Abstract
The cytotaxonomy of the following group of leafy-stemmed, white-flowered species of Draba is discussed and a key is presented: D. glabella Pursh (2n = 64 and 80), D. arabisans Michx. (2n = 96), D. borealis DC. (2n = 80), D. longipes Raup (2n = 64), D. incana L. (2n = 32), and D. norvegica Gunn. (2n = 48). Scanning electron microscopic examinations were made on the morphology of pollen grains and basal leaf hairs.Keywords
