west to Minnesota and Arkansas. 
34. Scirpus Peckii, n. sp. 
S. polyphyllus, var. macrostachys, Beeck1., Linnea, xxxvi, 731 (1870), ex deserip. 
not S. macrostachyus, Lam. 
Tall, slender, 0.6-1.2 m. high, stem leafy. Leaves elongated linear, long- 
acuminate, 2-4 dm. long, 6-10 mm. wide, those of the involucre 3-5, the largest 
of them exceeding the inflorescence ; umbel several rayed, the rays slender, 
1-6 cm. long; spikes 4-8 mm. long, cylindric, capitate in clusters of 2-10, 
appearing umbellulate in age by the falling away of the lower scales; scales 
dark brown, ovate, carinate, mucronate ; nut trigonous, 0.5 mm. long, oblong, 
acute at each end, twice as long as thick, slender-beaked; style 3-cleft ; bris- 
tles 4-6, downwardly barbed mere than one-half their length. 
New York: Lake Pleasant, Hamilton Co. (C. H. Peck); near 
Schenectady (Wibbe); West Albany (P. A. Puissant). Connecti- 
cut: Middletown (Barrett). Also an old specimen in Herb. Torrey, 
with no definite locality. 
Nearest to S. radicans, Schk., of continental Europe. That species 
differs, however, in its umbellulate, ovate, shorter spikelets, broader 
and less mucronate seales, and longer, twisted, smooth bristles. I 
take pleasure in associating with this interesting plant the name of 
the distinguished State Botanist of New York, who has done so 
much in making known the flora of our Commonwealth.
