FIGURE 5 in Re-establishment of Begonia corallina Carrière (Begoniaceae) based on morphoanatomical evidence

FIGURE 5. Stem cross section of Begonia corallina (A, C, F) and Begonia maculata (B, D, E, G). A–B. Overview showing epidermis (Ep), cortex formed by collenchyma (Co), parenchyma (Pa) and sclereids (Sc), vascular bundles with phloem (Ph) and xylem (Xy) and parenchymatic pith (Pi). C–D. Details showing epidermis (Ep) and collenchyma (Co) with anthocyanin in the vacuole in fresh samples. E. Glandular trichome with unicellular base (Bc), stalk (St) and multicellular secretory head (Hc). F. Vascular bundles with phloem (Ph), vascular cambium (Vc) and xylem (Xy). Note the presence of perivascular fibers (Fi) in F. Bars: A–B, F = 30 µm, C–E = 60 µm, G = 120 µm.
