Abstract: Observations on the chromosome number of four plants in Tibetan are made in this paper.The research results are as follow: Saussurea thoroldii Hemsl.2n = 2x = 30; Saussurea subulata C.B.Clarke 2n = 2x = 30; Arabidopsis stricta (Camb.) N.Busch 2n = 2x = 14; Ephedra monosperma Gmel.exC.A.Mey.2n= 2x= 14,The chromosome numbers of four plants are firstly reported at home and abroad.The vouchers of these plants are deposited in the Herbarium of the institute of biology of Tibetan Plateau in Lasa.
