First record of Styracoxylon (Styracaceae) from Southern Hemisphere: Arroyo Feliciano Formation (Upper Pleistocene), Entre Ríos, Argentina

The axial parenchyma is apotracheal diffuse and diffuse-in-aggregates, and in strands of 8-12 cells. Vascular tracheids possibly present. Wood anatomical features suggest a relationship with Styracaceae, and the fossil specimen shows affinity with the extant genus Styrax Linnaeus.
