White Blue-eyed Grass (Sisyrinchium albidum)

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.
