M a t e r i a l. Oriolo MSF 677, 821.

D e s c r i p t i o n. Leaflet, lamina ovate or ovateelliptic, 24–27 mm long, 13–17 mm wide, base obtuse or bluntly acute, apex obtuse with a cusp, secondary venation craspedodromous, margin coarsely serrate, teeth usually with secondary teeth, tooth basal side long convex, apical side shorter concave, straight or convex.

R e m a r k s. The leaflets are fairly similar to the extant species Sorbus aucuparia L., 1753. Sorbus aucuparia displays a marked leaf polymorphism with leathery leaves approaching the morphology of S. domestica , while chartaceous leaflets of seedlings and shade conditions commonly show the coarse dentition with secondary teeth, as seen in the fossil material.
