subgenus Botrychium, one of three subgenera of genus Botrychium in North America. Species of subgenus Sceptridium are known as the evergreen grapeferns. In addition to being everggreen, they differ from moonworts (subgenus Botrychium), in their generally larger size …

See the full project: https://www.herbarium.iastate.edu/moonwort-systematics. Botrychium is a genus of ferns.
Botrychium campestre (Iowa moonwort) is known from nine possible populations in Rocky Mountain Region, U.S. Forest Service (Region 2), but only five of these have been verified and observed within the last ten years.
Total range: Botrychium campestre is concentrated in the upper Great Lakes region, western Iowa, and western Minnesota, ranging into Nebraska, North Dakota, Saskatchewan, and Manitoba, with isolated disjunct occurrences known in New York and eastern Canada (Wagner & Wagner 1990). State distribution: Prairie dunewort is known prima-
Botrychium simplex is a small plant, often hidden under grasses and sedges, making it difficult to find. It is also morphologically similar to other species of Botrychium subgenus Botrychium and thus difficult to identify in the field.

This dissertation documents an analysis of genetic diversity in the Botrychium lunaria complex using starch gel enzyme electrophoresis and statistical analysis of genetic relationships. The study resulted in identifying the genetic variation within and between the entities comprising the complex and revealed their geographic distribution.
Botrychium campestre is a small moonwort that was first described as a unique species in 1986. The species ranges across the northern Great Plains, from Iowa and Minnesota on the east, to Alberta and Montana on the west.
Key Words: Botrychium , fem breeding systems, speciation. Botrychium campestre W. H. Wagner & Farrar was described in 1986 (Wagner & Wagner, 1986), based on plants collected in dry prairies in Iowa, and has since been documented from dry, sparsely vegetated habitats such as prairies, dry fields, dunes, and railroad sidings from Glacier National

Linnaeus recognized two species of Botrychium in his 1753 Species Plantarum, B. lunaria and B. virginiana. He placed both in the genus Osmunda. Presl (1845) was the first to use the name Botrychium, recognizing 17 species in his treatment of the genus.
