Asplenium ruprechtii

Asplenium ruprechtii, which goes by the common name Asian walking fern, is a rare, hardy, low-lying fern native to East Asia. It is a close relative of Asplenium rhizophyllum (syn: Camptosorus rhizophyllus) which is found in North America and also goes by the common name of walking fern. The species should not be confused with Asplenium sibiricum which is a synonym of Diplazium sibiricum.
