This is the most common grape fern throughout most of its range.

Like other grape ferns, it depends on a mycorrhizal association in the soil.

Others such as the marginal shield fern, grape fern, wood fern, and common polypody are more unusual for this part of the state.

This subclass comprises the ferns commonly known as whisk ferns, grape ferns, adder's-tongues and moonworts.

The flora of the national park is rich, and includes several species red-listed in Estonia such as the Baltic orchid, mezereon and the daisyleaf grape fern; the latter is only found in three locations in Estonia and Karula is one of them.

While some Botrychium species are quite rare, conservation efforts can be difficult.

Botrychium paradoxum is a species of fern known by the common name peculiar moonwort.

A locally rare fern, moonwort, Botrychium lunaria is one of the less common species.

Sceptridium species and their Botrychium synonyms include:

Botrychium simplex (N)

Botrychium in Flora of North America (incl.

Botrychium boreale, commonly called Northern Moonwort, is a species of fern.

Botrychium matricariifolium - The Nature Conservancy.

Botrychium lanceolatum var.

Older fern classifications took a broad circumscription of 'Botrychium' and included the genus in family Ophioglossaceae.

Botrychium pumicola has been found growing with B. lanceolatum and B. simplex.

Botrychium matricariifolium (orth.

Botrychium lunaria Sw.

The only British species is the 'Botrychium lunaria' ('moonwort'), a little plant pretty frequent in dry mountain pastures.

Moonworts are ferns, seedless vascular plants, of the genus Botrychium, sensu stricto.

It is also closely related to the genus Botrypus (the rattlesnake fern, often treated as the subgenus Osmundopteris under Botrychium).

Pumice moonwort (Botrychium pumicola) is a rare fern of southern Oregon and the Modoc Plateau in northern California.

These species (the evergreen grapeferns) have traditionally been placed in the Botrychium subgenus Sceptridium,a name based on the apparent similarity of their sporangia to "little scepters."

Sceptridium is a genus of seedless vascular plants, closely allied to (and often included as a subgenus of) the genus Botrychium (the moonworts and grapeferns).

This plant has long been included in the genus Botrychium, but is unique within the genus because of chromosome number and other signatures, including the inclusion of presumed mistletoe dna within its mitochondria.

Schult., on the lighter areas occurs A. strictum Schrad, the family AIIiaseae, Botrychium lunaria (L.) Sw.

Pease himself named a long list of taxa including species in the Aster, Botrychium, Carex, Agropyron, Potentilla, Houstonia, and Epifagus genera.

The circumscription of Botrychium is disputed between different authors; some botanists include the genera Botrypus and Sceptridium within Botrychium, while others treat them as distinct.

The rattlesnake fern has traditionally been placed in the Botrychium subgenus Osmundopteris, the name of which is based on the species' superficial similarities to the Osmunda genus where it was previously placed.

In addition to having mycoheterotrophic gametophytes, there are a few members of Botrychium that are unique among ferns in having the sporophytes also mycoheterotrophic, producing only small, ephemeral sporophylls that do not photosynthesize.
