摘　　要：本文对东北产萝科三属五种植物的营养器官进行了比较解剖学研究，其初步结论：①徐长卿和白前属具须根系的种类更为接近。认为Ｋｉｔａｇａｗａ等把徐长卿归为白前属更合适。②白前属三种皆具须根系，无明显的区别，但与其它属在根系区别明显。③杠柳属的杠柳在解剖学上看不出和白前属及萝属有较本质的区别。④杠柳属和白前属相差较大，而萝属介于前两属之间。The comparative anatomy of vegetateine organ of three genera of Asclepiadaceal inNortheast was studied in this paper. The results as fOllows f T Xu Chang -qing ismore like the species with fibrus roots in genus Cynanchum . So Kitagawa changed thename of Xu Chang - qing as Cynanchum paniculatum is agreed. ② Three species of genus Cynanchum are all with fibrus roots. The root systems of them have no differentobviously, but have different obviously with oiller genera. ③There arc no naturely differences the Periploca Sepium Bunge. and other two genera . ④ There are many differences between Periploca L. and Cynanchum L., but Metaplexis R, Br. scem to be theintermediate for between tow genera.
