Abstract
Petrified woods obtained from the Oligocene of Tsuyazaki, Fukuoka Prefecture have been studied, and four new species ofPrunus (Rosaceae) are described:Prunus palaeozippeliana, P. ascendentiporulosa, P. uviporulosa andP. polyporulosa. These four species are very similar to each other in gross anatomical features and are characterized by the diffuse porosity, exclusively simple perforation plates, spiral thickenings on vessel walls, heterogeneous rays and the presence of traumatic gum canals. The petrified woods ofPrunus are new records from the Tetiary of Japan.
