Botrychium multifidumBotrychium californicumBotrychium coulteriBotrychium matricariaeBotrychium silaifolium Sceptridium multifidum is a fern species in the Ophioglossaceae[1][2] (Adder's tongue family), known by the common names leathery grapefern[3] and leathery moonwort.

It is native to Europe, Asia, and North America including Greenland,[4] where it is widespread and grows in moist areas in many habitat types.

This is a fleshy, leathery plant growing from a small caudex with thin, corky roots.

Unlike most ferns, S. multifidum has contractile roots, which are thought to help anchor the plant in the soil.

[8] In the Pacific Northwest of the USA, Botrychium multifidum grows in sphagnum bogs along the coast, in meadows, and along the margins of mountain lakes and streams.
