--><p><i>Potentilla uliginosa</i> is known only from a handful of historical collections from Cunningham Marsh, one of three wetlands in southern Sonoma County that harbor a suite of disjunct and regionally rare species (B. C. Johnston and B. Ertter 2010). Although previously included in <i>P. hickmanii</i>, <i>P. uliginosa</i> differs in having woodier caudices, longer stems and leaves, and more deeply incised leaflets occupying less of the leaf axis. <i>Potentilla uliginosa</i> is presumed extinct; however, a morphologically comparable collection of the <i>P. millefolia</i> complex from Josephine County, Oregon (Deer Creek, near Selma, 14 June 1929, Applegate 5735, UC), opens the possibility of additional undiscovered populations in the mountains of northwestern California.</p>
