This bulbous herbaceous perennial has thick roots but thin, fibrous bulbs. The scapes are usually 2-angled, up to 15 cm (5.9 in) tall. The leaves are flat, narrowly linear, usually shorter than the scapes. The umbels are hemispheric (half spheres) with purple flowers.
Taxonomy
Allium cyathophorum is found in the third evolutionary line of the genus Allium. It is a member of the subgenus Cyathophora and is the type species for that subgenus.
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.
