Pinnularia; Iowa Diatoms
Forty-three (43) taxa of Pinnularia collected from a Sphagnum bog in north central Iowa are added to the state records for this genus. The numbers of Pinnularia entities are generally much larger in this habitat than in other Iowa habitats. Furthermore, the size ranges of many taxa exceed those given in published descriptions. As of 1972, published records for the state number sixty-four (64) taxa in this genus.
