Deciduous perennial, 3-15 cm tall.
The only North American collections of Botrychium boreale Milde have been recently collected in Kootenay National Park, SE BC (W.H. Wagner, pers. comm.). It is difficult to separate from B. pinnatum, but the lowermost pinnae have shallow, narrow sinuses (they are wide and deep in B. pinnatum).
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
