A study on speciation of pteridophytes producing underground gametophytes

Methods of isolation of gametophytes from soils and their molecular identification to survey the spatial distribution of underground gametophytes of Botrychium (Ophioglossaceae) were established. I have analyzed the distribution of sporophytes and gametophytes in a native population of the genus in Tsukuba-shi, where three species grow mixed together. The result shows that gametophytes are present in high density where sporophytes are sparse, and gametophytes of multiple species are sometimes spatially very close to each other.
