PFN000565 (for new genus).

E t y m o l o g y. The epithet Cercioxylon originates from the modern genus Cercis L. Because the fossil wood has very similar features to the wood of Cercis , I prefer to use this name for the new genus.

D i a g n o s i s. Wood semi-ring to ring porous. Vessels are in radial multiples and clusters, common or sometimes diffuse. Perforation plates simple. All rays procumbent in general, and body rays procumbent with one to four upright cells. Axial parenchyma paratracheal to vasicentric and in confluent type, banded, and in dendritic to net-like groups with vessels, and axial parenchyma storied, 2–4 cells per parenchyma strands. Ray width up to 5 seriate (2–4 in general), and uniseriate rays 5–15 cells. Vestured ray pits present ( Akkemik 2019 ).
