LYGODIUM

(Redirected from Climbing fern)

'''Lygodium''' ('climbing fern') is a genus of about 40 species of ferns, native to tropical regions across the world, with a few temperate species in eastern Asia and eastern North America. It is the sole genus in the family 'Lygodiaceae', though included in the family Schizaeaceae by some botanists.
They are unusual in that the rachis, or midrib, of the frond is thin, flexible, and long, the frond unrolling with indeterminate growth and the rachis twining around supports, so that each frond forms a distinct vine. The fronds may be from 3-12 m long, depending on the species.
Lygodium is now considered a very problematic invasive species in the southern U.S. Populations of Lygodium have increased more than 12-fold over the past decade--as can be seen on IFAS's SRFer Mapserver.
