Exetroderon Hsiemvu (Chunehow) H.T. Changetmiu, also known as firewood, is an evergreen tree of Tiliaceae, which is an endangered species. It is distributed in monsoon forest, a tropical limestone mountain with an altitude of 700 to 900 meters in Guangxi and Yunnan. The distribution center of this species is in the south of Guangxi, extending to the limestone area in the southeast of Yunnan to the west, and crossing the Tropic of Cancer to the north, it gradually becomes an occasional species and disappears. In Yuanjiang, it is the northern edge of this species distribution, which is relatively rare. Young trees are shade-tolerant, and 10 years old and above need full sunlight. It blooms in March, and the fruit matures in June, with an interval of 2-3 years. It is one of the constructive species of the primitive limestone seasonal rain forest in the north tropics, and it is a unique plant of tropical limestone, which has important research value. Its wood is heavy and has good mechanical properties. It is a precious material for machinery, special buildings, shipbuilding and high-grade furniture, and also a good material for chopping boards.
