Abstract:

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 fol-

lows:

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-

rosa ............................................. 4. Ajania truncata (Hand.-Mazz. ) Ling

Key words: Ajania, A. hypoleuca Ling, A. truncata (Hand.-Mazz.) Ling, A. amphiseriacea (Hand.-Mazz.) Shih
