|discussion=<p><i>Pilea fontana</i> and <i>P. pumila</i> are separated primarily by differences in their mature achenes. In addition, leaves of <i>P. fontana</i> are often more opaque and less shiny than those of <i>P. pumila</i>. A few collections of <i>P. pumila</i> from Bourbon, Owen, and Robertson counties, Kentucky, and Macon County, Tennessee, have the black achenes of <i>P. fontana</i>, but without the bosses, and show striations on the younger achenes as in <i>P. pumila</i>. I have seen only two mixed collections (Chisago County, Minnesota, and Richland-Ransom county line, South Dakota), which probably indicates that these two very similar species seldom occur together, even though their ranges overlap completely.</p>
