148 Morven P. Ponrsiip. 
Erigeron species Nr. 267 to 268. 
For the subsequent species of Krigeron we have made VierHap- 
peR’s well-known monograph (Beih. Bot. Centralbl. XIX Abt. I] H. 3. 
1906) and the supplemental observations on the northern and arctic 
ones by LinpmMan (Bot. Notiser 1910 p. 161 ff.) the base of our under- 
standing and classification. VirrHAppeR has for his work made a eri- 
tical revision of the specimens preserved in most of the larger museums 
of Europe, amongst them the material from Greenland in the H. H. In 
the following therefore the remarks on the geographical distribution of 
the species in West Greenland chiefly rest upon his work or his determ- 
inations, whereas we are responsible for the observations on the oceur- 
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. 
i 267. Erigeron unalaschkensis (D.C.) Vieru. |. c., LinpMAn, l. c., 
E. uniflorus Lge. p. p. non L., EL. uniflorus var. pulchellus Fr. LANGE et 
Auctt. Complur de FI. Groenl., E. arcticus Rouy). 
In sheltered position: on herb-mats, on spots with long lasting snow. 
Disko: Common 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 © (P.). 
Mainland: Nuagssuaq peninsula common (P.) land east of Disko Bay rather 
common, becoming scarcer southwards (P.), archipelago of Egedesminde 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 Ellesmereland it was not reported 
by SrmMmons. 
Abundantly flowering and fructificating. 
Ascending to considerable attitudes. 
Covered by thick layers of snow during winter. 
T 268. Erigeron eriocephalus J. Vauu. LinpMan Il. c. 
(EZ. wniflorus var. or subsp. eriocephalus. VrERHAPPER et Auctt. Compl. 
sicut Bertin, ROSENVINGE, SIMMONS, KRuUUSE etc.). 
In fresh morainic soil, bare clayey spots in heath, in exposed bar- 
rens, sometimes in brook-gravel and deltas, descended from the high- 
land.
