Blotiella Hieronymi
''Blotiella'' is a genus of ferns in the family Dennstaedtiaceae described as a genus in 1962.Christenhusz ''et al.'' "A linear sequence of extant families and genera of lycophytes and ferns"
''Phytotaxa'' 19: 7-54. 18 Feb. 2011 The genus was named in honor of Marie Laure Tardieu-Blot (1902–1998), who was a French

Rolla Milton Tryon
Rolla Milton Tryon Jr. (August 26, 1916 – August 20, 2001) was an American botanist who specialized in the systematics and evolution of ferns and other spore-dispersed plants (pteridology). His particular focus and interest lay in two areas, historical biogeography of ferns and the taxonomy of tropical American ferns. Biography Rolla Milton Tryon Jr. was born August 26, 1916 in Chicago. His father was an American history and education professor at the University of Chicago. Tryon's first scientific paper was published in 1934 (at the age of 18) on the ferns in Chesterton, Indiana where his family’s summer cottage was located. In 1935, he received his A.A. degree and in 1937 his B.S., both from the University of Chicago. He enrolled in the University of Wisconsin for a Ph.M., graduating in 1938. Then, at Harvard, earning he earned both his M.S. in 1940 and Ph.D. in 1941 working with Merritt Lyndon Fernald and Charles Alfred Weatherby on ferns in the genera ''Pteridium'' and ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ...

Dennstaedtiaceae
Dennstaedtiaceae is one of fifteen families in the order Polypodiales, the most derived families within monilophytes (ferns). It comprises 10 genera with ca 240 known species, including one of the world's most abundant ferns, ''Pteridium aquilinum'' (bracken). Members of the order generally have large, highly divided leaves and have either small, round intramarginal sori with cup-shaped indusia (e.g. ''Dennstaedtia'') or linear marginal sori with a false indusium formed from the reflexed leaf margin (e.g. ''Pteridium''). The morphological diversity among members of the order has confused past taxonomy, but recent molecular studies have supported the monophyly of the order and the family.Smith, A. R., K. M. Pryer, et al. (2006). "A classification for extant ferns." Taxon 55(3): 705-731 The reclassification of Dennstaedtiaceae and the rest of the monilophytes was published in 2006, so most of the available literature is not updated.
