| Abstract: | According to statistics,20 species of Stellaria L.have been discovered in North China.The patterns of their vertical and horizontal geographical distribution are studied.The results show that the richness center of the species lies in Shaanxi,Hebei,Beijing,Shanxi and so on and they vertically distribute below an altitude of 3800 m.The distribution and diffusion of each species is discussed as well,with the floristic characters summarized.The results verify that North China is the transitional region of Stellaria L.distribution in the country. |
