|discussion=<p><i>Streptanthus bernardinus</i> is known from San Bernardino and San Diego counties; in Baja California it is restricted to Sierra Juárez and Sierra San Pedro Mártir.</p><!--
--><p>The chromosome number 2n = 14, reported by R. C. Rollins (1993) and by R. E. Buck et al. (1993), must be an error for n = 14. No other species of <i>Streptanthus</i> or its immediate generic relatives has such a low number.</p>
