Rosaceae gen. et sp. indet. 2

Pl. 6, Fig. 6

Incomplete leaf obovate in outline, 16 mm long and 8 mm wide, base cuneate, apex obtuse, margin coarsely serrate, teeth acute, venation semicrapedodromous, midrib moderate, curved, secondary veins thinner, straight, alternate to subopposite, at angles of 30–40°, looping by the margin, principal veins innervate in sinus, tertiary veins alternate to opposite percurrent, straight to sinuous, venation of the higher orders regular polygonal reticulate, areolation well developed, areoles 3- or 4-sided, veinlets probably lacking.

The leaf could also be assigned to the Rosaceae but with hesitation, however the innervetion of teeth sinuses may also indicate an affinity to the Oleaceae ( Fraxinus LINNAEUS ).
