FIG. 20 in Fossil wood from the lower Miocene of Myanmar (Natma Formation): palaeoenvironmental and biogeographic implications

FIG. 20. — Indet. sp. 1, MNHN.F.50199 (A-F): A, Ts, vessels and few vasicentric parenchyma, solitary secretory canals (arrows) or in short tangential lines, surrounded by parenchyma, remarkably bigger than vessels; B, C, Tls, 1-4-seriate rays with sometimes long uniseriate row of marginal cells (arrow); D, Tls, parenchyma cells (white arrow) and secretory canal (black arrow); E, Tls, detail of secretory canals in short tangential line; F, Rls, heterocellular rays with procumbent cells (black arrow) and square or upright cells (white arrow). G-J, Indet. sp. 2, MNHN.F.50200: G, Ts, poorly preserved wood, vessel arrangement often in groups; H-I, Tls, 1-5-seriate rays, with maybe sheath cells (arrows); J, Rls, heterocellular rays with procumbent and square or upright cells. Scale bars: A, G, 1 mm; B, H, 500 µm; C-F, I-J, 200 µm. Abbreviations: see Fig. 2.
