A survey of the Phytogeography of the Arctic American Archipelago 131 
Geographic area. Greenlaad, northern North America, northera and central 
A sia, northern Europé. 
Ås Dahlstedt has described the above mentioned species as forming part of 
the series of the collective T. ceratophomm, I thmk it mRy be best to include tliem 
here under the more comprehensive name. 
204. Taraxacum croceum, Dahlst. 
T. palustre, Taylor, Pl. Balf., ex parte. 
Distribution. [Boothia Felix ?, John Ross (NHM)]; Baffin Land: Cape 
Searle, Taylor (NHM). 
Geographic area. Greenland, arctic North America, northern Europé. 
I think it may be best to use this name, which Dahlstedt himself does now 
look upon as collective, for forms with broad leaves, large calathia, and orange 
flowers, such as are rather common in Greetiland and come nearer in habit to the 
wood and meadow Taraxaca of Europé than the higharctic forms. 
No te to the genus Taraxacum. As the Taraxaca of America, and indeed 
of most parts of the world, are very imperfectly studied as yet, and as, moreover, 
I cannot lay any claim to a closer knowledge of them, I must admit that the 
treatment of them here may be easy enough to find fault with. I have, however, 
tried to make as much use as possible of Dahlstedt's works about the forms in 
question. Handel-Mazetti's monograph I have not bad at hand, and I have not 
thought it necessary to procure it, as I know that he is on many points in opposi- 
tion to the accurate and conscientious taxonomy of Dahlstedt. Several records 
of Taraxaca have not been entered above because no specimens were available to 
show what the author has referred to by the name he has used. The localities for 
this doubtful ramaracww-species are: North Somerset: Port Kennedy, Walker [T. 
officinale var. palustre, Hooker, Exp. Fox); Melville Peninsula: between Repulse 
Bay and Cape Lady Pelly, Rae (Exp., as Leontodon Taraxacum)] Baffin Land: 
Cumberland Gulf, Kumlien (Plants, as T. dens-leonis and T. palustre), Signuia, 
ScHucHERT & White [T. offichiak, Holm, Cat.); Melville Island, M'Clintock [T. 
palustre, Märkham, Life). 
Orepis pygmaea, (Ledeb,). 
Crepis nana, Hooker, App. Parry IL 
Distribution. [Bootliia Felix ?, John Ross (NHM); Mt^lville Peninsula: Five Hawser Bay 
(NHM), Lyon Inlet, Repulse Bay, Parry (ex Hooker, 1. c.)].
