Narrow Triangle Moonwort (Botrychium angustisegmentum (Pease & A.H.Moore) Fernald)
Also known as narrow triangle moonwort; also classified as Botrychium lanceolatum var. angustisegmentum Pease & A.H.Moore, Botrychium lanceolatum subsp. angustisegmentum (Pease & A.H.Moore) R.T.Clausen.
A number of sources, including USDA PLANTS, BONAP, and FNA, lump this in with lanceleaf grapefern (Botrychium lanceolatum), as var. or subsp. angustisegmentum. We separate them per the treatment of POWO.

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
This species is also native to Canada; we have yet to build this portion of its map.
