Sinosenecio jiangxiensis Y. Liu & Q. E. Yang, a new species from Jiangxi, China, is described and illustrated and its chromosome number (2n=48) is reported. The karyotype is formulated as 2n=42m+4sm+2st (2sat). Sinosenecio jiangxiensis is similar to S. guangxiensis C. Jeffrey & Y. L. Chen and S. latouchei (J. F. Jeffrey) B. Nord. in leaf shape, abaxial leaf surface indumentum and achene pubescence, but differs in its smaller stature, smaller basal leaves, stem leafless or bearing only 1 bract-like leaf near the middle and thus more typically scapiform, and usually solitary capitula. Analysis of ITS sequences further confirmed the distinction of S. jiangxiensis and also revealed that S. jiangxiensis is closely related to S. guangxiensis, S. jiuhuashanicus C. Jeffrey & Y. L. Chen, S. latouchei, S. saxatilis Y. L. Chen, and S. wuyiensis Y. L. Chen, with S. jiuhuashanicus, S. latouchei and S. wuyiensis being the closest relatives. A detailed comparison of these species is made, and a key to them is provided.
