1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 89 



Occurrence. S. Inglefield Gulf: Cape Acland (WETHERILL) ; Port 

 Foulke (HAYES according to DURAND). 



Distribution: East and West Greenland, Arctic American Archi- 

 pelago, Arctic America, Labrador, Canada, Rocky Mountains, Alaska, 

 Ural, Arctic Russia, Spitsbergen, Northern Scandinavia, Bavaria, Scot- 

 land, Iceland. 



Juncaceae. 

 Juncus biglumis, L. 



J. biglumis, SIMMONS, Fl. Ellesm. [J. biglumis, BESSELS, Exp. Pol. 

 Amer. et Amer. Nordpol-Exp.; NATHORST, N. W. Gronl.J. 



Curiously enough, this plant has escaped most collectors, although 

 it can hardly be rare. Only BESSELS, besides NATHORST and myself, 

 has it in his list. In Foulke Fjord I saw it in several places; in swamps, 

 along brooks, etc. as in Ellesmereland. 



Occurrence. S. Ivsugigsok (NATHORST); Inglefield Gulf: Burdin 

 Bay (STEIN); Foulke Fjord, at Etah and elsewhere (1480, 1517). N. Hall 

 Land (BESSELS). 



Luzula arcuata, (WAHLENB.) Sw. var. confusa, (LINDEB.) KJELLM. 



L. arcuata var. confusa, SIMMONS, Fl. Ellesm. ; OSTENFELD, Plantes 

 N. E. Gronl. 



In the case of the Luzulae it is more than usually difficult to make 

 any arrangement of the statements of the different authors, who have 

 more or less confounded two or more species. As shown by my previ- 

 ous revision (1. c., p. 133 136), first there is the L. hyperborea of ROB. 

 BROWN, including two different and well-defined species; further the 

 question about the range of L. arcuata, and so on. Moreover, several 

 authors have believed that they had L. campestris, (L.) DC., also in 

 their material. For my own part, I cannot doubt, that most of the records 

 are referable to L. arcuata var. confusa, which is certainly the most 

 common form here as in Ellesmereland; L. nivalis is undoubtedly a 

 very much rarer plant. My reasons for this opinion are, partly the com- 

 parison of my own observations at Foulke Fjord with my knowledge 

 of the appearance of the two species on the other side of Smith Sound^ 

 partly the inferences that can be drawn from the descriptions and no- 

 tices given in some of the papers, concerning the N. W. Greenland flora. 

 I therefore feel justified in referring all records that do not decidedly
