Abstract There are 1 125 species (including varieties and forms)of 529 genera in 167 families. Among 167 families,81 families belong to tropic areal-types,accounting for 63. 78% in totaKexcluding cosmopolitans) ;46 families show a temperate areal-type, with 36. 22% of the total. At the level of families, the tropic aeral-type holds a dominant position. The genera can be divided into 14 areal-types and forms,in which the Tropic one accounts for 47. 80% in total with 228 genera. The pantropic which is the dominant floristic element in this medicinal seed flora has 108 genera accounting for 22. 85% in total and 53. 51% in Tropic ones respectively. Temperate areal-type and forms have 238 genera,accounting for 49. 89% in total. The China-endemic accounts 2. 31% with 11 genera. All kinds of floristic elements coexist in the Nature Reserve. There are both far ancient elements and new or special ones. It has wide and complex relationship with the other regions in the world. The flora of Jinggangshan is a transitional zone from subtropic to temperate.
