Cordaixylon dumusum n. sp.
Shrublike plants with stems up to ca. 5 cm and profuse adventitious rooting from nodal regions. Needle-like leaves at base of branches wiht spatulate leaves up to ca. 3 cm wide distally on some branches, needle-like leaves only on others. Phyllotaxis approaching 3/8, 5/13, and 8/21, with traces diverging from pith as single bundle in smaller stems and as double bundle in largest stems. Adventitious root traces not attached to primary xylem of stem or leaf, diverging at nodes distal to leaf trace and proximal to branche trace emission. Leaves hypostomatic with single rows of stomata. Leaf traces collateral, surrounded by distinct sheath and separated by compact, undifferentiated mesophyll. Leaf sclerenchyma of longitudinally oriente columns typically separated by two bundles; hypodermal sclerenchyma absent distal to leaf base. Cones irregularly arranged on both apical and proximal stem regions; xylem of cone axis often not continuous with xylem of stem. Pollen cones with five sporangia per cone scale, Florinites-type pollen 47-66 µm in greatest dimension.
