Rhynchospora setosa

Rhynchospora setosa ( Cyperaceae ), a new species from southern Mississippi. Primary authors:Patrick D. McMillan and Richard J. LeBlond

This distinctive Rhynchospora in sect. Chapmaniae (Gale) Kükenthal is described from a pitcher-plant seepage slope in a longleaf pine forest in Jackson Co., Mississippi. The plant is very similar to R. chapmanii M.A. Curtis in sect. Chapmaniae and is likely closely related to it ( McMillan 2007). Section Chapmaniae is currently treated as a member of Rhynchospora subgenus Diplostylae Benth. in LeBlond (2023), with “ Rhynchospora species 2 ” as a nomenclatural placeholder for R. setosa . In McMillan, R. setosa is referred to as “ Rhynchospora sp.1 .”
