Description
F. squarrosa is a native perennial graminoid that is a member of the Cyperaceae family [1]. Species in this family grow reproductive units in the form of spikelets, which contain highly simplified flowers [2]. F. squarrosa has alternate simple leaves shaped linearly, and contains a fibrous root structure like most Monocots. The inflorescence is a spikelet, like other grasses, and the perianth contains bristles.[3]
Distribution
The species can be found in the Southeast United States, ranging from Texas to Virginia, as well as in the Northeast in Maryland, New Jersey, and New York [1]. It becomes more rare in communities located in Tennessee, Delaware, and New Jersey [4]. Although it is mainly distributed along the southeastern coastal plain, it is less strictly limited than other species.[5]
Ecology
Habitat
F. squarrosa can be found in mesic communities, including sphagnous bogs, [6] and can be found infrequently in pine-palmetto communities and wet prairies [7]. As well, F. squarrosa is present in habitats ranging from wet sandy loams of roadside depressions and other wet loamy sand disturbed sites. [8] It is listed by the USDA Natural Resources Conservation Service as an obligate wetland species, where it only occurs in wetland habitats.[1] As well, F. squarrosa is considered an indicator species of panhandle seepage savannas in north Florida.[9]
Associated species - Eleocharis tuberculosa, Gentiana saponaria, Bartonia paniculata, Platanthera cristata, Pyrus arbutifolia, and Viburnum nudum [6].
Phenology
This species generally flowers from July until October.[5] This bloom time also denotes the fruiting period for F. squrrosa.[3] Flowering time ranges continuously from August until October, while fruit development has been seen in the months of May and October. [8]
Fire ecology
Sphagnous bogs and other similar communities are fire dependent due to their high acidity, which makes F. squarrosa dependent on fire frequency [10].
Conservation and Management
This species is listed as threatened by the Michigan Department of Natural Resources, Natural Features Inventory, and is listed as a species of special concern by the Tennessee Department of Environment and Conservation, Natural Heritage Program.[1]
