Question
I thought this was Osmunda regalis, but now I am less sure. I see what look like spore-bearing structures on the leaflet margin, but would that make it O. claytoniana (interrupted fern) rather than O. regalis? Perhaps it is a young plant, or a hybrid?
Answer
Dear suecar, your plant is most likely Osmunda regalis. Occasionally, sporangia appear to unusual locations on these plants (for a variety of reasons). The hybrid between these two plants is very rare (only two confirmed collections in the world).
