--><p><i>Chaenactis santolinoides</i> is known from the southern Sierra <i>Nevada</i> and Transverse Ranges. It is sometimes cultivated in rock gardens and may be found beyond its native range. It may be relatively recently derived from an isolated segment of <i>C. douglasii </i>var.<i> alpina</i>. The morphology of <i>C. panamintensis</i> (here assigned to <i>C. douglasii </i>var.<i> alpina</i>) suggests past convergence toward, or genetic influence from, <i>C. santolinoides</i>.</p>
