Dicotylophyllum sp.

Pl. 2, Fig. 9

M a t e r i a l. 1 specimen, Líšeň-Neklež ( MB108 ) .

D e s c r i p t i o n. Incomplete leaf widely elliptic, 72 mm long by 42 mm wide, base widely cuneate, petiole fragmentary, apex not preserved, margin preserved only at basal part, entire, venation simple craspedodromous, midrib moderate, straight, secondary veins thin, distinct, alternate or opposite at basal part, 8 pairs preserved, interspaced at wide distances (up to 12 mm), curved towards apex and margin, originating at 40° to 60°, tertiary veins percurrent often straight or forked, higher order venation regular polygonal reticulate, areolation well-developed, 3- to 4-sided.

R e m a r k s. This leaf resembles Betulaceae due to its relatively large lamina and widely spaced secondary vein pairs. However, the absence of the margin does not allow a specific assignment. Bůžek (1971) described leaves as Alnus sp. from Čermníky (North Bohemia, the Czech Republic), which morphologically resemble our material and leaves of A. menzelii RAN. -BOBR. and A. rostaniana SAPORTA emended by Mai and Walther (1991) known from the late Oligocene and Early Miocene of Europe ( Teodoridis 2002).
