Pumice Moonwort
Botrychium pumicola
About Pumice Moonwort (Botrychium pumicola) 0 Nurseries Carry This Plant Pumice moonwort (Botrychium pumicola) is a rare fern of southern Oregon and the Modoc Plateau in northern California. It pertains to the adder's-tongue family (Ophioglossaceae) which may be closely related to the whisk ferns (Psilotaceae). These two families together, according to recent research, share a common ancestor which appears to have diverged early on from the rest of the fern lineage; this probably explains the distinctive morphologies of the members of these two families. There has been speculation that B. pumicola is merely a variety of B. simplex. The two species are indeed closely related, with B. montanum also somewhat closely related, but it has been determined that B. pumicola is in fact a separate species. The range of the plant is restricted to a few counties around Crater Lake in southern Oregon.
