Also called orange-peel clematis, Russian virgin’s bower, and tube-flowered clematis, this herbaceous climbing vine is native to  forests, open areas, and riparian area in central to northwestern China.  It is a member of the buttercup family, Ranunculaceae, that also includes delphinium, columbine and hellebore.  Plants grow up to 15′ long and climbs if suitable structures are nearby or sprawls on the ground with the appearance of a shrub.  The  slightly pubescent stems carry pinnate to bipinnate lanceolate leaves with oblong leaflets  that are up to 2.33″ long and have acute tips and finely serrated margins.   From mid- summer into fall  bright yellow bell-shaped flowers appear and open to 3-4″ across before giving way to feathery, whispy seedheads that are ornamental and easily dried for use in arrangements. Plants are attractive growing on shrubs as well as walls, trellis, and arbors.    The genus name, Clematis, is the ancient Greek word klematis meaning a climbing plant.  The specific epithet, tangutica, honors the Tangut people who live in one of the areas where the plant is native.
