Notes on unassigned taxa: Fossil Allophylus and Rhus both have somewhat thickened textures as well as marginal teeth and thus appear ambiguous with regard to deciduousness. Both genera have evergreen and deciduous representatives today, including species that are both evergreen and toothed. Magnoliaceae sp. has a slightly thickened texture and an untoothed margin, suggesting an evergreen habit.
