Genus 48. Lygodium Swartz. 
Stems slender, scandent, bearing alternate fronds, which, 
by being dichotomous near the base, appear like two opposite 
fronds. Capsules in spikes along the edge of ordinary or 
modified fronds or part fronds, each capsule separately in the 
axil of an almost marginal infolded involucre, the involucre 
of each capsule imbricating over that next above. Widely 
diffused through Asia, America, Africa and Australia.
