Fossil Nymphaea pollen

Fossil Nymphaea pollen has not been reported from the Clarkia Lake deposits, but it is difficult to rule out the occurrence of Nymphaea in the Clarkia flora on this basis, because extensive palynological studies have not been carried out (cf. Smiley et al. 1975, Gray 1985). However, it should be noted that Nymphaea pollen has been described from other, coeval lake deposits from the Middle Miocene of the Pacific Northwest, namely at Succor Creek in Oregon and Palouse Falls in Washington state ( Dillhoff et al. 2014). Nymphaea water lilies were thus members of the aquatic macroflora of the freshwater lakes in the Pacific Northwest during the Miocene Climatic Optimum.
