Locality
From Hollick (1930) (p. 104)
"Yukon River, north bank, about 5 miles above Louden station [Nahochatilton] (original No. 22); collected by W. W. Atwood and H. M. Eakin in 1907 (lot 4635)."
Description
From Hollick (1930) (p. 104)
"Leaf small, 2 centimeters in length by 2.5 centimeters in maximum width, asymmetric, with an oblique, truncate base, rounded on one side, bilobate on the other with one minor and one major lobe, the latter bilobed on the under side; margin crenate-dentate; midrib curved and turned to the rounded side of the leaf; nervation craspedodrome, consisting of the midrib, a single lateral primary extending from the base of the leaf to the apex of the major lobe with branches on the under and upper sides, a basal secondary nerve, and two pairs of opposite secondaries above."
Remarks
From Hollick (1930) (p. 104)
"This perfectly preserved and well-defined specimen evidently represents a leaf normally asymmetric - not one in which the asymmetry is due to distortion, as might be inferred from a superficial glance at the figure."
