Allium cyathophorum is a Chinese (Chinese: 杯花韭, bei hua jiu) species of flowering plant in the onion genus Allium of the family Amaryllidaceae.

[2] This bulbous herbaceous perennial has thick roots but thin, fibrous bulbs.

The leaves are flat, narrowly linear, usually shorter than the scapes.

The umbels are hemispheric (half spheres) with purple flowers.

Two infraspecific varieties are recognized:[2] William Stearn originally named Allium farreri in 1930 after Reginald Farrer, but in 1950 realised it was a variety of Allium cyathophorum, and so renamed it.
