In 2008, the Tatton Park Biennale commissioned Phillips to make an installation titled " The Walking Ferns ", which consisted of a herd of robotic ferns walking in the Victorian Rose Garden.

In 1974, John Mickel published " Asplenosorus gravesii " as a new combination for the species to allow the continued recognition of the genus " Camptosorus " for the walking ferns.

It is a close relative of " Asplenium ruprechtii " ( syn : " Camptosorus sibiricus " ) which is found in East Asia and also goes by the common name of " walking fern ".

A similar plant collected from limestone in Shepherdstown, West Virginia could have originated from the same parents, from an unreduced ( diploid ) gametophyte of Scott's spleenwort crossed with walking fern, or from an unreduced walking fern gametophyte crossed with ebony spleenwort.

It is believed to have originated by chromosome doubling in a hybrid between walking fern and mountain spleenwort ( " Asplenium montanum " ), producing a fertile tetraploid, a phenomenon known as alloploidy; however, the hypothesized parental hybrid has never been located.
19.
It is intermediate in morphology between the parent species : while its leaf blades are long and tapering like that of walking fern, the influence of mountain spleenwort means that the blades are lobed, rather than whole . " A . pinnatifidum " can itself form sterile hybrids with several other spleenworts.
20.
Because the latter is a tetraploid hybrid between " A . montanum " and walking fern ( " A . rhizophyllum " ), half of the chromosomes it contributed to " A . ?trudellii " pair with those contributed by " A . montanum " and half do not.
