Varieties

There are three to four varietiesVariety (biology)

In botanical nomenclature, variety is a rank below that of species: As such, it gets a ternary name....
 as traditionally construed:
  • Osmunda regalis var. regalis. Europe, Africa, southwest Asia. Sterile fronds to 160 cm tall.
  • Osmunda regalis var. panigrahiana R.D.Dixit. Southern Asia (India).
  • Osmunda regalis var. brasiliensis (Hook. & Grev.) Pic. Serm. Tropical regions of Central and South America; treated as a synonym of var. spectabilis by some authors.
  • Osmunda regalis var. spectabilis (Willdenow) A.Gray. Eastern North America. Sterile fronds to 100 cm tall.


There are two very similar species, Osmunda lancea and Osmunda japonica. Recent genetic analysis (Metzgar et al, 2008) has shown that the New World varieties are in a clade that is sister to the Old World varieties of Osmunda regalis. If this is true, then O. lancea and O. japonica should either be regarded as varieties of O. regalis, or, conversely, O. regalis var. spectabilis should be regarded as a separate species, Osmunda spectabilis WilldenowCarl Ludwig Willdenow
