GENUS INDEX

GENUS CODE: THELY2
GENUS SCIENTIFIC: Thelypteris
GENUS AUTHORITY: Schmidel
GENUS COMMON: Maiden fern
GENUS SUMMARY: A genus of 2-4 species, perennial herbs, cirumboreal in distribution (with several varieties) and slso with a Southern Hemisphere member. Often in the past considered a large genus (with over 800 species), clearly warranting segregation, but a consensus has been slow to coalesce; we now seem ready for at least a preliminary approach to genera in Thelypteridaceae, as reflected in this treatment of Thelypteris and segregates. Our species fall into several disparate groups, here recognized as genera.
