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.
