2004 Dicotylophyllum sp. 1 ; Kovar-Eder et al., p. 88, pl. 15, fig. 1.
A d d i t i o n a l m a t e r i a l. cf. GBA 2005/0004/0024.
D e s c r i p t i o n. Leaves alternate, shortly petiolate; lamina narrow elliptic to obovate, l × w up to 62 (inferred) × 18 mm, ratio l/w about 3–3.4, base narrow cuneate to decurrent, apex incomplete, emarginate (GBA 2005/0004/0024); margin entire near base, upper two thirds widely simply serrate, teeth triangular, sinus acute to rounded, apex bluntly acute to rounded; midvein straight or bent: secondaries delicate, semicraspedodromous, densely spaced, at moderate angles, rather straight, looping near margin; veinlets entering teeth; higher order veins not preserved.
R e m a r k s. The apex is only preserved in specimen GBA 2005/0004/0024. Whether the emarginate apex resulted from damage is uncertain.
Differing from Dicotylophyllum sp. G by the secondary veins which are not diverging towards the leaf margin.
Differing from Dicotylophyllum sp. M by the straight course of the secondaries.
Differing from Dicotylophyllum sp. T by elliptic shape, entire margin near base and less sharp teeth.
Differing from leaflets of Engelhardia orsbergensis by symmetry, cuneate base, broader shape and broader teeth.
