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. C. Petersen; Arsuk leg. Lindhard; Qeqertalik 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 Seandinavia (Visby, leg. K. Jonansson). 
Other specimens from Greenland and elsewhere do not flower till 
after a strenghtening of several years. Specimens flowering in the se- 
cond year I have seen from the southmost part of Greenland (Parmiag- 
dluk, leg. E. Lundholm) and this was also the case with plants eulti- 
vated here on Disko from seeds brought from Rigi-Scheidegg in the 
Alps. (Cfr. also ErisaretH Exman, Arkiv f. Bot. 12. No. 7, p. 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’ (P.). 
Mainland: Rare at Disko-Bay: Sarqaq about 70° (V.); Jakobshavn (V.): 
in surroundings of Sydost-Bugten several places, Sofiehavn (BI.); Simiutarssuag 
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 (P. & E.). 
A southern type, the mentioned places represent the north-limit 
Abundantly flovering. the seeds are often only partially developed. 
Hibernates covered by snow. 
Vv 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 © (Nath.; P.). 
Mainland. Rather common from the coast and interior of Nugssuaq penin- 
sula (P.); from several places near Torssukatak. South of the ice-fjord of Jakobs- 
havn very rare: Lerbugten about 69° (Bg.); Aktanaq about 68°40’ (Sor.): Simiu- 
tarssuaq about 68°10’ (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.
