Although Draba santaquinensis was included within D. brachystylis by previous authors, I. A. Al-Shehbaz and M. D. Windham (2007) have shown that it is distinct both morphologically and chromosomally. It is currently known only from Utah County (American Fork, Provo, and Santaquin canyons) in north-central Utah. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
