72 PROCEEDINGS OF THE ACADEMY OF [1887. 



McMinn ; Armstrong, Garher. Common in the mountains, but 

 rare elsewhere. 



39. Carex Magellanica, Lamarck. ( C. irrigua, Smith.) 



Monroe, on the Tuukhannock, Z)?\ Traill Green, June, 1861. 

 Very rare. Its southern limit. Since found (in 1886) in the same 

 neighborhood, by Prof. Dudley, who writes, "The unusually obtuse 

 perigynia more resemble those of the Fuegian specimens figured by 

 Boott than those of any other specimens or figures I have access to." 



40. Carex limosa, L. 



Wayne, Garher ; Monroe, Pocono ; Tioga, Garher ; Bucks, 

 Sellersville, Moyer. Rare. Chiefly in sphagnous bogs on the 

 mountain-plateaus. 



41. Carex virescens, Muhl. 



Monroe, Knipe; Northampton, around Easton ; Bucks, Fretz; 

 Philadelphia, Diffenbaugh ; Delaware, A. H. Smith; Mont- 

 gomery, Diffenhaugh ; Lancaster ; Franklin. Common. 



42. Carex triceps, Michx. 



Northampton; Bucks; Philadelphia; Delaware, Tinicum ; 

 A. H. Smith; Chester, (F1. Cestr.) ; Lancaster; Franklin; 

 Lycoming, A. H. Smith; Tioga, Garher; Blair, Boecking. A 

 common and variable species. 



43. Carex Smithii, Porter. (Olney, Exsicc, fasc. l,no. 28.) 

 Glabrous, except the sheaths of the narrowly-linear leaves ; culms 



slender, erect, 1 to 2 feet high ; fertile spikes 2 to 4, short-cylin- 

 drical, nearly sessile, approximate ; ijerigjoiia globular, contracted 

 to a manifest point, crowded but not imbricated, smooth, a little 

 longer than the ovate, brownish, mucronate scales ; akenes broadly- 

 pyriform, with very short, abrupt, inflexed tips. Chester; Dela- 

 ware, Tinicum and Pusey's Woods, A. H. Smith. 



In shape and appearance, the spikes, perigynia and akenes, and 

 the olive-green hue of the plant, at fir.st sight, suggest C. granularis 

 rather than C. triceps. It is named in honor of Mr. Aubrey H. 

 Smith of Philadelphia. Just beyond our borders, Mr. Canby re- 

 ports it as "very common in fields and woodlands around Wilming- 

 ton, Delaware," and specimens from Gloucester, N. J. were sent me 

 by the late Chas. F. Parker. It is certainly a well-marked variety, 

 if not a distinct species. 



44. Carex longirostris, Torrey, 



Lycoming, near Williamsport, McMiim; Monroe, Water Gap, 

 Xiii/^e; Bucks, Nockamixon Rocks, (rarJer. Rare and local. Its 

 southern limit.
