Polyploid plants could be useful in generating novel and improved breeding populations. We report 47 meiotic chromosome number determinations for 19 species of <em>Physaria.</em> The first chromosome number is reported for <em>P. kingii </em>subsp. <em>kaibabensis </em>as 2<em>n</em> = 5 II, and the first report of polyploidy in <em>Physaria kingii </em>susbsp. <em>latifolia</em> with a tetraploid determination of 2<em>n</em> = 10 II. A determination of 2<em>n</em> = 23 II is reported for <em>Physaria mendocina</em>, which was previously reported as 2<em>n</em> = ca. 50, which results in a new base number for the genus of x = 23.</p>}, number={2}, journal={Journal of the Botanical Research Institute of Texas}, author={Salywon, Andrew M. and Rebman, Jon P. and Dierig, David A.}, year={2022}, month={Nov.}, pages={499–504} }
