Facts
Blunt-lobed grapefern is an inhabitant of moist and wet forests and swamps. It occurs in all New England states, but is rare throughout. Young, infertile individuals of this and co-occurring grapefern (Botrychium) species may be difficult to tell apart.
Habitat
Forests, swamps, wetland margins (edges of wetlands)
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
