Abstract: The seed of mosla hangchowensis is carried by wind, but the distance is not long because the seed is big. The seed is dormant during the winter and germinated in spring (late Feburary or early March). The ratio of germination, specially the upper layer seed chosen by water was very low because of its low quality. The vegetative stage of M. hangchowensis was from March to August. The height increased in a even speed before the middle of August, and the growth in the early stage was very slow. The morphology and seminal power were affected greatly by environment. The crown range of the plant in natural habitat varied between 4～5616cm2. Sometimes M. hangchowensis composed the consociation in nature habitat, and commonly grown with other species. The competitive ability of M. hangchowensis in community was limited by the slowly growth in the early stage ,so it was pushed out of better soil environment ,and lived only in the habitats where there were high temperature ,aridity and little soil due to its strong bearing ability to drought.As a comparison,the seed of Mosla chinensis wich belonged to the same genus as M. hangchowensis but not endanged was smaller but the ratio of germination was higher. The flower of M. chinensis was smaller than that of M. hangchowensis, and the colour of the plant and flower was not as bright as M. hangchowensis, so it was not easily to be plucked by people like M. hangchowensis, if both of them lived beside the road. The root of M. chinensis was deeper than that of M. hangchowensis, and was not easy to be washed out by rain like M. hangchowensis. The reproduction allometry of Mosla chinensis was bigger than that of M. hangchowensis.
