Abstract
Abstract. Four new arctic species of Draba are described here. Of these, D. airdii, D. shehbazii, and D. darbyshireii are from Canada, and D. catlingii is from both Canada and Alaska. Two new species described by others, D. adamsii and D. macrocarpa, are also added. The chromosome numbers n = 19 and 2n = 36 should be attributed to D. grandis, and n = 8 for D. lonchocarpa var. kamtschatica to D. chamissonis. Draba kluanei is now known to occur at a second location in Yukon. The six new Draba species added in this study bring the total number in Canada and Alaska to 65. A key to all of these species is presented.
