Abstract: Dolichomitriopsis diversiformis is the only Dolichomitriopsis species in China, and is the member of Lembophyllaceae. Ten random primer pairs were selected to amplified 153 individuals from 14 D. diversiformis populations from both northern and southern slops of Fanjing Mountains by using RAPD methods, and 196 sites were derived . Results suggested that (1) D. diversiformis from FanjingMount kept a high level genetic diversity, and the genetic diversity is relative low at the population level ; (2) genetic diversity have no relationship with altitude, but populations on southern slope have a little higher diversity than that on the northern slope; (3) 63.29% genetic diversity exist among populations, and only 36.71% within population. These results suggested that small habitat was the major impact factors of D. diversiformis genetic diversity, genetic drift and habit adaption should be the prominent reason of population differentiation .
