Rare plants, because:
It is a residual plant left over from the Cenozoic Tertiary 654.38 million years ago. During the Quaternary Glacier Period, Davidia involucrata in most areas became extinct one after another, and only some areas in southern China survived, becoming "living fossils" in today's plant world.
It is an ornamental plant because:
1. Davidia involucrata is luxuriant with leaves as big as mulberry and flowers as homing pigeons spreading their wings. White bracts are like the wings of pigeons, crimson flowers are like the heads of pigeons, and green and yellow columns are like the beaks of pigeons. When flowers are in full bloom, they are like pigeons spreading their wings, symbolizing peace.
2. Davidia involucrata is widely distributed in China. There are a large number of Davidia involucrata in Wang Jiazhen, Gongxian County, the hometown of Davidia involucrata. Others are located in Zhenping and Gao Lan in the southeast of Shaanxi, Shennongjia, Xingshan, Badong, Changyang, Lichuan, Enshi, Hefeng and Wufeng in the west of Hubei, Sangzhi, Dayong, Cili, Shimen and Yongshun in the northwest of Hunan, Songtao, Fanjingshan, Daozhen, Suiyang, Bijie and Nayong in the northeast of Guizhou, Wushan in the east of Sichuan and Nanyong in the southeast. It is often mixed in broad-leaved forests at an altitude of 1250-2200m, and occasionally there is a small piece of pure forest. In recent years, a large number of Davidia involucrata forests have also been discovered in Yingjing County, Sichuan Province, reaching 65.438+10,000 mu. Thousands of acres of pure Davidia involucrata forest were found at Tianping Mountain in Sangzhi County, 700 meters above sea level, which is the most concentrated place of Davidia involucrata found at present. Since 1869 Davidia involucrata was discovered in Mu Ping, Sichuan Province, Davidia involucrata has been introduced to various countries and become a precious ornamental tree species, which is deeply loved by people all over the world. Davidia involucrata was first discovered by the French missionary David as a westerner, and he also named the Latin species for the elk. Davidia involucrata was introduced to Europe and North America in 1904 and became a famous ornamental tree species.
Lotus is cultivated in the form of pond, which is an economic crop. (But the lotus here does not refer to the water lily, but the lotus, which is another name for the lotus. )
