　　Hemlock wood square

　　Architectural hemlock, up to 50 meters high, with a chest height diameter of 1.6 meters; The bark is dark gray, longitudinally cracked, blocky; The small branches are flat and slightly drooping, and the crown of the tree is shaped like a pagoda; Winter buds are ovoid or round in shape, with blunt tips and flat rounded or basal scales on the back of the buds; One year old branches are slender, light yellow, light brown yellow or light gray yellow, with short hairs in the occipital sulcus. Two to three year old branches are gray, light brown or gray. The leaves are arranged in a strip like pattern, measuring 1.2-2.7 centimeters in length and 2-3 millimeters in width. The top of the leaves is dull with indentations, with a light green color at the top and a light green color at the bottom. The midrib is raised without indentations, and the stomata are gray green in color. The edges are entire (the upper edges of young leaves often have fine serrations). There is white powder at the bottom of the leaves, and white powder at the bottom of the leaves. There is a layer of subcutaneous cells at the top and edges of the cross-section, and a layer of subcutaneous cells at the bottom and middle.

　　The fruit is elliptical or elongated, measuring 1.5-2.5 centimeters in length and 1.2-1.6 centimeters in diameter, with a short stem; The middle part of the scales is pentagonal elliptical, nearly square or nearly circular, sparse short rectangular circular, measuring 0.9-1.2 cm in length and 0.8-1.1 cm in width. The upper part is circular or nearly truncated, with thin and slightly inward curved edges. The base is bipyramidate, and the exposed part of the scales and the edges are hairless and shiny; The bracts are inverted triangular wedge-shaped or diamond shaped, with fine missing teeth on the upper edge and a semi lobed tip; There are oil stains on the lower surface of the seeds, along with 7-9 mm long seed wings, which are narrower in the upper part. The cotyledons are 3-4 long, elongated, about 1 cm in length and 1-1.8 mm in width, with blunt tips and full edges. The upper midrib is raised and scattered with white stomatal spots. The primary leaves are elongated, 0.7-1.5 cm in length and 1-1.5 mm in width, with blunt or flat tips and no stomatal lines. The lower midrib is raised and has two white stomatal bands along the leaf edge.

　　Wood has a straight texture, a fine and uniform structure, and a solid material that is resistant to water and moisture. It can be used as raw materials for industrial production of Chinese architecture, aircraft, boats, furniture, appliances, and wood fibers. The trunk can be cut for resin, and the bark contains tannins, which can be used for baking glue; Seeds can be used to extract oil.

　　Most of them are used on building roof panels, and wood hardness is their advantage.
