New England Distribution
Adapted from BONAP data
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: never been documented from the county, but known from the state. May be present. Or, may be restricted to a small area or a habitat (alpine, marsh, etc.), so unlikely found in some counties.
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

Upswept moonwort is rare and widely scattered in North America, mostly in the West and Northwest. In New England it is confined to southwastern Vermont in meadows, quarries and grass-covered roadsides, where it occurs with the closely-related prairie moonwort (Botrychium campestre).

Sometimes Confused With
- Botrychium minganense:
- vegetative portion of leaf conspicuously stalked, with the stalk equal to or greater than the distance between the first and second pair of leaflets, and reproductive portion of leaf on a long stalk that is often longer than vegetative portion (vs. B. ascendens, with the vegetative portion of the leaf short-stalked, the stalk usually shorter the distance between the first and second pair of leaflets, and reproductive portion of leaf on a long stalk that is mostly 0.25-0.5 times as long as the vegetative portion).
- Botrychium campestre:
- rachis of vegetative portion of leaf often relatively broad, up to 0.35 times as broad as the entire portion, and stalk of reproductive portion of leaf shorter than 0.25 times as long as the vegetative portion of leaf (vs. B. ascendens, with rachis of vegetative portion of leaf often relatively narrow, up to 0.25 times as broad as the entire portion, and stalk of reproductive portion of leaf mostly 0.25-0.5 times as long as the vegetative portion of leaf).
