Allium macrostemon (野蒜, ノビル), Chinese garlic, Japanese garlic or long-stamen onion,[5] is a species of wild onion widespread across much of East Asia.

It is known from many parts of China, as well as Japan (incl Ryukyu Islands), Korea, Mongolia, Tibet and Primorye.

It has been collected from elevations ranging from sea level to 3000 m.[6][7][8][9][10] Allium macrostemon produces one round bulb up to 2 cm in diameter.

Leaves are shorter than the scape, long and hollow, round or triangular in cross-section.

[6][11][12] Allium macrostemon is mentioned in Huangdi Neijing as one of the five consumable herbs (五菜) which included mallow (Malva verticillata) (葵), pea leaves (藿), Welsh onion (蔥) and garlic chives (韭).
