Erigeron species Nr. 267 to 268. 



For tho sul)soquent species of Eriocron we have made \'ierhap- 

 per's well-knoNvn iiKmocrraph (Bcih. BcA. CentralM. XIX Abt. 11 II. 3. 

 1906) and tlic sujtplomontal observations on the northern and arctic 

 ones by Linu.man (Bot. Not iser 1910 p. Hil IT.) tho base of our under- 

 standing and classification. Vierhappkr iias for his work made a cri- 

 tical revision of the spocimens presorved in most of the larger museums 

 of Europe, amongst tiiem the material from Greenland in the H. H. In 

 the following therefore the remarks on the geographical distribution ol" 

 the species in West Greenland chicfly rest upon his work or his determ- 

 inations, whereas we are responsible for the observations on the occur- 

 rence of the species on their natural habitat and on their biology, as 

 well as for some details regarding the distribution of the various species 

 occurring near the limits of their range.

! 267. Erigeron unalaschkensis (D. C.) Vierh. 1. c, Lindman, 1. c, 

 E. iinifloriis Lge. p. p. non L., E. iiniflorus var. pulchellus Fr. Lange et 

 Auctt. Complur de Fl. Groenl., E. arcticus Rouy). 



In sheltered position: on herb-mats, on spots with long lasting snow. 



Disko: Commoii in the whole of the southern part as well as in the fjords, 

 rather common on the west coast, but scarce on the coast towards Waygat, especi- 

 ally on its northern part (P.). — Hare O (P.). 



Mainland: Xugssuaq peninsula common (P.) land east of Disko Bay rather 

 common, becoming scarcer southwards (P.), archipelago of P^gedesminde rather 

 common (P. & E.); in the large fjords in the southern part of our area scarce, often 

 only on the northern slopes or near the summits of the hills (P. & E.). 



A northern type, south of our area observed in the Godthaab 

 fjord at Ujaragssuit (descended from the high-land?) (S. H.) and from 

 Jensens Nunataq, 62°40', at the altitude of 4100' (Korn.), its southern 

 limit. The northern limit is still unknown, but may be somewhere 

 north of 73°. At this parallel the species becomes remarkably scarcer, 

 and from Northern Greenland and I'^llosmereland it was not reported 

 by SiMMONs. 



Abundantly flowering and fructificating. 



Ascending to considerable attitudes. 



Covered by thirk invers of snow during winlor. 



T 268. Erigeron eriocephalus .1. \ ahl. Li.numan 1. c. 



{E. uniflorus var. or subsp. eriocephalus. Vierhapper et Auctt. Compl. 

 sicut Berlin, Rosenvinge, Simmons, Kruuse etc). 



In fresh morainic soil, bare clayey spots in heath, in exposed bar- 

 rens, sometimos in brook-gravel and deltas, descended frnm tho high- 

 land.
