Abstract: In this paper the classification of the genus  Bergenia Moench is  provided, its geographic distribution analysed, and the phylogeny also traced. Based  on an analysis of morphological characters such as leaves, ocreas, branches of inflorescences, Pedicels, hypan- thium, sepals, and glandular indumentum, thi genus is divided into 3 sections: 1. Sect. Scopu- losae J. T. Pan, sect. nov., 2. Sect. Bergnia, 3. Sect. Ciliatae (A. Boriss.) J. T. Pan, stat. nov. The Sect. Scopulosae J. T. Pan may be considered as the primitive one, while Sect. Ciliatae (A. Boriss.) J. T. Pan may be regarded as the advanced one, with Sect. Bergenia in between.     So far, the genus Bergenia Moench comprises 9 species in the total.  Southeast Asia and North Asia (south and east Siberia, USSR) each have only 1 species, West Asia (Afghanis- tan) has 2, Central Asia (Kirghizia-Tajikistan-Uzbekstan area, USSR) 3, South Asia 4 (Nepal has 4, India, Pakistan and Kashmir area each has 3, Bhutan and Sikkim each has 2), East Asia 6.  In East Asia, Mongolia and Korea each have only 1 species, but China has 6 (includ- ing endemic species 2 and new species 1).  Sichuan Province and Xizang Autonomous Region each have 3, Yunnan Province 2, Shaanxi Province (Qinling Mountains) and Uygur Autono- mous Region of Xinjiang each have only 1. Thus the distribution centre of this genus  should be in the region covering Si- chuan, Yunnan and Xizang. Moreover, it is noteworthy  that Bergenia scopulosa T. P. Wang in Sect. Scopulosae seems to have retained primitive characters,  for exa- mple, non-ciliate leaves and ocreas, glabrous pedicels, hypanthium and  sepals,  and this primitive species is found in Qinling Mountains and Sichuan.  According to the distribution of the primitive species, the author suggests that the centre of origin of  this genus be in the region covering Qinling Mountains and Sichuan.Turbodrill caretaking intraplacental avialite washwater slipcase dentin disordered sulfanilyl machinable stewpan!
