"Populus elliptica Newberry, Lyceum Nat. Hist. New York Annals, vol. 9, p. 16, 1868; The later extinct floras of North America: U. S. Geol. Survey Mon. 35, p. 43, pl. 3, figs. 1, 2, 1898." (Newberry 1868; 1898)

 

Remarks

From Hollick (1930) (p. 63)

"This specimen is apparently merely a small form of the species from the Dakota sandstone of Nebraska described by Newberry, although it may also be compared with the orbicular forms of Populus cyclomorpha Knowlton and Cockerell (1919) (p. 487 [= Populus rotundifolia Newberry, U. S. Nat. Mus. Proc., vol. 5, p. 506, 1882 [1883] The later extinct floras of North America: U. S. Geol. Survey Mon. 35, p. 51, pl. 29, figs. 1-4, 1898. Not Populus rotundifolia Griffith, 1847)) from the Eocene of the western United States, in regard to which Newberry (1882 [1883]) (p. 52) remarks:

"They present, however, a marked resemblance to those [poplars] described and figured in this report under the names of P. elliptica and P. flabellum, one from the Dakota group of Kansas, the other from the Upper Cretaceous of Orcas Island on the northwest coast, and P. cuneata from the TonguevRiver Tertiary."

Populus elliptica has not been heretofore recorded from elsewhere than the type locality in Nebraska."
