FIG. 16. — Shoreoxylon cf. sumatraense Du, MNHN.F.50193: A, Ts, vessel often in groups, sometimes in clusters (arrows); B, Ts, long tangential lines of secretory canals (arrows) close to each other; C, D, Tls, 1-4-seriate rays; E, Tls, 3-seriate rays with a uniseriate row of six marginal cells (white arrow), abundant parenchyma (black arrow), 4-8 cells per strand; F, Rls, vessel-ray pits irregular in shape, simple with reduced borders (arrows); G, Ts, synthetic drawing of the transversal section (with only some vessels and rays displayed), visible bands of parenchyma as grey lines and recognized secretory canals as red dots, arranged mostly in long and closely spaced tangential lines; H, Rls, vasicentric tracheids (arrows); I, Rls, heterocellular ray with square or upright marginal cells (arrows).
