    Description: There is much variation in leaf shape in species of deciduous trees, often making species identification difficult. The example here is three variants of the sassafras-like tree leaf, ?Lindera varifolia, from the 18-inch layer of the FBM. Left) Non-lobed variant; specimen FMNH PP53395 from FBM Locality A measuring 260 millimeters in length. Middle) Two-lobed variant; specimen FOBU 10668 from FBM Locality A measuring 420 millimeters in length. Right) Three-lobed variant; specimen FMNH PP53567 from FBM Locality A measuring 300 millimeters in length

    Description: Lindera varifolia MacGinitie, 1969, from the 18-inch layer of FBM Locality A. Left) Trilobed variant of a very large sassafras-like leaf (Family Lauraceae?). Total length is 300 millimeters. Specimen is FMNH PP53567. There is much variation in shape of this species (see Fig. 157), but note the very long petiole, smooth leaf margins, and Palmate venation. Right) Winged seed measuring 60 millimeters in length that possibly belongs to this species. Specimen FMNH PP54857
