Dennstaedtia

Dennstaedtia is a primarily tropical genus of ferns described as a genus in 1801. Hayscented fern, or Cup ferns, are common names for some species in this genus. Its best-known member is probably the temperate North-American hay-scented fern, "Dennstaedtia punctilobula" (pictured in the taxobox), which forms extensive clonal ground-cover colonies on level surfaces in the Appalachian area.
