%X <p>The morphological description of <i>Aster longipetiolatus</i> 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 <i>A. longipetiolatus</i> 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 <i>A</i>. <i>longipetiolatus</i>. 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.</p>
