M a t e r i a l s t u d i e d. Foliage impressions PA 1154.1–2, 1162.1–2, 1163.6–10, 1170.10 (two leaves on a twig), 1191.2, 1368, 1370, 1379, 1429.

D e s c r i p t i o n. The leaves are shortly petiolate, petiole max. 4 mm long, blade lanceolate, often slightly asymmetric at base, apex acute, base rounded to shallow cordate, margin finely double serrate to serrate, 40–80 mm long and 10–20 mm wide, venation craspedodromous, secondaries quite dense, at an angle of 30–60°.

D i s c u s s i o n. Ulmus pyramidalis   is a common Miocene element in North Bohemia ( Bůžek 1971), which replaces Ulmus fischeri HEER   , a characteristic element in the early Oligocene (e. g. Bechlejovice – Kvaček and Walther 2004) and in the late Oligocene volcanic floras of the České středohoří Mts. The occurrence of Ulmus pyramidalis   at Matrý is one of the earliest records in this area.
