About Botrychium crenulatum W.H.Wagner
Botrychium crenulatum is a fern species in the Ophioglossaceae family, commonly called scalloped moonwort and dainty moonwort. It is native to North America, ranging from British Columbia through California to Wyoming. It is uncommon across most of its range, and grows incidentally at scattered locations in wet meadows within coniferous forests, and in marshy habitats like swamps. This is a very small plant that grows from an underground caudex, producing just one thin, shiny yellow-green leaf above ground. The leaf reaches a maximum height of approximately 6 centimeters, and is divided into a sterile section and a fertile section. The sterile portion of the leaf has veined, fan-shaped leaflets with crenulate (wrinkly) edges. The fertile portion of the leaf has a very distinct shape, bearing tiny, grape-like clusters of sporangia that the plant uses for reproduction.
