Abstract: The random amplified polymorphic DNA(RAPD)was used to analyse the phylogenetic relationship among fifteen mosses species from Northeast China in which Hylocomium Splendens, Pleurozium schreberi, Rhytidium rugosum, Rhytidiadelphus squarosus, Neckera pennata, Thamnobryum alopecurum and Climacium dendroides distribute extensively in northern semiglobe, and Okamuraea brachydictyon, Gollania varians and Polytrichum sphaerothcium are representative species endemic to East Asia.The results showed that the RAPD results support the classification of these mosses based on morphology.All the 15mosses species were clustered in Polytrichinales, Isobryales and Hypnobryales.Okamuraea and Gollania have a closer phylogenetic relationship with Hyitidiaceae.Pleurozium has a closer phylogenetic relationship with Entodon, so it is suitable for Pleurozium to be placed in Hylocomiaceae.
