are narrowly ovate or oblong with the exposed part striate and glabrous with a thickened margin. Regardless of its taxonomic status, it is considered threatened by the IUCN. It occurs only in northeast Guizhou, southwest Sichuan and northwest Yunnan. T. c. var. robusta is probably the most universally recognised of the varieties. It is present in western Hubei and western Sichuan. It again exhibits the thicker branchlets and larger cones, but the cones are stout and shortly cylindric. Also, the seed scales are square-orbicular with the exposed part being pubescent and the margin not thickened. In addition, the bracts are cuspidate at the apex. T. c. var. oblongisquamata is considered a separate species by Raven and Wu, namely T. oblongisquamata, but as a variety by Farjon. It occurs in the northern part of the range, namely in southern Gansu, western Hubei and northwest Sichuan. It differs most sharply in lacking visible stomatic bands beneath the leaves. Otherwise the seed scales are more loosely arranged and loosely elliptic in shape, being nearly twice as long as they are wide. Uses The timber obtained from T. chinensis is used in construction, furniture making, and as a support in mines. The bark is high in tannins, which is often extracted and used as a dye. The trunk is used as a source of resin. In addition, the roots, trunk, and branches are all used in the production of aromatic oils due to their pleasing scent.
