This is a generic-level assessment of taxa based on specimens in John Day Fossil Beds National Monument collections and/or floral lists from numerous other publications by various authors. Its use is for information purposes only, not for citation in the literature.
Note: Rattlesnake flora remains poorly known. Taxa included in this list are based on presence of species in comparably-aged floras, i.e. the "Kahneeta Flora" and extrapolations from the "Deschutes Flora".
