SCIRPUS ATRATUS A SYNONYM OF SCIRPUS PECKII. 
EzRA BRAINERD. 
Scirpus PEckrrt, Britton, (Trans. N. Y. Acad. Sci. XI: 82, 1892) 
was based upon specimens collected by Professor Peck in the Adiron- 
dack region of New York and upon specimens from Connecticut. Dr. 
Britton considered both these collections as representing Scirpus poly- 
phyllus, var. macrostachys, Boeckeler, which he thought worthy of 
specific rank; and as the name “macrostachyus ” had been used 
before in the genus, he called the new species Scirpus Peckit.
