Asplenium rhizophyllum plantlet sprouting from the leaf apex of its parent plant. The stipe (the stalk of the leaf, below the blade) is 0.5 to 12 centimetres (0.20 to 4.7 in) long [2] (occasionally up to 15 centimetres (5.9 in) long), and ranges from one-tenth to one and one-half times the length of the blade.
These spores are produced in sporangia that develop on the leaves of the fern's sporophyte. The fern can also reproduce by the division of its rhizomes . On the underside of the blades, the sori (reproductive clusters) are round, discrete, and sunken.
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. The Osmundastrum cinnamomeum fern forms huge clonal colonies in ...

Rattlesnake fern has separate fertile and sterile leaves, when present the sterile leaf arises halfway up the stalk and the fertile leaf exists at the tip. The spores are shed in late spring. Like other ferns rattlesnake fern undergoes alternation of generations and the form described in this article is the sporophyte.
Its leaves are scale-like and appressed, like a mature cedar, and it is glossy and evergreen. It normally grows to a height of about four inches (10 cm), with the spore-bearing strobili held higher. This plant was once widely harvested and sold as Christmas greenery, and populations were widely depleted for this reason.
