Chromosome numbers of some northern New Jersey carices [Carex]

Carex is the largest genus of vascular plants in northeastern North America with 214 species treated in Gleason and Cronquist (1963). This paper will add some useful data to the knowledge of the group by reporting chromosome numbers taken from samples of the genus found growing in northern New Jersey. All chromosome counts are taken from anther squashes using the procedure of Cooperrider and Morrison (1967). Nomenclature follows that in Gleason and Cronquist (1963) except for Carex emmonsii Dewey.
