A medium sized evergreen tree, ranging from 25 to 40m in height with a trunk diameter up to 1.5m. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by wind. They are endemic to Sichuan province and are rare in number, they are a Class II state-protected species.It forms mostly pure forests with other species of Picea, in the south of Gansu it may be mixed with Abies nephrolepis. Betula albo-sinensis is the most common broad-leaved associate. Sargent Spruce - Picea Brachytyla
An evergreen arbor as tall as 41m with a 1 m trunk diameter, tower shape, extended branches, Picea Brachytyla grows from about 2,000m and is one of the main sub-alpine coniferous species. Endemic to China, Picea brachytyla is a Class III state protected species.Leaves directed forward and closely appressed on upper side of branchlets, spreading and almost pectinate on lower side, linear, slightly curved or straight, flattened, 10-25×1-1.5 mm, slightly keeled on both sides, stomatal lines 5-7 in each of 2 white Yew - Taxus chinensis or sumatrana It grows from about 1,600m in evergreen broad-leaved woods and broad-leaved and coniferous mixed woods. Endemic to China and with an oil content of over 60%,The Chinese yew has fleshy seeds that ripen into a red colour, and a grey-red bark which exfoliates in irregular 1.5 mm thick flakes and leaves scars on the trunk that appear yellow quickly after cutting. it is good for soap and refined lubricant production, it is also edible and used for anti-ascariasis. Because of its beautiful shape, it is an ornamental plant good for gardening.
Katsura Tree - Cercidiphyllum japonicum
A deciduous tree, as tall as 40m, 3m trunk diameter. Grows on hillsides and valleys up to 1,800-2,000m. Cercidiphyllum japonicum is a Class- Ⅱ state-protected plant, the only species in the katsura family, and a surviving species from ancient times. It is a key species when studying plant zonation. In autumn, the leaves turn golden yellow. The katsura tree grows and regenerates fast, making it an excellent species for reforestation in mountainous regions. Three-pointed Fir - Cephalotaxus fortunei
A tree as tall as 20m and 40m in the trunk diameter, usually grows in coniferous forests that grow up to 1,000 meters.It is a coniferous evergreen that typically grows as a small tree or large shrub to 10' (less frequently to 15') tall. Each needle has two silver-white bands beneath. Reddish brown bark on mature branches exfoliates with age. Their twigs and seeds that are used for medicinal purposes. Spur-leaf Ling Chun - Tetracentron sinense A deciduous shrub or low arbor, growing to 2-l5 m tall. Usually growing on the banks of streams or at altitudes of 1,800-2,400 meters. A Class- III state-protected plant, it has only two species in the family, and is the sole surviving species of the genus Tetracentron. It is of scientific value in the study of the family Trochodendraceae, its evolution and the continuing debate as to which order Trochodendracea fits within.It area of expansion is south-central China, Nepal, and northern Myanmar (Burma),where is a high-sized tree, 4.5 to 27 metres (about 15 to 88.5 feet) tall, with palmately (fingerlike) veined leaves. Unlike Trochodendron, Tetracentron has small, wind-pollinated flowers arranged in dangling, slender catkins; their flowers are bisexual In early spring, it bursts into beautiful blossoms making it an ornamental plant.
Single leafed grass - Kingdonia uniflora A perennial herb, without hair. 3-10 cm tall, usually grows below fir woods and azalea groves at an altitude of 2,500-3,500 meters, mixing with musci (true mosses) species. Endemic to China, it is a Class II state-protected species, the only one of the family, and an ancient surviving species. It can be used as an herbal medicine for muscle and bone aches. Its nutritious leaves branch out like a fork (two branches), similar to that of gymnosperms like gingko and other algae. The ground stalk has one leaf trace, different from that of other Ranunculus species. Studies of this plant will lead to discoveries in the evolution of angiosperms.
Chinese Sinofranchetia or Fruit Chain Rattan - Sinofranchetia chinensis A hairless deciduous tree, up to 10 meters tall grows in evergreen broad-leaved and deciduous forests at an altitude of 1,600-2,400 meters, and tends to climb and circle around tall arbors. Endemic to China, it has only one species, and is an ancient surviving species often studied due to the unique evolution of the Lardizabalaceae family. It can be used in brewing liquor.
