I posted Three ferns for ID three years ago, and two of them were ferns I've been wondering about for a while in the West End. I finally came up with some names, two of which were in that posting. I have just posted the Matteuccia struthiopteris in another thread. Here is Pteridium aquilinum, bracken or brake fern. Please correct me if I have this ID wrong. I have heard the term "bracken" forever, but had no idea what it looked like. There is a child who I hope is mostly obscured, at the right of the first photo, giving an idea of the size. What interested me about this is the level of divisions on the leaves, on some twice pinnate, others three-times pinnate, or different on different parts of the leaflets. Are there sori starting to develop on the pinnulet margins on the last photo in this set? I guess I should have called the whole thing here "frond" rather than leaf. It's way too much trouble to fix that now.
