The blunt-lobed grapefern (''Botrychium oneidense'') is a fern species in the Ophioglossaceae family. ==Description== The leaf blades of ''B. oneidense'' are ternately compound. The spores mature in late fall in panicles that rise above the sterile fronds. ==Taxonomy== At first, ''B. oneidense'' was considered a variety of ''B. dissectum'', then a form of it, then possibly a hybrid species. However, after a more detailed study by Wagner in 1961, it was considered its own species.
