摘　　要：本文对作者本人在1983年《中国植物志》第76卷第一分册121页上针对川甘亚菊处理过宽的问题,重新作出了订正。本文确认川甘亚菊、灰叶亚菊、深裂亚菊及下白亚菊分别为不同的种,并作出了这四个种的分种检索表。In 1983, in Flora Reipublicae Popularis Sinicae 76 (1) Ajania potaninii (Krasch. ) Poljak. was treated broadly by the present author. At that time. Chrysanthemum potaninii (Krasch. ) Hand. -Mazz. var. amphiseriaceum Hand. -Mazz. , Chrysanthemum trun-catum Hand. -Mazz. and Ajania hypoleuca Ling in shed were treated as synonyms of Ajania potaninii (Krasch. ) Poljak. Evidently, the treatment of the three taxa was not suitable. It seems neccessary to make further revision in the present paper. Abovementioned three names treated as synonyms should be regarded as three different species of Ajania. However, these three species are closely related to Ajania potaninii (Krasch. ) Poljak. They are keying as follows; 1. Leaves undivided. 2. Leaves discolour, green, glabrous above, cinereous-white, densely white-tomentose beneath ............................................ 1. Ajania potaninii (Krasch.) Poljak. 2. Leaves concolour on both sides, cinereous-white, densely white-tomentose ......... ................................................ 2. Ajania amphiseriacea (Hand.-Mazz. ) Shih 1. Leaves pinnatipartite or pinnatisect. 3. Leaves pinnatipartite, discolour, green, glabrous above, cinereous-white, densely white-tomentose beneath ....................................... 3. Ajania hypoleuca Ling 3. Leaves pinnatisect, concolour on both sides, cinereous-white, densely white-tomen-tosa ............................................. 4. Ajania truncata (Hand.-Mazz. ) Ling
