mature fruit uo difference is apparent between plants from Christiania, 

 Norway, and Aroostook Co., Maine. 



The sheath, said by Professor Bailey to be " less conspicuous " in the 

 American plant, is 4 cm. long, by 2.7 mm. wide in one of Macrae's 

 Montreal specimens, fully as conspicuous as in the best developed 

 European material. There is, then, no reason why the American Carex 

 saltuensis, Bailey (C. altocaulis, Britten) with no constant vegetative or 

 morphological character and with a broad range from northern Labrador 

 to the Mackenzie River, northern New England, New York, the Great 

 Lakes and the upper Rocky Mts., should be treated as distinct from C. 

 vaginala of Greenland, northern Europe and Asia. 



Carex capillaris. 



C. capillaris, L. Sp. 977. The Linnaean plant was the low plant 

 of the Scandinavian mountains, described as a span high. This plant, 

 well represented in the Gray Herbarium by European specimens from 

 Andersson, Holmgren, Hoppe, Lehmann, Tuckerman, and others, varies 

 in height from 3 to 25 cm., the spikelets being subapproximate or 

 scarcely remote, the lower at most 2 cm. apart. This dwarf plant 

 occurs likewise in Greenland and northeastern Asia. It has been ex- 

 amined from the following regions in America — Labrador, Dead 

 Islands (J. A. Allen) : Newfoundland, without locality (La Pylaie) ; 

 Middle Arm, Bay of Islands {A. C. Waghome) : Quebec, dry stony 

 ground, near summit — 1,150 m. — Mt. Albert (J. A. Allen): Maine, 

 Mt. Kineo (T. C. Porter et cd) : New Hampshire, Mt. Washington 

 (Wm. Oakes et al): Colorado, Rocky Mts., alt. 3,385 m. {E. L. 

 Greene in Exsicc. Olney) ; South Park (/. Wolfe, no. 1059); Clear 

 Creek, Georgetown, alt. 2,615 m. {H. N. Patterson, no. 144, in part): 

 Utah {S. Watson, no. 1261) : Wyoming, La Plata Mines {E. Nelson, 

 no. 5260). 



Var. elongata, Olney, in herb. & in Rothr. Prelim. Rep. Wheeler 

 PI. 53 (as nomen nudum). Tall, 2 to 6 dm. high, forming loose stools : 

 pistillate spikelets remote, often 6 or 8 cm. apart. — Mossy woods and 

 sphagnum-swamps. Rupert Land, Lake Mistassini {J. M. Macouri) : 

 Newfoundland, Coal River, Bay of Islands (A. C. Waghome, no. 

 24) : Quebec, Ste. Anne des Monts and Little Metis (J. A. Allen) :
