|discussion=<p><i>Ivesia saxosa</i> is encountered in the foothills and mountains of southeastern California from the White Mountains and adjacent eastern slopes of the Sierra <i>Nevada</i> of Mono County to the Transverse Ranges (including the Little San Bernardino Mountains) of Kern and San Bernardino counties. Populations on the Kern Plateau tend to have more dissected leaflets and may deserve recognition as a distinct variety. On the Peninsular Ranges, <i>I. saxosa</i> occurs in Riverside and San Diego counties and into northern Baja California, Mexico, as far south as the western slopes of the Sierra Juárez and Sierra San Pedro Mártir.</p>
