Among them, 15 species belong to 14 genera of 8 Families were presented. In this study, 7 species of 4 Families were under group of monocots, 6 species belonging 3 Families were under rosids and the other 2 species belonging 1 Family were under asterids. In these species, 4 species were trees, 5 species were herbs and 3 species were shrubs and other species were climber and epiphytic. The leaf types of 2 species were compound and 13 species were simple. Smilax perfoliata Lour., Begonia lipingensis Irmsch. and Begonia palmata D. Don. possessed unisexual flower and the others were bisexual flower. An artificial key to the studied species was also constructed. The economically valuable timber species are Grewia laevigata Vahl., Kydia calycina Roxb. The most valuable medicinal species are Curcuma petiolata Roxb., Kaempferia galanga L. These valuable species are needed to be conserved as the long-term programme for natural vegetation of Mansi Township, Banmaw District, Kachin State.
