In this article, we tracked down the collecting locality of the holotype specimen of Allium rhabdotum Stearn (Amaryllidaceae), and proved that its type locality lies within Cona County, Xizang Autonomous Region, Peoples Republic of China, rather than within the Kingdom of Bhutan; thus A. rhabdotum has never been endemic to Bhutan. Recent collections of A. rhabdotum in Lhünzê County, Xizang were also reported here, providing new information to the species distribution. We named the plant in Chinese and supplied its morphology and habitat description, as well as discussed its diagnostic characters, phylogenetic position, exploitability, conservation status, and potential distribution.
