The specimens featured in the photos on this page were found in two separate locations on the Bruce Peninsula. The first three photos are of one specimen.

Unfortunately, when I found these specimens I did not know or note the key determining feature of White Blue-eyed Grass: two spathes (leafy bracts) where the flower stalks emerge. Close examination of the photos I did take seem to indicate the two spathes, but this is not clear. So there is a possibility that these are not photos of White Blue-eyed Grass after all.
