--><p><i>Horkelia truncata</i> is confined to the Peninsular Ranges of San Diego County, California, and northern Baja California, Mexico. Plants of the species are unusual in <i>Horkelia</i> in that the terminal leaflet is usually notably larger than the lateral leaflets, unlobed, and distinct, rather than confluent with the distal lateral ones.</p>
