50 H. G. SIMMONS. [SEC. ARCT. EXP. FRAM 



This species, principally greenlandic, has curiously enough, never 

 been mentioned from N. W. Greenland before I used the name in my 

 Prel. Rep., although in a wrong sense, as I had not then subjected my 

 Taraxaca to a closer study. In fact, the real T. phymatocarpum is 

 not present in my collection from Foulke Fjord, but DAHLSTEDT has 

 found it hiding under other names in collections from our area. 



Occurrence. S. Ivsugigsok (NATHORST); Whale Sound, Netiulumi 

 ( WETHERILL). HOLM, in his list of the STEIN collection, has used for a plant 

 from Northumberland Island the same name (T. off. var. lividum) as 

 FERNALD in WETHERILL, List 1894; perhaps this statement also may be 

 referable to the species here in question. 



Taraxacum arctogenum, DAHLST. 



T. arctogenum, DAHLSTEDT, Tarax. ceratoph., 1906; T. officinole, 

 NATHORST, N. W. Gronl., ex p.; T. phymatocarpum, SIMMONS, Prel. 

 Rep. et Bot. Arb., ex p.

When I published my first reports of the botany of the expedition, 

 I confounded this species with the common Ellesmereland plant, i. e. T. 

 hyparcticum; but later on I found that it came near to T. ceratophorum, 

 which was already stated as a Greenland plant, although not mentioned 

 from the north-western parts. Dr. DAHLSTEDT, however, has founded a 

 new species on my material. 



Occurrence. S. Ivsugigsok (NATHORST); Foulke Fjord, abundant in 

 the gravelly and clayish slopes beneath Etah (198, 1473). Perhaps also 

 the T. phymatocarpum from Etah in HOLM'S list of the STEIN collec- 

 tion may be referred here. Mr. HOLM hat determined those plants be- 

 fore DAHLSTEDT'S treatises were published. 



Distribution. Danish West Greenland (known from a single lo- 

 cality at 68 35'). 



Arnica ulpina, (L.) OLIN. 



A. alpinci, SIMMONS, Fl. Eilesm. [A. alpina, MEEHAN, Contr. Greenl.; 

 WETHERILL, List 1894]. 



This species was first brought home from "near Smith's Sound, 

 78" by KANE, but as it was not found by subsequent expeditions, 

 NATHORST enters it in his list (N. W. Gronl.) as doubtful. Later expedi- 

 tions have, however, found it in several places.
