Note: The classification of the angiosperms follows Chase and Reveal (2009. Bot. J. Linn. Soc. 161: 122-127); of ferns, Christenhusz et al. (2011. Phytotaxa 19: 7-54); and of conifers, Christenhusz et al. (2011. Phytotaxa 19: 55-70). This list includes all named taxa. Genera recognized by Berry (1925, 1938), are classified according to where the extant taxa belong in the APG III system, although this should not be taken as an endorsement of the application of these names to the Laguna del Hunco fossils.
