 C. vesicaria^ van alpigena^ Fries, Mant ii. 142, v. s., is not to 

 be referred to C, saxatilis. It is highly probable that 

 ^ both this and C. Uymenocarpa are forms of C, rostrata^ 



Stokes, as Lan^e maintains. 



I" 



C. vesicaria^ van dicliroa, Anderss. Cyp. Scand. 18 (1849), is 



evidently also a form of C. rostrata, 

 C. ampullacea^ var. borealis, Lange, FL Groen. ii. 118, v. s- 



Hb. Havn., is not C. compacta^ but is perhaps inseparable 



from the preceding plants. 



The removal of these names from C. compacta {C, mem- 

 branacea, Hook, is C. compacta^ v. s. Hb. Kew.) removes the 

 species from Greenland and renders its characters distinct At 

 the same time, a study of good material indicates that C, rotun- 

 data^ Wahl, (v. s.Hb.Wahl), occurs in America only in Greenland. 

 It is merely a reduced form of C rostrata, Stokes, and need never 

 be confounded with C, compacta. 



45. — Carex monile, Tuckm., is distinguished from all the pre- 

 ceding species by its long and slim spikes which are yellow, 

 its turgid, large, strongly nerved perigynium, which is pro- 

 duced into along and sharply toothed beak, its narrow and 

 sharp scales, and greater size. The var. ohtusisqiiamiSy 

 Bailey, is anomalous, and its position is provisional. 

 Var. Raeana. 



C. Raeana, Boott, Rich. Arc. Exped. ii. 344 (1851), v, s. Hb. 

 Boott; 111. 25, t. 64 (1858). 



Distinguished by its smaller size, much shorter {}% in. or 

 less long) and thinner spikes, and' particularly by the very nar- 

 row and involute leaves. Methye Portage, British America, 

 Richardson. 



Var. COLOR ATA. 



Smaller; spikes shorter than in the species, dark brown; 

 perigynium very much less turgid and shorter beaked; scales 

 shorter and not so sharp. Colorado: Grand Lake, Vasey, 5,849; 

 Leadville, Trelease. I have not the specimens referred to C. 

 monile by Wm. Boott in Bot. Gal. 11. 251 {Bolander 6,21 1), but 

 I suspect that they belong to this variety. Transition to C. sax- 

 atilis var. Grahanti,
