--><p><i>Filipendula occidentalis</i> is known only from the valleys of several small rivers in the coast ranges of northwestern Oregon and southwestern Washington. The species is threatened by logging and associated forest-management activities. The species is most probably related to F. camtschatica (Pallas) Maximowicz from the Pacific coast of Asia.</p>
