From Hollick (1930) (p. 51-52)

"Although our specimens are somewhat fragmentary, there can be but little doubt that they are referable to this more or less variable species. Under the name Thinnfeldia lesquereuxiana Heer (1882) (p. 37, pl. 44, figs. 9, 10; pl. 46, figs. 1 - 11, 12a, b) it is represented in the Atane beds of Greenland and the Raritan formation of New Jersey (Newberry 1895 [1896]) (p. 59, pl. 11, figs. 1 - 17); and under the name Protophyllocladus subintegrifolius it is reported by Berry (1916) (p. 796) from the Upper Cretaceous of Maryland, the Tuscaloosa formation of Alabama, and the Magothy formation of New Jersey (Berry 1904) (p. 69, pl. 1, fig. 5) and by Hollick from what is probably an equivalent horizon on Staten Island, N. Y., Block Island, R. I., and Marthas Vineyard, Mass. (Hollick 1906) (p. 36, pl. 5, figs. 1 - 6).

The specimens from Kansas figured by Lesquereux in his "Flora of the Dakota group" are noiIceably larger than any of the other American specimens referred to the species and are more or less suggestive of Protophyllocladus polymorphus (Lesquereux) Berry, the species last described; and Kryshtofovich (1918) (p. 41, text fig. 6 on p. 42) has figured a similar specimen from the Cretaceous of the island of Sakhalin, under the name P. subintegrifolius, that might about equally well be referred to P. polymorphus. If correctly represented in the
figure however the nervation is hardly that of Protophyllocladus."
