--><p><i>Alsia</i> is strikingly similar to <i>Forsstroemia trichomitria</i>, but the two taxa are completely distinct geographically. <i>Alsia</i> is endemic to the west coast of North America, while <i>F. trichomitria</i> is broadly distributed in eastern North America, occurring no further west than Oklahoma. The stems of <i>Alsia</i> are densely invested with paraphyllia, while paraphyllia are absent in <i>F. trichomitria</i>.</p>
