Fig. 4. Light micrographs of the stem of extant chloranthacean angiosperm Sarcandra glabra (Thunberg, 1794) Nakai, 1930. Images taken from the database of Japanese woods of the Forestry and Forest Products Research Institute (http://db.ffpri.affrc.go.jp/WoodDB/JWDB-E/home.php; accessed in 2019). A. Transverse section of the stem, pith almost entirely missing, secondary xylem with growth rings, secondary phloem and bark. B. Secondary xylem in transverse section, two interfascicular rays (ir) and fascicular secondary xylem (fx) intercalated. White arrow pointing uniseriate fascicular ray. Black arrow pointing protoxylem. C. Detail of bark and secondary phloem. Note phloem with AVES pattern as well. Phloem cells preserved and phloem fibers cap (black double headed arrow) separated by interfascicular rays. Bark (white double headed arrow) with a continued thickened layer. D. Tangential section of the stem, arrows pointing fascicular uniseriate rays in fascicular xylem (fx). Interfascicular rays (ir) intercalated. Scale bars 50 μm, except A, 1 mm.
