They are as follows: 1) Plant species are rich, with 2953 wild species in 896 genera of 152 families, putting Henan in front rank in the northern areas of China. 2) Its origin is from far ancientry, and there exist many primitive families and genera as well as many relic species. 3) The character of transition is very conspicuous with complex and varied geographical elements, but the temperate type being the dominant. There are 15 types and 18 variants of distribution types at the genera level, the typical Temperate, Tropic and East Asia elements respectively make up 47.9%, 29.5% and 14.5%. 4) It is rich in species endemic to China, with 1514 species, ranking first in the northern areas in China. 5) The floristic spatial differentia is obvious. The southeastern Henan belongs to East China plant region, the southwestern to Central China, the northern and the central to North China.展开更多
