My purpose in writing this list is to place on record data gathered principally from the pioneers of Sac County about the conditions in pioneer days and since. While these data are not as accurate as though they were confirmed by specimens, they are better than no information at all. I have used extreme care in differentiating species and have included some observations of my own made in the more recent years. I have also included some data on adjoining counties.
