Monilophyta
Sporangia scattered over the lower surface of the lamina, or 2-3(-4) fused into synangia in the axils of 2-lobed scale-like or leaf-like appendages, or rarely in terminal strobili, then the sporangia hanging from a peltate structure. Monilophyta
Plants growing in soil, mud or epiphytic
Plants not aquatic
Stems not articulate with several-veined leaves or, if the leaves are 1-veined, then not whorled
Sporangia free or many fused laterally or, if 2–4, then borne dorsally in a rosette on the pinnae (Gleicheniaceae)
Sporangia borne on the lower surface or margin of the lamina, usually in definite sori. Vernation circinnate
Sporangia either; non-soral, exindusiate, in oblong or oval patches which are later usually confluent; or else in comb-like lateral or apical sporangiophores
