Incomplete and fragmentary simple leaves, petiolate, lamina elliptic to ovate 20–27 mm long, 10–14 mm wide, base cuneate with fragmentary petiole (5 mm long), apex not preserved, margin entire, venation brochidodromous, midrib strong, straight, secondary veins thinner, straight, looping by margin, alternate, originating at an angle of 30–50°, tertiary veins perpendicular, straight, venation of higher orders regular polygonal reticulate, areolation well developed, 4-sided, free ending veinlets absent. Adaxial epidermis medium cutinized, non-modified cells polygonal, ca. 25 µm in diameter with slightly to strongly wavy anticlinal walls, abaxial epidermis thinly cutinized, non-modified cells with straight to wavy anticlines, stomata brachyparacytic, guard cells deeply sunken, with inner subsidiary cells often asymetrically developed, 12–15 (–20) µm long and additional outer subsidiary cells, less modified, simple small trichome bases on veins, lens-shaped oil cells in mesophyll.
D i s c u s s i o n: Kvaček (1966) believed that this material should be conspecific with Litsea edwardsii BANDULSKA (1926) , which it matches well in the structure of the abaxial cuticle. At present we hesitate to accept this view considering the very different age (middle Eocene) and associated flora at the type locality Bournemouth .
