Fig. 3. SEM images of the secondary xylem of the chloranthacean angiosperm Sarcandraxylon sanjosense gen. et sp. nov. (IAA-Pb 621), San José Pass, Antarctica, early–middle Campanian. A. Transverse section of the stem, showing one vascular bundle in the middle, pith toward the right, white arrows pointing uniseriate fascicular rays. B. Parenchymatic cells of an interfascicular ray in transverse section showing the main shape and piritization of the cell walls. C. Secondary xylem in longitudinal tangential section, showing fascicular xylem (fx) and interfascicular rays (ir). D. Longitudinal section of fascicular xylem; D1, showing tracheids and a two cells tall uniseriate ray (white arrow) with elongate upright cells; D2, detail showing cell walls partially replaced with framboidal pyrite (white arrow).
