Description

Allium cyathophorum has thick roots but thin, fibrous bulbs. Scapes are usually 2-angled, up to 15 cm tall. Leaves are flat, narrowly linear, usually shorter than the scapes. Umbels are hemispheric with purple flowers.

Taxonomy

A. cyathophorum is found in the third evolutionary line of the genus Allium. It is a member of 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 A. farreri in 1930 after Reginald Farrer, but in 1950 realised it was a variety of A. cyathophorum, and so renamed it.
