Commonly distributed in all formations, 2—20 ctm. high, flowers 
from the 20** of June till October, sets abundant ripe fruit. Varies 
very much. Most common are forms belonging to D. rupestris R. 
Br., but also specimens belonging to the main form are common 
in sheltered localities; when growing in much exposed habitat, it 
is reduced to a minimal size (f. stricta, f. trichella), but it becomes 
very robust on manured ground with broad dentate leaves and a 
thick, stem. The hairiness varies very much from the thick hairy 
small forms to almost glabrous. The form and hairiness of the 
silique is likewise subject to great variations. After having examined 
the great material at my disposal, I do not, however, consider it 
possible to keep the individual forms from each other, and there- 
fore I do not note them down. The species is, like the genus of 
Draba on the whole, certainly strongly developping, and possibly 
forming new species; but these cannot be determined till after 
having been cultivated through years in favourable localities within 
the arctic circle. I consider the different forms only climatic and 
local varieties of one or few fundamental forms.
