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) – 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.
