The genetic variation in the critically endangered species Isoetes hypsophila was investigated using Random Amplified Polymorphism DNA (RAPD) markers. Thirteen primers were screened from sixty primers, and a total of 104DNA fragments were scored, of which, 52 were polymorphic loci. Low-level genetic diversity within populations with PPB values ranging from 7.69% to 25.96% was found. An Anal ysis of Molecular Variance (AMOVA) indicated that the most of variance (78. 30%) occurred between Yunnan and Sichuan. The variances among populations within regions and within populations were only 3. 89% and 17. 82%, respectively.
