摘要
首次对河南省特有种及其区系地理和生态学特点进行了研究。结果显示:(1)河南特有植物有42种,隶属于37属,25科;(2)草本植物占64%,与河南维管植物区系的草本比例基本相同,其中多数为多年生草本,特有种绝大多数为陆生中生植物;(3)根据它们的分布特点,特有种可分为6个分布型,其中属于豫西山地分布型的种类最多,占总种数的60%;(4)这些特有种集中分布于豫西、豫南、豫西北山地和豫中黄河两岸四个地区,种类最多的是豫西山地。
The species endemic to Henan are presented and their floristic characteristics are analyzed in this paper. The results are as follows： （1）There are 42 endemic species in 37 genera of 25 families;（2）64% of them are herbs（mostly being Perennial）. This is similar to the flora of Henan. And majority of them belong to terrestrial mesophyte;（3）They can be divided into six distribution patterns, among which species belonging to West Mountains of Henan are the most abundant, making up 60% of the total ; （4）The endemic species are mostly concentrated in four areas： Mountain in West Henan, Mountain in South Henan, Mountain in Northwest Henan as well as around the Yellow River in Central Henan,more than half of them being in the Mountain in West Henan.
