"Sequoia obovata Knowlton, Flora of the Fruitland and Kirtland formations: U. S. Geol. Survey Prof. Paper 98, p. 333, 1916; Geology and paleontology of the Raton Mesa and other regions in Colorado and New Mexico: U. S. Geol. Survey Prof. Paper 101, p. 250, pl. 30, fig. 7, 1917."

From Hollick (1930) (p. 58-59)

"These specimens are almost certainly referable to the Upper Cretaceous species to which Knowlton gave the above name in order to differentiate it, stratigraphically, from Sequoia brevifolia Heer (1868) (p. 93, pl. 2, fig. 23) from the Tertiary of Greenland, a species to which certain specimens from the western United States were referred by Lesquereux (1875 [1876]; 1878) (p. 365; p. 78, pl. 61, figs. 25 - 27). The two species resemble each other very closely, and it is questionable whether or not they arc specifically different: and the broader leaves of Sequoia obovata are also very diflicult to distinguish from Sequoia cuneata (Newberry) Newberry (1898) (p. 18, pl. 14, figs. 3-4a [= Taxodium cuneatum Newberry, Boston Jour. Nat. Hist., vol. 7, p. 511. 1863]) from the Upper Cretaceous of Vancouver Island.

Whatever the ultimate taxonomic determination of these three so-called species may be, there can be no question of the specific identity of our specimens with those figured by Knowlton from the Vermejo formation of southeastern Colorado under S. obovata and from the Montana group of Wyoming under S. brevifolia."
