Already during the expedition, I was in no doubt about the fact that 
all the statements in literature about the Taraxacum-forms of N. W. 
Greenland and the adjacent countries, must be based entirely upon wrong 
determinations ; the plants may be called 7. officinale, T. palustre, T. 
Dens Leonis, or any other name. The little I have seen of the collec- 
tions made by others from the area here in question, has further con- 
firmed my opinion, and I can only regret the impossibility of examining 
the collections from most of the american expeditions. When Dr. DaHt- 
stepT began his researches in arctic Taraxaca, now published in his 
treatises Stud. arkt. Tarax., and Tarax. ceratoph., he also found that 
the above names were generally used for plants representing new and 
hitherto undescribed species. But it has been impossible for him also 
to control the american authors; and it must still be left an open 
question what they meant, except in a few cases where specimens have 
been accessible, or where at least a guess is possible. 
The species here in question has been examined by DAHLSTEDT in 
my collection; but about its occurrence in other parts of the area than 
that where I found it, only conjectures are possible. 
Occurrence. This species is as yet only known with certainty ina 
few individuals from a single locality in N. W. Greenland, Etah in Foulke 
Fjord (4268, 4269). DanisTept found them mixed in my Taraxacum 
collection from that point which, for the most part, represented 7. arcto- 
genum Dautst. It is, however, rather probable that the 7. palustre 
which Harr (Bot. Br. Pol. Exp.) speaks of as a form of T. Dens Leonis, 
occurring in Foulke Fjord, is the same.  T. palustre is also mentioned 
by Duranp (Enum. Pl. Smith S.) as collected at Netlik by Hayes and 
by Kane at Bedevilled Reach (Enum. Pl.); but without seeing the spe- 
cimens it is impossible to form any opinion about the plant that is meant.
