even probable, that the latter plant may hide under some of the state- 

 ments about P. pulchella and P. nivea. At all events P. pulchella 

 seems to be rather a rare plant in N. W. Greenland. Besides my own 

 specimens which represent a form from rather dry localities and which 

 somewhat resemble the corresponding form of P. rubricaulis, I have 

 only seen specimens collected by NATHORST (also nearly approaching 

 P. rubricaulis) and by HART. The P. pulchella of DURAND, Enum. pi., 

 according to the description must be P. rubricaulis, and the same per- 

 haps is the case with the Port Foulke plant of HAYES. 



Occurrence. S. Ivsugigsok (NATHORST); Port Foulke (HAYES,?); 

 Foulke Fjord, on a sandy beach near Reindeer Point (1529).

 [P. rubricaulis, OSTENFELD, Fl. pi. Cape York; P. nivea var., NATHORST, 

 N. W. Gronl.; HART, Bot. Br. Pol. Exp., ex p. ?; P. pulchella, DURAND, 

 PI. Kan. ?]. 



This species is probably more common in our area than is the 

 preceding one, but as already mentioned, it has always been overlooked 

 and confounded with others. At Etah it was not rare in the grassy 

 and gravelly slopes. I am very much inclined to think that the P. pul- 

 chella of DURAND is really the present species. His description clearly 

 shows that he has not had the real P. pulchella in front of him for 

 he says: "Flower rather large, of a deep yellow colour; petals obcord- 

 ate, longer than the calyx". 



Occurrence. S. Ivsugigsok (NATHORST); Umanak and Agpa in 

 Wolstenholme Sound (BALLE); Etah in Foulke Fjord (221, 1461, 1882); 

 Rensselaer Bay and Mary Minturn River ? (KANE). 



Potentate anserina, L. 



As previously mentioned (SIMMONS, Fl. Ellesm., p. 54), there are no 

 specimens to confirm HART'S statement (Bot. Br. Pol. Exp., p. 29) about 

 the occurrence of this species at Foulke Fjord, and as it has not been 

 found so far north by other collectors, it must be excluded from the 

 flora of our area. 



Potentate nivea, L.
