Tellima grandiflora is found in moist, shaded sites from Alaska and British Columbia to California south of San Francisco. It resembles species of Mitella in its finely pinnatifid petals but is distinguished from most of them by the two to three conspicuous, alternate, cauline leaves in Tellima. It is distinguished from M. caulescens by the latter’s basipetalous anthesis.
