Spleenworts
The spleenworts (Asplenium) are a diverse and widely distributed group of ferns, including not only spleenworts, but also the bird's nest ferns and the walking ferns, which are segregate members of the genus. They are an important food source for butterflies and moths, and some species make popular houseplants, particularly those that propagate themselves by forming "bulblets" off their fronts which can be cultivated into new plants.
