R e m a r k s. Acorns of this type are produced by several western Eurasian species of Quercus sect. Quercus , Q. ilex

M a t e r i a l. Oriolo MSF 633, 688,?697,?701.

D e s c r i p t i o n. Leaf, simple, petiolate, lamina elliptic, 50–62 mm long, 25–30 mm wide, shallowly lobed, number of lobes 5–6, base cordate, auriculate, apex rounded acute.

R e m a r k s. The distinction between Quercus pubescens and Q. petraea L. is not straightforward. Quercus pubescens leaves commonly have a cordate or auriculate base and broadly rounded lobe apices. In Europe, Q. petraea leaves never have a cordate base, and lobes are rounded triangular. However, eastern populations of the closely related Q. iberica M.BIEB., 1808 (syn. Q. petraea subsp. polycarpa (SCHUR) SOÓ, 1943 ) commonly have cordate leaf bases, but differ from Q. pubescens in their higher number of secondary veins and lobes.
