Lygodium Sw.

Climbing Maidenhair

Greek lygodes - flexible like a willow, referring to the twining stems.

Terrestrial climbing ferns grown for their long, twining fronds. Rhizome long- or short-creeping, branching equally into 2 at each division, the young parts with thick, rigid hairs. Sterile and fertile fronds mostly different. Fronds twining, divided either palmately or with branches along the axis. Fertile segments mostly at the top of the fronds, cut deeply and regularly into spike-like fertile lobes at the ends of veins. Sterile segments with veins mostly free. Sporangia oblong to ovoid, in a double row on marginal spikes. Indusia small, attached along veins, opening forwards.

c. 40 species from tropical to Southern Temperate regions, mostly in Malesia and C America (4 species in Australia.).
