Abstract

In this paper, a new species of the genus Rosa from China, Rosa tomurensis L. Luo, C. Yu & Q. X. Zhang, is described and illustrated. In the past, R. tomurensis was considered as a variety of Rosa laxa. After years of field investigation, introduction and cultivation, comparison and measurement of plant specimens, our research team found that R. tomurensis has stable characters, and its morphological characteristics, sporopollen, chromosome karyotype and genome are obviously different from R. laxa. Therefore, it is confirmed that R. tomurensis is an independent species in Rosa.
