Abstract: By using DCA ordination and TWINSPAN classification,a total of 69 plots with endangered plantBerchemiella wilsonii var.pubipetiolata were partitioned into 9 community types.Both the methods of DCA ordination and TWINSPAN classification obtained very consistent results.B.wilsonii var. pubipetiolata had a high habitat speciality,and grew well in four communities,i.e., Liquidambar formosana community,Pinus massoniana+Cunninghamia lanceolata+Quercus glauca confer and broadleaf mixed community,complex community,and Acer davidii+Lindera praecox community.The understory of the four communities had some evident similarities,i.e.,Oplismenus undulatifolius and Aster ageratoides were the two dominant species of herb layer,and L.praecox was one of the dominant species of shrub layerB.wilsonii var.pubipetiolatamostly distributed in low altitude (500-900 m above sea level) mountainous region characterized by higher humidity and well drainage,and was mostly found at northern slopes.
