Podocarpoxylon Gothan reviewed in the light of a new species from the Eocene of Patagonia

A new species of Podocarpoxylon Gothan is described based on samples collected from sediments of the Rio Turbio Formation. The fossil-bearing strata are lower Eocene (47-46 Mya) according to recent geochronological ages. The new species has indistinct growth ring boundaries, abundant and frequently tangentially zonate axial parenchyma, uniseriate pitting on radial walls, one half-bordered pit (= oculipore) with reduced borders and vertical aperture inclination per cross-field and medium height uniseriate rays. The new material is compared with all fossil-species of Podocarpoxylon and an inventory of all Podocarpoxylon species previously described is provided. Cross-field characters of the new species indicate affinity to the Podocarpaceae. The presence of Podocarpaceae wood augments other evidence of this family from the same stratigraphic unit.
