--><p><i>Ivesia webberi</i> is known only from the eastern foothills of the northern Sierra <i>Nevada</i> and scattered ranges to the east in California and adjacent <i>Nevada</i>. It is among the more distinctive species in the genus and is only tentatively placed in sect. <i>Ivesia</i>. The leaflets are loosely incised into slender, sparsely villous segments, and the two cauline leaves are paired with dissected stipules. Previous reports of the stems and inflorescence branches being glandular-puberulent are due to a misinterpretation of the minute pustulose bases associated with the villous indumentum as being enlarged glands.</p>
