From Hollick (1930) (p. 79-80)

"This leaf, though somewhat longer in relation to its width than the species to which it is referred, is otherwise so closely similar to that species that to regard it as distinct would seem hardly to be justified, especially as it is associated with other undoubted Dakota sandstone species in the collection from the same locality.

It is unfortunate that no complete specimen of the species has ever been figured. The type specimen lacks the apex, which, however, is described as "obtuse or abruptly pointed." Nevertheless, if we accept the several identifications of the species made by competent authorities it may be seen that they differ but little from one another. Newberry (1895[1896]) (p. 73, pl. 15, figs. 1, 2) figures two specimens from the Raritan formation of New Jersey, in one of which a lower portion only is shown, in the other an upper portion. The latter is apparently the only figure of the species extant in which the apex is shown, and whether or not the specimen actually belongs to this species may be regarded as open to question. I have figured two specimens from the Magothy formation of Marthas Vineyard, Mass. (Hollick 1906) (p. 65, pl. 17, figs. 1, 2) in which the lower parts only are shown. Berry (1916) (p. 832, pl. 70, figs. 1, 2) also figures two specimens, consisting only of lower portions, from the Magothy formation of Maryland; and the same author(Berry 1919) (p. 91, pl. 17, fig. 9) figures a specimen from the Tuscaloosa formation of Alabama, in which both base and apex are missing.

The areal distribution of the species is therefore quite extensive, embracing Alaska, Kansas, and the Atlantic Coastal Plain from Massachusetts to Alabama. It is not recorded from the Old World."
