Description
Osmunda cinnamomea is a perennial fern that grows as a forb/herb.[2] The leaves are dimorphic and equally broad through much of their length. The basal-most pinnae can be more than 1/2 as long as the largest pinnae. The photosynthetic pinnae have tufts of reddish hairs near the junction with the rachis.[1]
To distinguish from Anchistea virginica, look for a coarser texture, cinnamon tufts of tomentum in the axils of the pinnae, a greenish and fleshy rachis (vs. brown and wiry), and fronds clumped or tufted from a massive, woody, ascending rhizome covered with old petiole bases (vs. fronds borne scattered along a thick, horizontal, creeping rhizome).[1]
Sterile fronds increase their photosynthesis rates in the spring where they level off around 6-8 µmol m-2 s-1. Fertile fronds mature quicker and reached dark respiration rates 2-3 times greater than sterile fronds.[3]
Distribution
This species can be found from Newfoundland and Labrador westward to Ontario and Minnesota, southward to southern Florida and central Texas. It is also in Mexico, southward through Central America to northern South America, in the West Indies, and in eastern Asia.[4]
Ecology
Habitat
O. cinnamomeum occurs in bogs, peatlands, pocosins, wet savannas, floodplains, blackwater stream swamps,[4] swamps, marshes, and open and wet woods.[5] It is also found in disturbed areas including cutover swamps and roadsides.[6]
It increased its presence in response to soil disturbance by heavy silviculture in North Carolina longleaf pine sites.[7] It also increased its biomass in response to soil disturbance by clearcutting and chopping in north Florida flatwoods forests.[8] It has shown regrowth in reestablished native habitat that was disturbed by these practices.[7][8]
Osmundastrum cinnamomeum is an indicator species for the North Florida Wet Flatwoods community type as described in Carr et al. (2010).[9]
Phenology
In the southeastern and mid-Atlantic United States, O. cinnamomeum flowers from March through May.[4][10] On the Florida panhandle, the species has been observed flowering in April.[11]
Fire ecology
Populations of Osmundastrum cinnamomeum have been known to persist through repeated annual burning.[12]
Herbivory and toxicology
White-tailed deer are also reported to consume the fern.[13] The broad-winged hawk will collect sprigs for its nest of several plants and ferns, including O. cinnamomeum. These sprigs are likely used to maintain a clean lining for the nestling.[14]
Conservation, cultivation, and restoration
Cultural use
In China, fronds from O. cinnamomeum are cooked in stir-fry type dishes and consumed by people.[15] Previously in North America, the uncurled fronds were sought for their nutty flavor and would be cooked as a green with some dishes.[16]
