 and- stolonlike, and the 



covering is peculiar, 

 only consisting of nearly

 hairs especially on the 

 margins (Fig. 9). 



Draba affinis Ledeb.

 found in Novaya Zem-

Draba crassifolia Grah. 



Belongs to the Section „Drabeæ" and not to the Section 

 „ Drabella u as quoted by Watson. Both Watson and Lange 

 describe the plant as annual or biennial, but this is not 

 the case, the specimens I have seen from America and 

 Greenland all show that the plant is perennial. Also the

 F. R. Kjellman & N. Lundström).
