Locality
From Hollick (1930) (p. 89-90)
"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. 89-90)
"Leaf small, obovate(?), approximately 2.5 centimeters in length by 1.75 centimeters in maximum width, terminating below in a cuneate, decurrent base; nervation subtripalmate; lateral primaries opposite, suprabasilar at a distance of about 4 millimeters above the base, sharply ascending at acute angles of divergence from the midrib, each with three or more subparallel ascending branches on the under or outer side; lower margin entire; basilar veinlets ascending, subparallel with the lower branches of the lateral primaries."
Remarks
From Hollick (1930) (p. 89-90)
"This imperfect little leaf, on account of its small size, is referred with some doubt to Credneria. The only other recognized species of the genus with which it compares in size is one depicted by Kryshtofovich (1918) (p. 52, fig. 9) under the name Credneria aff. integerrima Zenker (1833) (p. 17, pl. 2, fig. F) from the Cretaceous of the island of Sakhalin. The comparison with Zenker's species, however, refers only to similarity in shape, as may be seen by a glance at the two figures. It appears probable that a perfect leaf of our species would not be very different in character from the leaf figured by Kryshtofovich, although the indicated form of ours is narrower."
