From Hollick (1930) (p. 81-82)

"There does not appear to be any marked distinction between our specimen from Alaska and Lesquereux's figure of this species from the Dakota sandstone of Kansas, although our specimen is imperfect in its upper part, where the perfect leaf might show some character that would serve to differentiate it, and hence the identification is questioned. In many respects it is strikingly similar to the Tertiary lauraceous species Laurus grandis Lesquereux (1883) (p. 251, pl. 58, figs. 1, 3) especially in the expanded upper part of the leaf, which is decidedly broader than in Persea hayana; and in any collection of Tertiary plants our specimen would probably be referred to the former species. In this connection it is also significant that our specimen is one of a mixed collection in which Tertiary plants (including a "Laurus? sp.") were identified by Knowlton (1911) (p. 57. See also this paper, p. 5)."
