[Wikipedia] Taxonomy: Tiarella trifoliata was first described by the Swedish botanist Carl Linnaeus in 1753.[2] Its type specimen was collected by Georg Steller on Cape St. Elias, Kayak Island, Alaska in 1742, but that specimen is now lost. A specimen collected from Sitka, Alaska has been designated as the neotype for this species. (contributed by Mary Ann Machi)
