30. Carex vesicaria L., Sp. PI., p. 979. 1753. 

 Type locality. — European. 



Range. — North temperate zone. 



Zone. — Transition mainly rising into the Canadian. 



Specimens examined. — Summit, Dr. Kellogg, July 27, (1870?) ; 

 lower end of Donner Lake, Heller 6938 ; bog along Strawberry Creek, 

 Eldorado County, 5,900 feet, Brainerd 10, 14 ; marshy borders of Lake 

 Andrain, Eldorado County, 7,500 feet, Brainerd 12; Ostrander's 

 meadow above Yosemite, Bolander 6211 ; Lily Lake, Tahoe, 6,600 feet, 

 Smiley 331a; soda springs, head of the Tuolumne River, Brewer 

 1781 ; South Fork of the San Joaquin River, 7,600 feet. Hall and 

 Chandler 625. 



Some of the above specimens have been referred to the many 

 inconstant varieties of this polymorphous species ; in view of what I 

 believe to be the fact — viz., that in any large series of specimens the 

 several named varieties merge inextricably — it has not seemed to me 

 desirable to attempt here their discrimination.
