Botrychium lanceolatum is a very small fern, commonly
less than 3 inches tall, although it reportedly can be a bit larger.
The blade is broadly triangular, the fertile portion of the plant
is divided into several more or less equal branches, and the common
stalk is relatively long.
Only variety angustisegmentum is present in our area,
ranging from northeastern U.S. to Ohio and Wisconsin, south in
the appalachians to Tennessee; also in the Rocky Mountains from
Montana to Alberta and British Columbia. It is found only in the
northern half of Wisconsin. This is a small plant found mostly
in our northern mesic forests in rich leaf mold soil of Acer
saccharum (sugar maple) and associates.
