I believe this is a Cuckoo Flower (Cardamine pratensis), one of the mustards. The photo doesn't really show the delicate lilac colour of these blossoms. I'm starting to have more and more of an appreciation for the mustards.
This tiny flower was growing next to it, both at the edge of a pond. I've yet to identify it, so if anyone has any suggestions… The blossoms are only about 5 mm across.
And finally, I've been meaning to stop for awhile and photograph these Bog Saxifrage (Saxifraga hirculus) that are growing in a marshy area beside the road to Victor Bay. Their deep yellow really stands out against the grasses and sedges they are growing amongst.
