FIG. 20 in Bark anatomy of lianescent Bignoniaceae: a generic synopsis

FIG. 20. — Phylogenetic mapping of the synapomorphies delimited in this study: 1, xylem furrowed by phloem wedges; 2, fibrous or semi-fibrous phloem; 3, multiple of four phloem wedges; 5, prismatic crystals in the phellem (*), found only in Amphilophium crucigerum; 6, storied structure; 7, interxylary phloem; 8, fibers scattered in the phloem; 9, multiple dissected phloem wedges, non-lignified parenchyma in wood; 10, phloem fibers tangentially elongated; 11, four conspicuous phloem arcs; 12, fibers absent in the regular phloem, sclereids found instead; 13, fibers absent in the phloem, sclereids found instead; 14, hollow stems; 15, limiting rays without lateral steps; 16, symmetrical lateral steps on both sides of the phloem wedges.
