, as in many other species of Vitis."
