 not S. riiacrostachyus, Lam. 



Tall, slender, 0.6-1.2 m. high, stem leafy. Leaves elongated linear, long- 

 acnminate, 2-4 dm. long, 6-10 mm. wide, those of the involucre 3-5, the largest 

 of them exceeding the inflorescence ; umbel several raye<l, tlie 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 more than one-half their length. 



New York: Lake Pleasant, Hamilton Co. (C. H. Peck); near 

 Schenectady (Wiblje) ; 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 scales, and lonoer, 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.
