Ulmus sp. 2. (Plate I: 8, Fig. 17) • Material: No. 90. 26.1. (1 specimen). Description: Length of leaf 1.0 cm, breadth 1.1 cm. Its shape is rounded, as is base, apex missing. Length of petiole 0.1 cm. Margin is toothed with 3 large teeth. Venation craspedodromous. It might be an aberrant leaf of the above-mentioned species. Ulmus sp. 3. (Plate I: 9; Fig. 16) Material: No. 90. 27.1. (1 specimen). Description: Length of the leaf 5.7 cm, breadth 3.2 cm. Its shape is elliptic. Petiole is very strong, its breadth 0.2 cm, length 0.8 cm. Margin toothed teeth are large, but not well preserved. Venation craspedo­doromous, secondary veins ir regular issued from the midrib at 0.4-0.6 cm distança from each other. Angle of divergencee 53°-58°. Buxaceae Buxus L.

Material: No. 90. 30. 1.; 90. 31. 1. (2 specimens). Description: Length of the whole leaf 2.0 cm, breadth 1.8 cm. Shape ovate, apex retuse, base acu­te, margin entire. Midvein strong, venation pinnate secondary veins are very thin and dense. Anatomy: Upper epidermis composed of straight-walled polygonal cells varying from 21-24 um in size. The lower epidermis comprising polygonal cells with more or less straight walls. Thee size of epidermal cells varies from 22-26 p.m. Anomocytic stomata confined to the lower surface, oval or rounded, varying 28­33 pm in length and 21-26 um in width. The stomata with polar T-pieces and prominent outer ring are not ar­ranged in distinct groups. Trichomes or papillae of the thickly cutinized leaf surface are absent. Hamamelidaceae Parrotia C. A.
