Not all species contain ptaquiloside, such as Diplazium esculentum, a fern with fiddleheads regularly consumed in parts of East Asia, which differs from bracken (Pteridium aquilinum). [4] The fiddlehead resembles the curled ornamentation (called a scroll) on the end of a stringed instrument, such as a fiddle.
Bracken (Pteridium) is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm).

The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, and grow to 0.3–1 metre (1– 3 + 1 ⁄ 2 feet) tall; the main stem, or stipe, is up to 1 centimetre (1 ⁄ 2 inch) in diameter at the base.
Several ferns, such as bracken [55] and Azolla [56] species are noxious weeds or invasive species. Further examples include Japanese climbing fern ( Lygodium japonicum ), sensitive fern ( Onoclea sensibilis ) and Giant water fern ( Salvinia molesta ), one of the world's worst aquatic weeds.
The young fronds are stir-fried and used in salads. [6] [7]They may have mild amounts of fern toxins but no major toxic effects are recorded.
