METHODS The sampling and processing techniques were the same as described in Urban and KHne (1970). Five strew mount micro- scope slides were prepared of the residue from each sample interval using Clearcol for the mounting medium and the method of Wilson (1959). Individual specimens were prepared for examination with the scanning electron microscope using the procedures outlined in Urban and Padovani (1970). Slides containing the type specimens have been deposited in the

Slides containing the type specimens have been deposited in the palynological repository of the University of Oklahoma, Norman, Oklahoma. The number sequences for type specimens refers to sample number, slide number, and ring number on the slide.
