Allium cyathophorum is a Chinese (杯花韭, bei hua jiu) species of the Allium (onion) genus in the Amaryllidaceae (amaryllis) family.[1] It grows at elevations of 2700–4600 m.[2]
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.[2][3]
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:[2]
- Allium cyathophorum var. cyathophorum (Syn. Allium venustum C.H.Wright)[4] --- tepals blunt-tipped - Qinghai, Sichuan, Tibet, Yunnan
- Allium cyathophorum var. farreri (Stearn) Stearn (Syn. Allium farreri Stearn)[5][6][7] -- 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.
