--><p><i>Ivesia unguiculata</i> is found in mid-elevation meadows of the central Sierra <i>Nevada</i>, mostly north of the Kings River. The distinctive deep red to purplish coloration of the inflorescence, and the plant in general, can make patches of this species conspicuous as a smoky purplish haze in meadows. The shape and color of the inflorescences are similar to those of the sympatric <i>Horkelia fusca </i>var.<i> parviflora</i>, suggesting shared pollinators.</p><!--
--><p>The description and illustration by J. D. Hooker (1881), supposedly of <i>Potentilla</i> (<i>Ivesia</i>) unguiculata, were based actually on material grown from seed of <i>I. sericoleuca</i> due to initial confusion of the two species (W. H. Brewer et al. 1876–1880, vol. 1).</p><!--
--><p>The type (Kellogg s.n., CAS) of <i>Potentilla</i> ciliata Greene (not Rafinesque) is unquestionably this species; however, the purported locality (Owens Valley, Inyo County) is dubious and most likely an error in the labeling of the specimen by the collector.</p>
