Based on cpDNA and other cytological traits, this is one of the best-defined groups of the Saxifragaceae. Chloroplast DNA restriction site data for the <i>Heuchera</i> group suggest the group as being paraphyletic. <i>Tiarella cordifolia</i> is known from eastern North America and <i>T. trifoliata</i> is known from western North America. <i>Tiarella</i> polyphylla D. Don occurs in Asia in the Himalayas through western and central China to Japan and Taiwan. <i>Tiarella</i> is used as a diuretic as well as for suppression of urine production and in treating kidney stones.</p> |tables= |references={{Treatment/Reference |id=lakela1937a |text=Lakela, O. 1937.
