[Phylogenetic analyses of some important Paris species based on sequences of matK gene].
The matK genes of 10 samples in Paris from Hunan, Yunnan and Jilin provinces were sequenced and compared. The phylogenetic tree was constructed based on the matK gene sequences and the ten pairs samples were divided into four groups. The results did not support the reality of four taxa named P. polyphylla var. pseudothibetica, P. polyphylla var. yunnanensis, P. polyphylla var. appendiculata and P. polyphylla var. chinenis. They are supposed to be treated as different forms of P. polyphylla var. polyphylla.
