Description:
Onion is a term used for many plants in the genus Allium. They are known by the common name "onion" but, used
without qualifiers, it usually refers to Allium cepa. Allium cepa is also known as the "garden onion" or "bulb" onion.
Above ground, the onion shows only a single vertical shoot; the bulb grows underground, and is used for energy storage,
leading to the possibility of confusion with a tuber, which it is not.
Allium cepa is known only in cultivation,but related wild species occur in Central Asia. The most closely related species
include Allium vavilovii (Popov & Vved.) and Allium asarense (R.M. Fritsch & Matin) from Iran. However, Zohary and
Hopf warn that "there are doubts whether the vavilovii collections tested represent genuine wild material or only feral
derivatives of the crop.
