"Coal mine in Coal Bluff, Herendeen Bay, Alaska Peninsula (original No. 31); collected by W. W. Atwood and H. M. Eakin in 1908 (lot 5185)."
Description
From Hollick (1930) (p.99)
"Leaf of unknown dimensions, curved and narrowed above to a slender tip; margin serrate-denticulate below, undulate above; nervation pinnate, camptocraspedodrome; midrib curved; secondaries curved upward, merging at their extremities into connecting tertiary nerves with fine nervilles extending to and terminating in the teeth and undulations of the
margin."
From Hollick (1930) (p.99)
"This species is so closely similar to Celastrus curvinervis Ward (1886; 1887) (p. 555, pl. 53, figs. 9, 10; p. 82, pl. 36, figs. 3, 4) from the Fort Union formation of Montana, that I was at first inclined to regard them as identical. The only apparent difference between them is that in Ward's species the teeth are indicated as coarser and somewhat more serrate than in ours. He figures, however, two quite different forms under the same specific name, and his Figure 4 may be excluded if his Figure 3, with which our specimen may be compared, is to be taken as the type of the species.
Another leaf with which an interesting comparison may be made is Fraxinus johnstrupi Heer (1883) (p. 113, pl. 80, figs. 1 - 3) from the Tertiary beds of Greenland, which resembles ours as closely as the species previously mentioned. The specimens, however, are too fragmentary for satisfactory comparison."
