摘要
本文通过对中国东北、华北、西北和西南地区菊科蒿属植物新鲜样品共128号38种4变种（分别隶属2亚属7组）的茎、叶横切面作比较、分析，叶的类型为等面叶和异面叶，前者多为原始类群且多出现在高海拔与高纬度的长日照干旱地区，后者多为进化或较进化类群且多出现在低海拔与低纬度的短日照湿润地区.茎的结构各组之间差异不大，大多数种类髓发达.其研究结果在分类学和生态学上具有一定的意义.
The structure of leaf and stem from 38 species and 4 variations, which belong to 7 sections and 2 subgenera of Artemisia L. in China, has been examined with LM. There are two types, the isoloteral leaf and the bifacial leaf, in represents of species. The species which frequently ocCured in high altitude and latitude area to long - day dry one, usually be the isolateral type and the ancestoral group. The species which mostly found in low altitude and latitude area to short - day humid one, are advanced or more advanced group and the bifacial type. There is little difference in stem structure in Artemisia L.. The results of the study are of the systematic and ecological significance in the genus.
