Abstract:

The present paper deals with the genus Paeania in Xinjiang, whose taxonomy has been confused. Based on the field observation, population sampling and the examination of herbarium specimens, a taxonomical revision is made in this paper. Two species are recognized , i. e. Paeania. anamala L. and P. sinjiangensis K. Y. Pan. P. altaica K. M. Dai et T. H. Ying is reduced to P. sinjiangensis and P. hybrida (= P. anamala var. intermedia) is reduced to P. anamala. The diagnostic characters of the two species are described and illustrated, and a map of their distribution in Xinjiang is presented. A key to these two species is provided here. 1. Roots straight, not thickened; sepals all caudate, less frequently one or very rarely two non-caudate ................................................ 1. P. sinjiangensis K. Y. Pan. 2. Roots fusiform or tuberous; inner three sepals non-caudate, less frequently one of them caudate ........................................................................ 2. P. anomala L.
