Commonly distributed in all formations, 2 — 20ctm. 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.
