“Crinkleroot” refers to a type of plant, specifically the “Crinkleroot” fern, which is also known as “Cystopteris” or “Cystopteris fragilis.” It is a delicate fern that typically grows in rocky, shaded environments. The term can also relate to its characteristic leaves that have a crinkled appearance. However, the word can be used more broadly in some regions to refer to various ferns or plants with similar textures.
