Pteridium aquilinum (Bracken or Common Bracken) is a species of fern with a cosmopolitan distribution, occurring in temperate and subtropical regions throughout much of the world, including most of Europe, Asia, and North America in the Northern Hemisphere, and Australia, New Zealand and northern South America in the Southern Hemisphere.
It is often treated as the sole species in the genus Pteridium (brackens), though other authors split it into up to 11 separate species.
It is a herbaceous perennial plant, deciduous in winter. The fronds are produced singly from an underground rhizome, and grow to 1-3 m tall; the main stem is up to 1 cm diameter at the base.
The plant is carcinogenic, 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 [1]. The spores have also been implicated as a carcinogen.
