"Glyptostrobus gronlandicus Heer, Die Kreide-Flora der arctischen Zone: Flora fossilis arctica, vol. 3, No.2, p. 76, pl. 17, fig. 9; pl. 20, figs. 9, lOa; pl. 22, fig. 12, 1874." (Heer 1874)



From Hollick (1930) (p. 60)

"The heterophyllous character of this species is well exemplified in Heer's Figure 9 on Plate 20, and by our Figure 2 on Plate 26, which also includes an immature fruiting twig. The leaves of our specimens appear to be somewhat narrower throughout than in Heer's figures; but the differences between them are too insignificant to warrant anything more than a possible varietal distinction, in any event.

The species is also recorded by Dawson (1885 [1886]) (p. 9, pl. 3, fig. 8) from the Kootenai formation of the Canadian Rocky Mountain region, which is about the equivalent of the Kome beds of Greenland from which Heer's specimens were obtained."
