From How To Know The Wildflowers:
It seems unfair that this familiar and pretty little plant should be without any homely English name. Its botanical title signifies "Canada Mayflower," but while undoubtedly it grows in Canada and flowers in May, the name is not a happy one, for it abounds as far south as North Carolina, and is not the first blossom to be entitled "Mayflower."
In late summer the red berries are often found in close proximity to the fruit of the shin-leaf and pipsissewa.
