“…Sexual reproduction is via bisexual gametophytes (also underground and supported by mycorrhizae) derived from spores released from aboveground leaves. Presumably due to the difficulty of sperm movement underground, new sporophyte production is almost exclusively by intragametophytic self‐fertilization (Soltis and Soltis, 1990; Farrar, 1998; Barker and Hauk, 2003). Consequently, because egg and sperm are derived by mitosis from the same haploid spore, the resulting sporophytes are completely homozygous.…”

We showed that B. acuminatum morphology and genetics are accommodated taxonomically within B. matricariifolium; B. matricariifolium and B. michiganense likely represent hybridization events between related species; and morphotypes within B. matricariifolium likely represent repeated hybridization events between the same two parental species. These hybridizations have resulted in the array of morphotypes observed by field botanists. By helping to identify diagnostic morphological characters, genetic analyses also help us understand and resolve morphological variation observed in the field.

“…Owing in part to their small size (1-15 cm) and production of a single, epigeal leaf per year, moonworts exhibit a remarkable degree of morphological simplicity and possess a limited number of characters for delimiting species and constructing classifications. Using morphological features, Clausen (1938) recognized only six species in subgenus Botrychium, whereas W. H. and F. S. Wagner and others have raised that number to ϳ24 species based on a combination of morphological and cytological studies (F. S. Wagner, 1993;Wagner and Wagner, 1981, 1983a, b, 1986, 1990a, b, 1994Wagner et al, 1984;Farrar and Johnson-Groh, 1991; see Table 1, Figs. Clausen, 1938;Tryon and Tryon, 1982;Wagner and Wagner, 1993).…”

The systematics of Botrychium subgenus Botrychium has been controversial, primarily because reduction in frond size and complexity has limited the number of characters available for discrimination of species. The recognition of many polyploid species has magnified the difficulty of classification because allopolyploids are often morphologically intermediate between their progenitor diploids. In order to evaluate species limits and sectional boundaries, we surveyed and compared 16 of the 24 currently recognized species for isozymic variation. Little or no intrapopulational variation was detected, but the variation present was consistent with the hypothesis that Botrychium species are primarily inbreeding. Interspecific comparisons distinguished six diploid species and provided evidence of molecular differentiation between the cryptic sister species B. lunaria and B. crenulatum. Evidence of possible progenitor/descendant relationships was found for certain diploid/polyploid relationships. Using enzyme bands shared between species, realignment of the sectional assignment of several species is proposed. Anomalous banding patterns in certain individuals suggested that gene silencing or homoeologous chromosome pairing might be operating in B. minganense, B. hesperium, and B. matricariifolium. Isozyme data also showed that some populations of species presumed to be uniformly diploid possessed isozyme patterns typical of polyploids. All available molecular data indicate that members of Botrychium subgenus Botrychium are actively evolving at diploid and polyploid levels.
