M a t e r i a l. IBUG cf.1136 + 1137 (part + counterpart), cf. 2819a, NHMW 1878/6/2701 + 2702 (part + counterpart), 2800 + 2801 (part + counterpart), 7806.
D e s c r i p t i o n. Leaves lacking petiole; lamina obovate, l × w about 70–132 × 20–43, l/w = 2.2–4.7, base cuneate, apex widely acute to short acuminate; margin entire to sub-entire, teeth tiny, sparse, mainly in upper part of lamina, exceptionally also in lower part (NHMW 1878/6/2701 + 2702); midvein straight, strong; secondaries eucamptodromous to semicraspedodromous, much thinner than midvein, widely spaced, curved towards apically (convex), somewhat steeper in lower part than in apical part; simple intersecondaries present, paralleling secondaries.
R e m a r k s. Specimens IBUG 1136 + 1137 and IBUG 2819a are assigned as cf. because the length/width ratio is about 2.2 to 2.3 and thus lower than in the other specimens. Differing from Dicotylophyllum sp. S see that taxon.
Differing from cf. Gordonia (?) oberdorfensis KOVAREDER by lower vein density, course of secondaries and minutely toothed margin.
