Allium cyathophorum is a Chinese (杯花韭, bei hua jiu) species of flowering plant in the onion genus Allium of the family Amaryllidaceae.[1] It grows at elevations from 2700 metres up to 4600 metres.[2]
Description
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.[2][3]
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:[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 Allium farreri in 1930 after Reginald Farrer, but in 1950 realised it was a variety of Allium cyathophorum, and so renamed it.
