Ll 177. Draba subcapitata Sim. 
This very small species of the high north has not been known 
with certainty till after the investigation by Simmons (Ellesmereland, 
p. 87 ff.); it has been found a few times at the north limit of the area. 
Disko: The north-east coast a little north of Kiganguag 70°10’ (P. 
Mainland: From the mouth of the great river of Nigssuaq and southward 
several places 70°20’—25’ (P.); in these places growing on very barren rocks of 
trap-breccie. 
The mentioned places represent the southern limit of the 
species in Greenland. 
Flowers and fruits abundantly. 
No doubt snowless during winter. 
! 178. Draba hirta L. (Incl. Dr. rupestris R. Br.). 
In all sorts of soil from the most barren fell-field and rocks to vi- 
gorous heath, herb-mats, copses and grass-fields of the lowland: often 
in manured soil. 
Very common throughout the whole area. 
Widely ranging in West Greenland. but particularly a northern 
type. The continous distribution stops at about 64° according to Ro- 
SENVINGE; south hereof very rare, no doubt alpine. 
Varies very much, most of the varieties being of ecological nature. 
Very abundantly flowering and fruiting. 
Often snowless during winter. 
V 179. Draba arctica J. Vani (? Dr. magellanica Lam. EKMAN: 
Nomenclature of some North-European Drabae. Ark. f. Bot. 12. 
No. 7 1912 p. 2). 
In places similar to those of the preceding species. 
Disko: Hare © and the Mainland down to the ice-fjord of Jakobshavyn, 
common but not in the same degree as the foregoing. South of the ice-fjord rather 
scarce: at 68°30’ (P. & E.); Kangerdluarssuk at Agto 67°55’ (BE. P.); N. Stromfjord, 
Ungoriarfik (Korn.), not seen by us anywhere in the fjord; From the neighbourhood 
of Holsteinsborg and the adjacent fjords recorded by many collecteors. 
A northern type, having its southern limit of continual di- 
stribution in West Greenland at ca. 67°, but occurs isolated at 64°10’. 
I cannot accept the opinion expressed by Simmons and other au- 
thors, that Dr. arctica is to be considered a variety of Pr. hirta. | will- 
ingly admit the difficulty of referring certain specimens to one of the 
species, but judging by their occurrence in nature | have the decided 
impression that they are different; and the most important mark: the 
pubescence is hereditably constant.
