Locality
From Hollick (1930) (p. 89)
"Yukon River, north bank, about 8 miles below Kaltag (original No. 3AH29); collected by Arthur Hollick and Sidney Paige in 1903 (lot 3268)."
Description
From Hollick (1930) (p. 88-89)
"Leaf medium sized, of unknown shape, with a sub-cordate, truncate base and irregularly, coarsely serrate-dentate margin; midrib strong, with an abruptly enlarged base from the lower pair of secondary nerves downward; secondary nerves strong, irregularly disposed, leaving the midrib at acute angles of divergence, the lower pair subopposite, suprabasilar, each with three or more branches from the under side, all curving upward; basilar nervilles well defined, branched, the branches terminating in the teeth."
Remarks
From Hollick (1930) (p. 88-89)
"This beautiful leaf evidently represents a distinct species, and it is unfortunate that only the lower part is preserved. It is especially characterized by its broadly expanded base traversed by conspicuous nervilles. Also, the secondary nerves are more widely, spaced and dentitions larger than in any other species."
