fossil leaves and flowers

Twig showing attached leaves and winged fruits of Cedrelospermum. Figure 2 in Manchester, S.R. 1989. Attached reproductive and vegetative remains of the extinct American-European genus Cedrelospermum (Ulmaceae) from the Early Tertiary of Utah and Colorado. American Journal of Botany 76:256-276. Correction: The correct citation of this is Cedrelospermum nervosum (Newberry) Manchester, not C. nervosum (Cockerell) Manchester as indicated in the figure caption. (This is also figure 12.6A in Manchester 1989, systematics and fossil history of the Ulmaceae).
