162 AUTUMN NOTES IN IOWA 



10. A few September flowers found in central and 

 eastern Iowa, 1906-1909. (In popular names this list 

 follows Greene; in scientific names, Gray's Manual, ed. 

 of 1908. While the writer has analyzed all specimens 

 and taken care Avith classification, it cannot be guaran- 

 teed that all the species are correctly given. Many speci- 

 mens were first detennined from the sixth ed. of Gray's 

 Manual . Comparison of this edition, that of 1908, and 

 Greene reveals the usual lack of fixity in both popular 

 and scientific names which vexes the amateur botanist, 

 year after year, from Atlantic to Pacific.)
