Dennstaedtiaceae is the only family of ferns in the order Dennstaedtiales. It includes the world's most abundant fern, Pteridium aquilinum (bracken). Members of the order generally have large, highly divided leaves and have either small, round intramarginal sori with cup-shaped indusia (e.g. Dennstaedtia) or linear marginal sori with a false indusium formed from the reflexed leaf margin (e.g. Pteridium). The morphological diversity among members of the order has confused past taxonomy, but these genera appear to be united in genetic analyses.
