Quercus sp. div.

Pl. 5, Fig. 11

M a t e r i a l. Quercus pollen grains were observed in all studied pollen samples.

R e m a r k s. Pollen grains are very abundant and well-preserved. The challenge to precisely discriminate the different deciduous, semi-deciduous and evergreen components of the genus Quercus under the optical microscope led us to organize the oak pollen into two main types: the first one including deciduous oaks, e.g., Quercus pubescens WILLD. , and semi-deciduous oaks, e.g., Quercus cerris L. - type, the second one Quercus ilex L. - Q. coccifera L.- type (including all evergreen oaks). However, the Quercus ilex-coccifera - type pollen grains are very rare.
