Recently, when the scientific and technological personnel of Guizhou Qiandongnan Forestry Science Research Institute were investigating the plant resources in Rongjiang County, they accidentally found a rare plant that is unique to China and is on the verge of extinction, namely the national level I key protected plant, the special-shaped yussaenda anomala Mussaenda anomala is a rare species in the genus of Rubiaceae The lobes of sepals of most species in this genus are usually expanded into petals, while the 5 lobes of sepals of heteromorphic jade leaf are all expanded into white petals with special morphology, which is of great scientific research value The distribution area of heteromorphic yuyejinhua is narrow, only distributed in Lufeng County of Guangdong, Dayaoshan of Guangxi and Congjiang, Rongjiang, Liping, Libo in the southeast of Guizhou Due to the strict requirements of environmental conditions, the distribution area is discontinuous, the area is very small, and the number of individuals is very rare Almost all of them are distributed on the farmland or roadside under the mountain with good light and soil conditions, so they are seriously disturbed by human beings and the plants are frequently cut down In recent decades, through many investigations, the total number of plants in the distribution area of Guizhou is no more than 60.
