Pteridium aquilinum

Description:

It is a herbaceous perennial plant, deciduous in winter. The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, and grow to 1-3 m tall. It is a very adaptable plant, it readily colonises disturbed areas. The plant contains the carcinogenic compound ptaquiloside, and communities (mainly in Japan) where the young stems are used as a vegetable have some of the highest stomach cancer rates in the world. The spores have also been implicated as carcinogens.
