Abstract:

In bringing my monograph of western North American Arabis, published in 1941, up to date, a considerable extension of information concerning previously little know taxa has been made. Range extensions or clarification of the taxonomy of Arabis fernaldiana and A. shockleyi is given. A putative hybrid betwen A. holboellii var. pendulocarpa and a new species, A. williamsii, is discussed. New taxa, A. ophria from Nevada, A. lasiocarpa and A. pulchra M E. Jones var. duchesnensis from utah, and A. williamsii, from Wyoming are described.
