October Wild Flower Records
Hamilton, Ontario, Canada
Updated to October 31, 2009
I am updating Latin names from "FLORA Ontario – Integrated Botanical Information System"
as I find errors in my older records.
These are records of 268 species seen in bloom in October during the last 11 years in the Hamilton Area.
There have been 45 new species for October found blooming since 2004.
