D e s c r i p t i o n. Specimen no. NHMW_7 (Pl. 20, Fig. 1) is an entire-margined leaf impression of narrow deltoid shape, with wide cuneate base. Leaf lamina is widest in its 1/3 (30 mm), and narrows longitudinally and symmetrically towards apical part. Leaf impression is 93 mm long. The primary vein is relatively robust (up to 3 mm wide near base), and slightly narrows towards the apex. Secondaries are finer, but still relatively robust, terminating in leaf margin. Third order venation not observed.
D i s c u s s i o n. Dicotylophyllum sp. 2 differs from D. macrophyllum , Dicotylophyllum sp. 1 , Dicotyllophyllum sp. 3 and Dicotyllophyllum sp. 4 in having deltoid leaf lamina and relatively robust midvein.
