Locality
From Hollick (1930) (p 89)
"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 89)
"Leaf about 13 centimeters in length by 14 centimeters in maximum width, with an obovate outline and a broad, wavy, entire, truncate base; nervation pinnate subpalmate; midrib flexuous, turned to one side in the upper part; secondary nerves alternate, five or
more on each side, flexuous, the upper ones leaving the midrib at angles of about 45°, the lowest two subopposite, suprabasilar, simulating lateral primaries, diverging from the midrib at angles of about 60°, curving upward, with six or more slender branches on the under sides that curve upward and coalesce in a network of fine nervilles along the margin; basilar veinlets arched upward and ultimately bent downward to the margin."
Remarks
From Hollick (1930) (p 89)
"This leaf appears to be intermediate in form between the larger and the smaller species of Credneria described in this volume. The margin is apparently entire in its lower part, and the general appearance of the leaf indicates that it was expanded and asymmetric
in its upper part."
This leaf base appears to be peltate.
