Abstract

Proportional counts (200/ sample) of pollen present in nine samples of surface sediments from a settling basin in Miller's Bay, Lake Okoboji, Iowa, are summarized. In order of decreasing abundance the types of pollen listed are Compositae, Quercus, Gramineae, Pinus, Ulmus, Picea, Carya, Tilia, ]uglans, Ostrya, Fraxinus, Betula, Salix, Acer negundo, fem (spores), Celtis, Myriophyllum, Sparganium, Typh,i Alnus, and Potamogeton. The period of "pollen rain" for Tilia americana was determined to be from June 27 to July 14 (in 1964). Pollen found in algal mats collected during this period contained 15 types of pollen, of which Tilia pollen was the most abundant.
