1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 67 



N. W. Gronl.; MEEHAN, Contr. Greenl.; WETHERILL, List 1894; OSTEN- 

 FELD, Fl. pi. Gape York]. 



Very common, but abundant only in manured places such as rook- 

 eries and old places of habitation. Some individuals may be branched, 

 but more than a single flower is rarely developed. 



Occurrence. S. Cape York (STEIN); Ivsugigsok (NATHORST); Wol- 

 stenholme Sound (INGLEFIELD); Umanak and Agpa (BALLE), Inglefield 

 Gulf: Northumberland Island (STEIN, WETHERILL), Cape Acland (WETH- 

 ERILL), Verhoeff Nunatak (MEEHAN); Foulke Fjord: Reindeer Point, Etah, 

 etc. (202, STEIN, HART), Port Foulke (HAYES); up to 80 (KANE) and 

 doubtless also to the north. 



Saxifraga rivularis, L. 



S. rivularis, SIMMONS, Fl. Ellesm. ; OSTENFELD, Plantes N. E. Gronl. 

 [S. rivularis, DURAND, Enum. pi. Smith S. ; HART, Bot. Br. Pol. Exp. ; 

 NATHORST, N. W. Gronl.]. 



Besides the common, taller, and often branched form, I also found 

 the same small form that I have mentioned from Ellesmereland (1. c., 

 p. 76), and according to Mr. HOLM the var. purpurascens, LANGE, is 

 collected by STEIN. 



Occurrence. S. Cape York (HART, STEIN); Ivsugigsok (NATHORST); 

 Inglefield Gulf: Northumberland Island (STEIN), Netlik (HAYES); Foulke 

 Fjord (HART), in several places near Reindeer Point (238, 248, 1488). 



Cruciferae. 

 Hesperis Pallasii, (PURSH.) TORR. & GRAY. 



H. Pallasii, SIMMONS, Fl. Ellesm. [H. Pallasii, DURAND, Enum. pi. 

 Smith S.; HART, Bot. Br. Pol. Exp.; MEEHAN, Contr. Greenl.]. 



This plant also belongs to the little group of decidedly american 

 immigrants in N. W. Greenland. It seems to be somewhat more spread 

 there than was known when NATHORST made his revision of the flora 

 of that area (N. W. Gronl.). At Etah it grew fairly abundantly in the 

 gravel ledges, and the plants were for the most part luxuriant, having 

 several stems. They had ripe pods in abundance when collected about 

 the midle of August. 



Occurrence. S. Cape York or M'Cormick Bay in Inglefield Gulf? 

 (BuRK according to MEEHAN); Netlik (HAYES); Foulke Fjord, at Etah 

 (HART, 240, 1474); at Mary Minturn River (KANE). N. Lafayette Bay 

 in Washington Land (MORTON according to KANE).
