Knobloch (1958) described leaf forms which he assigned to Acer palaeosaccharinum STUR as follows (translation from Czech): “Leaves 3–5 lobed, base rounded to subcordate, margin widely simple to double dentate with teeth of different size. Venation palmate, basal veins at 40–50°, secondary veins craspedodromous, only slightly bent, tertiary veins forming polygonal fields.” The blades are 16 to 76 mm long and 18 to 85 mm wide. The epidermal structure was not preserved. D i s c u s s i o n. This species prevails in the Knížecí leaf assemblage. As noted above, aberrant leaf forms of Acer palaeosaccharinum can be misinterpreted as A. angustilobum .
