Description. Leaves mostly large, narrowly ovate, rarely narrow-elliptic, narrow-oblong or ovate, asymmetric, base mostly deeply cordate, asymmetric, rarely cuneate-rounded, apex acute or slightly attenuate. Length of leaves 6.2 to ca 13 cm, width (2.2) 3.2-6.0 cm, petiole 3-5 mm. Venation craspedodromous. Primary vein straight, stout. Secondary veins numerous, up to 18 (or even more) pairs in number, commonly arched throughout the leaf, not just in the apical part. Secondary veins occasionally forked, usually only in the cordate base, rarely in the mid-leaf. Secondary veins up to 1.0 cm apart. In the lower part of the leaf the secondaries diverge from the primary vein at an angle of 60-70° in the middle part at 50° and in the upper 40°. On some specimens there is visible branching of the secondaries at the leaf margin, but the third order venation is very poorly visible or not preserved at all. Because of the very poor state of preservation the leaf margin is incomplete. Most specimens possess only some marginal teeth which are distinct and simple (as in Zelkova leaves), particularly in the upper part of the leaf. In the middle part there is often small additional tooth on the lower side of each tooth. Remarks. As stated by KVACEK and HABLY (1991), the leaves of U. pseudopyramidalis "differ primarily in the strongly asymmetric leaf base, coarser teeth and partly also in their greater size". They are most commonly large, with very characteristic arched secondary veins which diverge from the central vein at widely spaced intervals. The "Zelkova "-like teeth, sometimes with a small addi-
