Description
Paspalum setaceum is a perennial graminoid of the Poaceeae family that is native to North America.[1] It has a tufted growth that originates from short rhizomes. The culms are 1-8 dm tall with glabrous nodes and internodes. The leaves are basal and cauline. The blades are 4 dm long and 12 mm wide, glabrous or pubescent, with scaberulous and ciliate margins. The sheaths are glabrous or pubescent, with scarious and ciliate margins. Ligules are membranous, ciliate apically, and 2-6 mm long. There are 1-2 racemes which are terminal and axillary, 4-14 cm long, with scaberulous pedicels that are 0.5-1.2 mm long.[4]
Paspalum setaceum does not have specialized underground storage units apart from its rhizomes.[5] Diaz-Toribio and Putz (2021) recorded this species to have an non-structural carbohydrate concentration of 39.7 mg/g (ranking 81 out of 100 species studied) and water content of 55.6% (ranking 33out of 100 species studied).[5]
According to Diaz-Torbio and Putz (2021), Paspalum setaceum has rhizomes with a below-ground to above-ground biomass ratio of 0.356 and nonstructural carbohydrate concentration of 39.7 mg g-1.[6]
Distribution
P. setaceum is found throughout the majority of the continental United States, excepting western states North Dakota, Wyoming, Utah, Nevada, Idaho, Washington, Oregon, and California. It is also found in Ontario, Canada.[1]
Paspalum setaceum var. psammophilum is endemic to an area from southeastern Massachusetts to southern New Jersey and adjacent Delmarva Peninsula.[7]
Ecology
Habitat
Habitats include sandhills, savannas, and other dry soils. Other varieties can be found in grasslands, pine flatwoods, pine savannas, old fields, and other fields.[4] Specimens have been collected from habitats such as dry sand of grass clearing, a wooded ridge with sandy loam, open wet pine flatwoods and mixed hardwood swamps, floodplain forest, shade near lakes, coastal hammock, pine flatwoods, fire run in a flatwood, botanical gardens, sandhill, and waste ground.[8]
P. setaceum increased its occurrence in response to roller chopping in south Florida.[9] It increased its frequency in response to clearcutting and chopping in north Florida flatwoods.[10] It has also increased its occurrence in response to agriculture in South Carolina longleaf pine.[11] Additionally, this species has increased its foliar cover in response to soil disturbance by clearcutting and roller chopping in north Florida.[12] It has shown regrowth in reestablished native habitat that was disturbed by these practices, making it a post-agricultural woodland indicator species.[9][10][11][12]
This species has had mixed responses to chopping, disking, fertilizing, and bedding in south Florida prairie. It either increased its biomass or was unaffected by these practices.[13]
Paspalum setaceum is frequent and abundant in the Peninsula Xeric Sandhills, North Florida Longleaf Woodlands, North Florida Subxeric Sandhills, and Central Florida Flatwoods/Prairies community types as described in Carr et al. (2010).[14]
Phenology
P. setaceum has been observed flowering in June.[15]
Seed dispersal
This species is thought to be dispersed by gravity.[16] It has been found that gopher tortoises can disperse the seeds of the grass through their scat. The germination success of these partially digested seeds is much lower than those that are not.[17]
Fire ecology
Populations of Paspalum setaceum have been known to persist through repeated annual burns.[18][19][20]
Herbivory and toxicology
P. setaceum provides forage for livestock and deer in Texas.[1] This species has been known to hold up well to and increase in response to heavy grazing by cattle.[21] Birds have been observed to eat the seeds.[1]
