Leaf trilobate. Petiole up to 6.5 cm long and 1 mm wide. Sinus between lobes more than 80% of lamina length, structurally reinforced by lamina tissue. Margin toothed with angular sinus; five to ten serrations per cm with axes inclined to the tangent of the leaf margin; apical angle of tooth acute. Primary venation actinodromous; primary veins massive with straight course. Middle lobe base symmetrical whereas lateral lobe bases strongly asymmetrical. Secondary veins thin; angle of divergence moderate to wide acute; course of secondary veins uniformly curved before joining exmedial branches of superadjacent secondary vein forming intercostal regions irregular in shape and size; intersecondary veins common. Veins of secondary order or higher poorly preserved. Number of specimens examined. 1. Specimens illustrated. UF 15706-24677 ( Figure 4.2 ). Occurrences. Braun Ranch and Hoisington III localities, Kansas . Remarks. This species is common in the Braun Ranch locality, Kansas (Wang and Dilcher, 2006a). Though only one specimen is observed from the Hoisington III locality, a suite of characters, including trilobate leaf, massive multi-stranded primary vein, secondary venation pattern, and its chloranthoid tooth type are consistent with those described by Wang and Dilcher (2006a).
