Onoclea refers to a type of fern that typically grows in damp areas and is characterized by its deeply lobed fronds. Some common synonyms for onoclea include the sensitive fern, the beaded fern, and the interrupted fern. The sensitive fern gets its name from its tendency to wilt quickly when it is exposed to harsh sunlight or dry conditions. The beaded fern owes its name to the bead-like structures that can often be found on its fronds. Finally, the interrupted fern gets its name from the fact that its fertile fronds are often "interrupted" by clusters of spores, which can be seen as darker spots on the fronds.
