- Apical part of a simple entiremargined leaf; 36 mm long (incomplete, probably twice that long), 7 mm wide (completed ? 30 mm), shape of lamina ? elliptic, apex ? acute, only the straight midvein is visible. Adaxial cuticle (Pl. 8 fi g. 2): rather thick, glabrous; size of non-modifi ed epidermal cells 24–43 μm (33 μm), anticlines distinct, very narrowly U to Ω-shaped undulate, 2–4 μm thick. Abaxial cuticle (Pl. 8, fi g. 1): rather thick, brittle, only small fragments preserved; type of stomatal complexes questionable because subsidiary cells not visible; stomata surrounded by an elevated ridge with lateral/ radial cuticular striation, stomata large oval to roundish, 28–42 μm (36 μm) long, 23–31 μm (26 μm) wide, epidermal walls of guard cells sometimes hardly traceable, outer stomatal ledges of the guard cells thickened, straight, stomatal aperture a long slit almost reaching the poles, 19–34 μm (27 μm) long; anticlines of the non-modifi ed epidermal cells not visible; big, one-celled, strongly cutinized, round trichome bases in intercostal areas present but rare, outer diameter 22–25 μm (23 μm); no trichomes preserved.
