Deciduous tree, up to 14m, diameter 70cm. Hermaphrodite. Male inflorescence shorter than the female inflorescence. 1930 Professor Zhong Guanguang 240m above sea level at the Putuo Mountain in Zhejiang Province found that in 1932 Professor Zheng Wanjun identified and named the Putuo Carpinus, except only one specimen tree, but then again not found in other places. National level to protect endangered species. Putuo is a famous Buddhist shrine, visited Putuo temple of the people will not forget that the temple courtyard of a tree, called Putuo Carpinus, The reason it is well known, but because it is the only remaining one was as a national protected plants. Putuo Putuo Temple, together with Carpinus Putuo important for exploring scenic spots. Putuo Carpinus deciduous tree, 13 meters high, diameter 70 cm. Bark relatively light gray. Leaves alternate, ovate elliptic, 5-10 cm long, 3.5-5 cm wide; pinnate veins until the leaf margin serrated top. Flowers unisexual, monoecious. Male inflorescence was born one year old branches, drooping. Consequences of female 2.5-3.5 cm long sequence, drooping. If asymmetric long oval shell, with a small inner lobes. Small nut oval, 5-6 mm long. Putuo temple only plants should be doubly protected from needless to say, another step is to protect the junction of the tree species research and thrive. Hangzhou Botanical Garden has been to try to grow successfully. ~~~~~~~~~~~~~~~~~~~~~

Zhejiang Province (Putuo Island) Status of endangered species. Putuo Carpinus for our endemic species only found in Zhoushan Islands, Putuo Island. As the destruction of vegetation, habitat degradation, at present only one save on the island Fodingshan. Because of the frequent strong winds during flowering and seed invasion, resulting in low seed _set_, seeds will mature, more complex by the typhoon were blown, updated very weak ability, but not the surrounding trees and seedlings, has been at the brink of extinction position.

Protection measures
Putuo Mountain is classified as national key protected areas, natural scenery, and _set_ the Authority, the protection of this species attaches great importance to prevent the visitors pull down, has recently been added in the dam around the plant enclosure. Local authorities and the Hangzhou Botanical Garden has been the introduction and cultivation, and a variety of breeding experiments.

Cultivation
Seed propagation and cuttings. Seed propagation, to adopt appropriate after sowing, the seed due to short life, intolerance storage. In mid-November sowing, excavated the following year in early April, but the seedling rate is not high, delicate seedlings need shade. Year seedlings of high 5--15 cm, the third for points in the spring planting, seedlings average height of 100 cm, the average base diameter of 1.5 cm. Cuttings, seedlings of the use of two lateral cuttings in mid-March, when the average height 8 cm, up to 17 cm.
