"Yukon River, north bank, about 16 miles below mine No.1 (Original No. 40); collected by W. W. Atwood and H. M. Eakin in 1907 (lot 4643)."
Description
From Hollick (1930) (p. 110)
"Leaf trilobate, deeply divided, finely dentate, or denticulate, about 18 centimeters in length from base to summit of middle lobe; middle lobe longer and apparently broader than the laterals, about 4 centimeters in width near the middle, decreasing in width below and above; lateral lobes ascending, almost uniform in width, approximating 3 centimeters, slightly narrowed below and apparently tapering above; midrib and lateral primaries strong, about equal in rank; secondary nerves fine, ascending at acute angles of divergence from the primaries, curving upward toward the margin and throwing off slender nervilles that terminate in the dentitions."
From Hollick (1930) (p. 110)
"I was at first inclined to regard this specimen as a large form or variety of Aralia wellingtoniana Lesquereux, partly for the reason that it belongs in the same collection that includes the specimen last described and referred to that species. It differs, however, not only in size but more especially in the much finer and more numerous marginal denticulations. Both species evidently belong in the same group with Aralia saportana Lesquereux (1875 [1876]; 1883) (p. 394; p. 61, pl. 8, figs. 1 - 2; pl. 9, figs. 1 - 2)."
