Two New Species of Allium L. from Sichuan

 This  paper  reports two new species of Allium  L. from Sichuan, A. xiangchengense J. M. Xu and A.guanxianense J. M. Xu. The former is related to A. hookeri Thwaites, but differs from it by its lanceolate to linear-lanceolate leaves with evidently contracted base and filaments longer than the tepals, while the latter is related to A.chienchuanense J. M. Xu, but differs from it by its termi- nal scape, filaments shorter than the tepals and ovary with solitary ovule in eachlocule.
