We saw these flowers near Noddy Bay, Newfoundland. I'm hoping that someone can tell me the name.
I've searched for joint grass, snap grass and horsetail but haven't seen any pictures that look like these. I added a close-up of one blossom (click on picture to enlarge). It looks like the blossom is on a young joint grass stem.
If you have any suggestions I will be most grateful. Unfortunately I only own field guides for the western region of N. America.
