Kingdom Plantae   >   Division Pteridophyta   >   Class Psilotopsida   >   Order Ophioglossales   >   Family Ophioglossaceae   >   Genus Ophioglossum   

Status:

Most sources treat this species (Southern Adder’s-Tongue) in North America as a synonym of the European Ophioglossum vulgatum. However, Weakley (2020, Flora Southeastern US) prefers the name Ophioglossum pycnostichum. Hopefully future studies of this species will uncover the relationship between North American and European populations.

There are 60 records in the project database.
