DA59FC37FF9CFFDDFF6C9F689512D040.taxon	discussion	Notes: The hybrids produced by Athyrium filix-femina (Linnaeus 1753: 1090) Roth (1800: 65) and Athyrium distentifolium Tausch ex Opiz (1820: 14) include diploid, triploid, which normally occur as clones of very different size, and the nothospecies published is a diploid. The hybrids occur in shady places of deciduous and coniferous mountain forests, at elevations of 840 m to ca. 1650 m (Schneller & Rasbach 1984, Rasbach et al. 1991).	en	Wan, Xia, Zhang, Li-Bing (2022): Three new fern names of hybrid genera and four new combinations in Athyriaceae, Osmundaceae, and Thelypteridaceae.

DA59FC37FF9CFFDDFF6C9B0C952CD4C1.taxon	discussion	Notes: This nothospecies is a hybrid between Claytosmunda claytoniana (Linnaeus 1753: 1066) Metzgar & Rouhan in PPG I (2016: 594) and Osmunda regalis var. spectabilis (Willdenow 1810: 98) A. Gray (1856: 600). It has intermediate morphology of the parents, such as fertile fronds, segment size, vein branching, and segment margins. Although its parents occur together in a large area, mature hybrids are difficult to find due to its rarity. Perhaps they are incompatible with other plants, or there are strong incompatibility barriers between the parents (Tryon 1940, Wagner et al. 1978).	en	Wan, Xia, Zhang, Li-Bing (2022): Three new fern names of hybrid genera and four new combinations in Athyriaceae, Osmundaceae, and Thelypteridaceae.
