Abstract: Amplified Fragment Length Polymorphism (AFLP) was used to analyze the differentiation of 2 natural species （Paris polyphylla Smith var. minora S.F.Wang & P. thibetica Franch）of Paris of EMEI Mountain. AFLP analysis indicated that there were relatively high genetic comparability among the two species and high genetic differentiation of the P. thibetica Franch and P. polyphylla var. minora with in a geographical region. The flower of morphological diversity was detected among the two species of Paris in EMEI Mountain by morphological analysis.The results suggested that high genetic differentiation and morphological differentiation of the P. thibetica and P. polyphylla Smith var. minora in a geographical region.

Key words: Emei Mountain, Paris, sympatric speciation, P. thibetica Franch, P. polyphylla Smith var. minora, AFLP, genetic differentiation, morphological differentiation
