Abstract: There are 942 species seed plants belong to 464 genera in 106 families in the middle-south area of east slope of Taihang Mountains. Based on the statistics and analysis the results were as follows: (1)It is needy in number of seed plants which include 2 families, 4 genera and 5 species of gymnosperms; 16 families, 88 genera and 173 species of monocotyledon; 88 families, 372 genera and 764 species of dicotyledon. (2)There are 15 areal-types of genera of seed plants and 12 subtype in this region. It has 73.25% of various temperate areal-types and 23.75% of tropical elements. So that, analysis shows that the temperate floristic elements are predominant in this area. (3)There are large proportion of archaic, relic and primitive plants in this area. This result shows clearly the ancient nature of this flora. (4)There are 12 genera Chinese endemic genera of seed plants and 11 species rare endangered plant. These analysis results showed that this region is an important composition of North China Region plant flora.

Key words: seed plants, flora, the middle-south area of east slope of Taihang Mountains
