Except T. sutchuenensis, Franch., from western China, the species are in cultivation and their numerous garden forms are much planted for ornament. A. Branchlets in horizontal planes: cone-scales thin; seeds thin, winged. (Subgenus Euthuja.) B. Leaves of primary axes widely spaced, ending in a long point parallel to the axis, c. Primary axis flattened: leaves conspicuously glandular, yellowish- or bluish-green below 1. T. occidentalis cc. Primary axis nearly terete: leaves not or inconspicuously glandular, usually with whitish markings beneath 2. T. plicata BB. Leaves of primary axes close, ending in a short, rigid, spreading point: young branchlets with more or less conspicuous white markings below. c. Under side of leaves slightly or not concave, glandless: branchlets thickish, compressed, but scarcely flattened. .3. T. Standishii cc.
