Description
C. polystachyos is an annual/perennial graminoid of the Cyperaceae family.[1] Leaves are simple and alternate, with linear shape and parallel leaf venation. Flowers are unisexual and bisexual, and developing fruit is an achene. Flowers are borne in a single dense cluster that have linear-ovately shaped spikelets, and 2 stamens. Fruit is dark to light brown in color and develops between summer and early fall. Roots are fibrous, and overall plant can reach a height between 1 and 3 feet.[3]
Distribution
C. polystachyos is pantropical can be found along the southeastern coast from Texas to Maine, Hawaii, the Pacific Belt, Puerto Rico, and the U.S. Virgin Islands.[1][2]
Ecology
Habitat
C. polystachyos proliferates in low fields, ditches and marshes, as well as warm temperate environments. [2] It is also present in sandy areas. [4] It is listed as a facultative wetland species, meaning it commonly can be found in wetlands but can also sometimes be found in non-wetlands.[1]
Phenology
C. polystachyos has been observed to flower between June and September.[5] It is also known to flower in October additionally.[2]
Fire ecology
C. polystachyos is not fire resistant, and has no fire tolerance.[1] However, it is commonly found in calcareous savannas that are fire dependent ecosystems.[6] A study also found seeds of C. polystachyos to persist in the seed bank after fire disturbance.[7]
Use by animals
This sedge is not known to have any foraging value.[8]
Conservation and Management
C. polystachyos is listed as endangered by the New Jersey Department of Environmental Protection and Energy Office of Natural Lands Management, and as extirpated by the Pennsylvania Department of Conservation and Natural Resources. [1]
