It is a deciduous herbaceous plant which produces separate fertile and sterile fronds. The sterile fronds are spreading, 30-150 cm tall and 15-20 cm broad, pinnate, with pinnae 5-10 cm long and 2-2.5 cm broad, deeply lobed (so the fronds are nearly, but not quite, bipinnate). The fertile spore-bearing fronds are erect and shorter, 20-45 cm tall; they become cinnamon-colored, which gives the species its name. The fertile leaves appear first; their green color slowly becomes brown as the season progresses and the spores are dropped. The spore-bearing stems persist after the sterile fronds are killed by frost, until the next season. The spores must develop within a few weeks or fail. Deciduous means temporary or tending to fall off (deriving from the Latin word decidere, to fall off). ... This article is about the plants used in cooking and medicine. ...
