This paper reports the palaeoxylotomical study of petrified conifer remains from Velitzelos collection, orig-inating from some fossiliferous sites of Greece, especially from the Aegean area (Evros, Limnos, Lesbos), aged of late Oligocene to early Miocene. Ten species were identified: Cupressinoxylon akdikii, Juniperoxylon acarcae, Tetraclinoxylon velitzelosii, Taxodioxylon gypsaceum, Taxodioxylon taxodii, Glyptostroboxylon rudolphii, Glyptostroboxylon tenerum, Pinuxylon pineoides, Pinuxylon halepensoides and Pinuxylon sp. aff. Pinus canariensis. These new identifications add new elements to the forest assemblages of the Oligocene - Miocene Greek flora, useful for understanding the evolution of the Cenozoic palaeovegetation and palaeoclimate in the Aegean area.
