Abstract: There are 240 species of 46 genera of Labiatae in Hergduan Mts.,Its species amount is less than that of Yunnan and Sichuan, but muchmore than that of Xizang and other provinces in China. After analysingthe distribution of genera and species of Labiatae in Hengduan Mts., weknow the characteristics of the geographical distribution of Labiatae inthis region as follow:i. The distribution-type of genera is mainly oftemperate nature, having a percentage of 85.3% of total genera. (Thecosmopolitan genera are excluded from the total and from the calculationof the other statics.) Among temperate distributron-type, that of Eastern Asia (mainly of Sino-Himalava subtype) has a percentage 34.1% of totalgeneral and that of Old World temerate and North temperate has a percen-tyge of 29.2% and 12.2% of total genera respectively. ii.The distribution-tupe of species is mainly of endemic in China, having a perceutage of 75%of total species. But that of temperate and tropical only have a percentageof 20% and 5% of total species respectively. Among endemic spceis in Chinaabout a percentage of 72.8% is of endemic in Hengduan Mts. The areaof NW Yunnan and SW Sichuan is a most important center of endemieSpecies is Hengduan Mts. It posscss a percentage of 67.2% of total ende-mic species in Hengduan Mts. iii. The origin cause of endemic species imthe area of NW Yunnan and SW Sichuan is mainly of ecological reasonrather than historical reason.
