October Wild Flower Records
Hamilton, Ontario, Canada
Updated to October 31, 2007
I am updating Latin names from "FLORA Ontario – Integrated Botanical Information System"
as I find errors in my older records.
These are records of 260 species seen in bloom in October during the last 9 years in the Hamilton Area.
There have been 37 new species for October found blooming since 2004.
