Glyptostrobus europaeus (BRONGNIART) UNGER

Brown (1962) used the name Glyptostrobus nordenskioldii (HEER) R. W. BROWN , based on similarity to original material from the Paleogene of Spitsbergen (recently reanalyzed by Budantesev and Golovneva 2009). Hickey (1977) argued that there were insufficient foliage and cone characters to distinguish the North American fossil Glyptostrobus species from that of Europe, and that the name Glyptostrobus europaeus (BRONGNIART) HEER should be applied both to North American and European material. LePage (2007) observed that this combination was actually published earlier by Unger (1850), and so should be cited as Glyptostrobus europaeus (BRONGNIART) UNGER. LePage (2007) reported that more than 30 binomials have appeared in the literature on fossil occurrences of Glyptostrobus around the Northern Hemisphere ranging from Cretaceous to Pliocene, most of which appear indistinguishable based on their diagnoses and stressed that there is need for more detailed comparative work among them.

Taxodium olrikii (HEER) R. W. BROWN was reported from the Rocky Mountain and Great Plains region based on leaves, but no confirming seeds or cone fragments have been recognized so the identification of Taxodium remains unconfirmed. This species was originally recognized from the Paleocene of Greenland, and then from Spitsbergen, but convincing reproductive material remains to be documented ( Budantsev and Golovneva 2009).
