Description
R. globularis is a annual/perennial graminoid of the Cyperaceae family that is native to North America.[1]
Distribution
Found largely throughout the southeastern United States, R. globularis is specifically in Florida, Georgia, South Carolina, North Carolina, Virginia, Maryland, New Jersey, New York, Tennessee, Alabama, Mississippi, Louisiana, Texas, Arkansas, as well as in the western state California.[1]
Ecology
Habitat
R. globularis has been found in marsh shorelines, hardwood hammocks, ditches, prairies, cypress domes, scrub oak sand ridges, savannahs, floodplains, wetlands, and pine flatwoods.[2] It is also found in disturbed areas including logging road margins, along roadsides, pond trails, grassy pastures, and railroad ditches. [2]
Associated species: R. chapmanii, Senecio anonymus, Hedeoma hispida, Rhynchospora globularis, Polygala, Rhexia, Xyris, Scleria, and Sarracenia, Ilex, Myrica, Nyssa, and Rhynchospora spp..[2]
Additionally, it is an indicator species for the Calcareous Savannas community type as described in Carr et al. (2010).[3]
Phenology
R. globularis has been observed flowering in January and March through September with peak inflorescence in May.[4]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates.[5]
Fire ecology
Populations of Rhynchospora globularis have been known to persist through repeated annual burning.[6]
Conservation, cultivation, and restoration
R. globularis is classified as endangered in Maryland, Michigan, New Jersey, Ohio, and is of special concern in Kentucky.[1]
