 has been given to almost every Northern form of Leticodrabae 

 that could not be referred to Draba nivalis Liljebl., or Draba

 322 and p. 326), which forms he afterwards combined under 

 the name of Draba rwpestris R, Br. (Botaniska Notiser 1841 

 p. 220), but D. rujyestris was meanwhile reduced only to a 

 subspecies of D. hirta (in Handbok i Skandinaviens Flora 

 ed. 5 1849 p. Ill) by C. J. Hartman. This was also the 

 case witli Draba incano-hirta Hartm. (= D. hirta Lindbl.

 Norges Flora t. 3 (1876) p. 986), of which Hartman him- 

 self had made a species in the 2nd edition of the same work 

 1832 p. 178. It must, howewer, be noted, that both Draba 

 dovrensis, Draba laxa and Draba scandinavica occur as spe-
