(2598.) C. vulgaris, Fries, var. strictiformis, Bailey, Mem. Toi-r. 

 Bot. Club, I., 74. 



C. vulgaris, Macoun, Cat. IV., 142, in part. 



"Tall and lax (1^ to 2J ft. high), the leaves long and narrow; 

 staminate spike longer peduncled; pistillate spikes looser and often 

 longer than in the species, the perigynia never being so densely packed 

 and usually becoming browner." Lower St. Lawrence. (Fringle, fide 

 Bailey.) Noi-th-west Arm Perry and Point Pleasant, Halifax, KS. ; 

 also at the mouth of Madalene Eiver, Gasp^ Coast, Q. {Macovn.) 



(2599.) C. decidua, Boott; Macoun, Cat. IV., 143. 



The specimens from Eogers Pass, Selkirk Mountains, belong here. 

 It turns out to be a common species in British Columbia, and seems 

 as much at home at 1100 feet altitude as at 6000. Mount Queest, Gold 

 Eange, B.C. (J .M. Macoun.) On the Gold Eange north of Grifiin 

 Lake, alt. 6000 feet ; shore of Shuswap Lake, and along the Thompson 

 to Kamloops, quite common. (^Macoun.) Professor Bailey writes 

 that the present arrangement of specimens under this species is pro- 

 visional. It is the Pacific representative of C. vulgaris. 



(2600.) C. invisa, Bailey; Macoun, Cat. IV., 143. 



Common along Queest Creek, Shuswap Lake, B.C. Alt. 5000 feet. 

 (J. M. Macoun.) Mountains north of GriflSn Lake, Gold Eange, B.C. 

 Alt. 6000; also along Spallumsheen Arm, at Sicamous, B.C. 1200 

 feet alt. 1889. {Macoun.) 



(3195.) C. variabilis, Bailey, Mem. Torr. Bot. Club, I., 18. 



C. aquatilis, Macoun, Cat. IV., 143, in part. 



" Glaucous ; mostly low (2 feet or less high), stout, culm sharply 

 angled, roughish on the angles ; leaves rather broad (as compared with 

 0. stricta, Lam.) ; spikes three or four, short and stout (2 in., or less, 

 long), borne near the top of the culm, erect, the lower one or two con- 

 spicuously attenuated at the base, and appearing clavate, the upper 

 sessile, lower peduncled ; bracts leaf-like and broad, the lower one or 

 two equalling or exceeding the culm ; perigynium small and broadly 

 ovate, abruptly and very short beaked, nerveless, beak entire, green or 

 whitish, conspicuously broader and usually shorter than the obtuse or 

 muticous black scale.'' Old Wives' Lakes, Assiniboia; along Bow 

 Eiver at Calgary, Alberta. {Macoun.)
