pistilliferis ; fructibus ovatis lanceolatis convexo-concavis subu- 

 latis subbiden talis, squama acuta ovata paulo longioribus. 



Culm fifteen to twenty eight inches high, erect, leafy towards 

 the base, three-sided, striate, scabrous ; leaves flat, linear, striate, 

 shorter than the culm, shorter below, and sheathing ; spike two 

 inches long and composed of numerous spikelets, fifteen to twenty 

 each, ovate and sessile, simple pistillate below, sometimes with 

 few staminate flowers, sometimes several of the upper spikelets 

 mostly or entirely staminate, the lower half commonly more 

 abundantly pistillate, sometimes all mostly pistillate ; stigmas 

 two ; staminate scale lanceolate ; scale of the fruit ovate, acute, 

 rather broad, and a little shorter than the fruit ; light green, stiff 

 plant. 



This Carex is near C. intermedia, Gooden. ; but it differs from 

 it in not having compound and compressed spikelets, and in hav- 

 ing smaller fruit, and pistillate scale much shorter and less broad. 

 From C. marcida^ Boott, it differs in the lower spikelets, and in 

 fruit, which is much shorter and less lanceolate. 



Found by Dr. S. P. Sartwell in Junius, Seneca county, N. Y., 

 after whom it is named, with the " genitive termination," and 

 " in accordance with well established rules of botanical nomen- 

 clature."

Dioica ; spica pistillifera composita maxima dense ovato-capi- 

 tata distigmatica inferne substaminifera ; fructibus ovato-lanceo- 

 iatis maximis compressis nervosis glabris bicuspidatis margine 

 serrulatis, squama ovata longo-cuspidata paulo longioribus. 



Culm eight to twelve inches high, angular, large, leafy ; leaves 

 sheathing, numerous, flat, linear-lanceolate, longer than the culm, 

 lower leaves short ; staminate spike large and thick ; dioecious, 

 and stigmas two ; fertile spike single, large, ovate, oblong, and 

 composed of many small spikelets compacted into a dense head, 

 sometimes staminate below ; fruit large and long lanceolate ; plant 

 yellowish green. 



This is a very singular and strongly marked species, supposed 

 to inhabit Siberia by Sprengel in Systema Vegetabilium, Ed. 16; 

 Dr. Boott credits it the Northwest coast, and Mr. Nuttall collected 

 it in his tour across the Rocky Mountains, and through the kind- 

 ness of Prof Torrey I have been permitted to examine it.
