appear in the axils of the old rosettes, the plant in this way being pe- 
rennial. 
This is the case with the plant from Greenland (Julianehaab, Qa- 
qortoq leg. С. Petersen; Arsuk leg. Lindhard; Qegertalik at Holstein- 
borg leg. Porsild), but I have also seen it on specimens from the Alps 
with inflorescences from the preceding year (Scarl., leg. BRAuN-BLAN- 
QUET) and from Scandinavia (Visby, leg. К. Jonansson). 
Other specimens from Greenland and elsewhere do not flower till 
alter a strenghtening of several years. Specimens flowering in the se- 
cond year I have seen from the southmost part of Greenland (Pamiag- 
dluk, leg. E. Lundholm) and this was also the case with plants culti- 
vated here on Disko from seeds brought from Rigi-Scheidegg in the 
Alps. (СЁ. also ELISABETH EKMAN, Arkiv f. Bot. 12. No. 7, р. 15). 
To be sure covered by snow during the winter. 
A 172. Draba aurea M. VAHL. 
On spots favourably exposed to the sun, sandy and gravelly slopes. 
Disko: Very rare; Diskofjord: Ikineq 69°25’ (P.) and Kuanerssuit 69°35’ (Р.). 
Mainland: Rare at Disko-Bay: Sarqaq about 70° (V.); Jakobshavn (V.); 
in surroundings of Sydost-Bugten several places, Sofiehavn (BL); Simiutarssuaq 
in the district of Egedesminde (K.); N. Stromfjord, several places (P. & E.), for 
instance, at the tenting-place Ugssuit it was characteristic of clayey-gravelly slopes. 
Becoming more frequent southwards; common in the fjords inland from Holsteins- 
borg (Р. & E.). 
A southern type, the mentioned places represent the north-limit 
Abundantly flovering. the seeds are often only partially developed. 
Hibernates covered by snow. 
V 173. Draba alpina L. 
On new moraine, in open spots on heath and generally to be found 
in waste tracts. 
Disko: The northland especially along Waygat, rather common (P.); in the 
southland rare, most frequently washed or blown down from the hills. 
Diskofjord: Kuanerssuit 69°35’ (P.); Maligiaq (Sor.); from several places near 
Godhavn (P.). | 
Hare Ø (Nath.; P.). 
Mainland. Rather common from the coast and interior of Nugssuaq penin- 
sula (P.); from several places near Torssukåtak. South of the ice-fjord of Jakobs- 
havn very rare: Lerbugten about 69° (Bg.); Akunåq about 68°40’ (Sor.); Simiu- 
tarssuaq about 68910” (K.). 
A northern type, the above mentioned places represent the 
south limit of its continual distribution. Quite isolated it has been found 
on Jensen's Nunataq 62°50’ at an altitude of 1250 m.
