Locality
From Hollick (1930) (p. 92)
"Yukon River, south bank, about 3 miles below Seventymile Creek (original No. 3AH4), collected by Arthur Hollick and Sidney Paige in 1903 (lot 3243)."
Description
From Hollick (1930) (p. 92)
"Plate 62, Figures 3, 4; Plate 73, Figure 1"
"Leaves ovate or oval, 9 to 10 centimeters in length by 8 to 8.5 centimeters in width, peltate at a distance of about 4 millimeters from the somewhat asymmetric base; margin irregularly triangular-dentate and crenate-dentate; nervation craspedodrome, pinnate subpalmate; midrib normally straight; secondary nerves five on each side, opposite or subopposite, subparallel, leaving the midrib at angles of about 30°, all of approximately equal rank, the lowest pair suprabasilar, simulating lateral primaries, with four or five
branches on the under sides that curve upward, the lower ones forked; basilar veinlets horizontal from the sides of the midrib and radiating downward from base."
Remarks
From Hollick (1930) (p. 92)
"This appears to be a distinct species, more symmetrical than the others in the genus, with straighter more uniform nervation and a shorter peltate base. The fragmentary specimens represented by Figures 3 and 4 on Plate 62 are included with some doubt. Their general characters, however, appear to agree with those of the more perfect specimen, and they are all included in collections made in the same general locality."
