Description
This bulbous herbaceous perennial has thick roots but thin, fibrous bulbs. The scapes are usually 2-angled, up to {{convert|15|cm|in|abbr=on}} tall. The leaves are flat, narrowly linear, usually shorter than the scapes. The umbels are hemispheric (half spheres) with purple flowers.Bureau, Louis Édouard, & Franchet, Adrien René. 1891.

=Varieties=
Two infraspecific varieties are recognized:
- Allium cyathophorum var. cyathophorum (Syn. Allium venustum C.H.Wright) – tepals blunt-tipped – Qinghai, Sichuan, Tibet, Yunnan
- Allium cyathophorum var. farreri (Stearn) Stearn (Syn. Allium farreri Stearn){{Sfn|Stearn|1930}}{{sfn|Stearn|1955a}} – tepals pointed at the tips – Gansu, Sichuan
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.
