"Plate 85, Figure 4a"

"Leaf pyramidal, 3 centimeters in length by 2 centimeters in width at a distance of about 6 millimeters above the base, tapering above to a wedge-shaped apex and rounded below to a broad, truncate base; margin triangular-serrate-dentate; nervation pinnate, craspedodrome; upper secondary nerves straight, parallel, opposite; lower two pairs subopposite; basal pair curved upward, with upward-curved branches on the under sides."



From Hollick (1930) (p. 69)

"This well-defined little leaf appears to be different from any heretofore described fossil species. It somewhat resembles the living Alnus rubra Bongard, of the Pacific coast, but the dentition is apparently simple. The base, while described as truncate, appears to be obscurely cordate."
