The morphological description of Aster longipetiolatus C.C.Chang was inadequate in the original literature when compared with the specimen which we collected from its type locality, and there was a lack of cytological reports. The detailed morphological and cytological description of A. longipetiolatus were carried out, and the new evidences of plant taxonomical revision would be provided. The results showed that: ①There were some newly-discovered characteristics for A. longipetiolatus. For example, the receptacle was convex, phyllaries 3- or 4-seriate, ray floret staminodes, lamina pilosulose and achenes 5-ribbed; ②Its cytology evidence revealed that the chromosome number was 2n=18 and the karyotype formulae was 2n=2x=16m+2sm, belonged to the type 1A.

Key words: Asteraceae, morphology, staminode, karyotype analysis
