Locality
From Hollick (1930) (p. 82)
"Yukon River, north bank, Fossil Bluff, about 6 miles above Nahochatilton (original No. 2AC238); collected by A. J. Collier and Sidney Paige in 1902 (lot 2962)."
Description
From Hollick (1930) (p. 82)
"Leaf spatulate-acuminate, entire, 7.5 centimeters in length by 2 centimeters in maximum width; secondary nerves irregularly pinnate in arrangement, mostly subopposite, leaving the midrib at acute angles of divergence below, at successively more and more obtuse angles above, curving upward and becoming camptodrome along the margin."
Remarks
From Hollick (1930) (p. 82)
"This is a well-defined species, apparently referable to Persea or some closely related lauraceous genus. Incidentally, however, it may be of interest to note its almost perfect resemblance to Rhus bella; Heer (1869) (p. 482, pl. 56, figs. 3 - 5) from a supposed Tertiary horizon in Greenland. If the leaf represented by Heer's Figure 4 had been described as a Cretaceous species the probability is that no question would have been raised as to its specific identity with ours from Alaska."
