Dicotylophyllum sp. W

Pl. 6, Fig. 1

M a t e r i a l. NHMW 1878/6/2346a + 9529 (part + counterpart).

D e s c r i p t i o n. Leaflet (?), probably sub-sessile; lamina oblong, basally slightly asymmetrical, l × w = 68 × 19 mm, ratio l × w = 3.5, base slightly (?) convex or (?) cuneate, apex acute; margin densely, regularly crenate to serrate, sinus and apex rounded; midvein slightly bent; secondaries semicraspedodromous, dense, arising at wide angles, rather straight, only minimally curved towards apex (convex), interspaced with intersecondaries, appearing rather irregular; secondaries and intersecondaries looping at variable distance from margin; exmedial veinlets further looping close to margin, veinlets running towards margin and into teeth; tertiaries reticulate.

R e m a r k s. This specimen, especially its leaf margin, is reminiscent of “ Arbutus ” serra UNGER.

Differing from Fraxinus sp. by the dense and irregular venation and densely spaced teeth with rounded sinus and apex.

Differing from Leguminophyllum sp. I by the crenate to serrate margin and irregular pattern of secondary and higher order venation.

Differing from Prinsepia serra (UNGER) KOVAR- EDER et KVAČEK by rounded and regular teeth.

Differing from Ternstroemites pereger by more crenulate than serrate margin, absence of glands on teeth, wider angles of secondaries, irregular pattern of secondaries and intersecondaries, and marginal venation pattern.
