Plants terrestrial. Stems branched, slender. Leaves often more than several meters, 2-pinnate or more divided, climbing by means of twining rachis; fertile pinnae borne toward apex of fertile leaves. Blades of short, alternate primary pinnae. Pinnules ± entire to palmately or pinnately lobed; fertile and sterile pinnae similar or fertile pinnae greatly contracted.
Distribution
Nearly worldwide, mostly tropical regions, a few species in temperate regions, North America, Asia in Japan, s Africa, Pacific Islands in New Zealand.
Discussion
Species ca. 40 (3 in the flora).
