1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N..W. GREENLAND. 67 
N. W. Gronl.; Meeuan, Contr. Greenl.; Werneritt, List 1894; Osten- 
FELD, Fl. pl. Cape 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 (Srery); Ivsugigsok (Natuorst); Wol- 
stenholme Sound (InGLerte.p): Umanak and Agpa (Battie), Inglefield 
Gulf: Northumberland Island (Srew, Werxerm), Cape Acland (WertH- 
ERILL), Verhoeff Nunatak (Mrenan); Foulke F jord: Reindeer Point, Etah, 
etc. (202, Srem, Hart), Port Foulke (Hayes); up to 80° (Kang) and 
doubtless also to the north. 
Saxifraga rivularis, L. 
S. rivularis, Simmons, Fl. Ellesm.; Ostenretp, Plantes N. E. Gronl. 
[S. rivularis, Duranp, Enum. pl. Smith S.; Harv, Bot. Br. Pol. Exp.; 
Natuorst, N. W. Grénl.]. 
Besides the common, taller, and often branched form, I also found 
the same small form that I have mentioned from Ellesmereland (I. c., 
p. 76), and according to Mr. Hotm the var. purpurascens, Lance, is 
collected by Stern. 
Occurrence. S.Cape York (Hart, Stern); Ivsugigsok (NaTHORST); 
Inglefield Gulf: Northumberland Island (Stet), Netlik (Hayes); Foulke 
Fjord (Hart), in several places near Reindeer Point (238, 248, 1488). 
Cruciferae. 
Hesperis Pallasii, (Pursu.) Torr. & Gray. 
H. Pallasii, Simmons, Fl. Ellesm. [H. Pallasii, Duranp, Enum. pl. 
Smith S.; Hart, Bot. Br. Pol. Exp.; Meruan, 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 Natuorst 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 Meewan); Netlik (Hayes); Foulke Fjord, at Etah 
(Hart, 240, 1474); at Mary Minturn River (Kang). N. Lafayette Bay 
in Washington Land (Morton according to Kang).
