Rhynchospora chalarocephala Fernald & Gale. Common name: Loose-headed Beaksedge. Phenology: Jul-Sep. Habitat: Pine savanna, limesink ponds, and swamps, often weedy and occurring in abundance on wet roadsides and in powerline corridors. Distribution: S. NJ south to c.

Glossary (beta!)

ID notes: Rhynchospora chalarocephala is similar to R. cephalantha var. attenuata but its stems are always erect (vs. leaning or lazy), and the heads are much darker brown and never quite hemispherical. It is similar to R. capitellata but R. chalarocephala occurs mainly in the Coastal Plain and has only one seed per spikelet versus 2-3 in R. capitellata species, which has a generally more northern and inland distribution.

Origin/Endemic status: Endemic
