Locality
From Hollick (1930) (p. 107)
"Yukon River, north bank, about 12 miles below Melozi telegraph station (original No. 3AH11); collected by Arthur Hollick and Sidney Paige in 1903 (lot 3248)."
Description
From Hollick (1930) (p. 107)
"Leaf rhomboid-ovate, about 18 centimeters in length by about 18 centimeters in width across the middle, obscurely trilobate, tapering to the acuminate apex, rounded and narrowed to the base; margin remotely and finely undulate-dentate above, undulate and entire below; nervation pinnate subpalmate; secondary nerves simple, opposite below, alternate above, craspedodrome, leaving the midrib at obtuse angles of divergence, soon bending and curving upward, lowest two simulating lateral primaries, each with simple, upward-curved branches on the under side that extend to and thin out along the margin, and a forking branch on the upper side toward the extremity."
Remarks
From Hollick (1930) (p. 107)
"This species is analogous to the general type of leaf represented by Grewiopsis acuminata Lesquereux (1887) (p. 44, pl. 3, figs. 12, 13) and G. walcotti Lesquereux (1887) (p. 45, pl. 4, figs. 1, 2) from the so-called "Laramie" formation of Utah. Our specimen agrees essentially with these species in form, nervation, and marginal characters, and but for its much larger size might almost be regarded as a form or variety of the species last named."
