Allium vineale
''Allium vineale'' (Wild Garlic, Crow Garlic or stag's garlic) is a perennial, bulb-forming species ''wild onions'', native to Europe, northwestern Africa and the Middle East.〔(Kew World Checklist of Selected Plant Families )〕 The species was introduced in Australia and North America, where it has become a noxious weed.

==Description==
All parts of the plant have a strong garlic odour. The underground bulb is 1-2 cm diameter, with a fibrous outer layer. The main stem grows to 30-120 cm tall, bearing 2-4 leaves and an apical inflorescence 2-5 cm diameter comprising a number of small bulbils and none to a few flowers, subtended by a basal bract. The leaves are slender hollow tubes, 15-60 cm long and 2-4 mm thick, waxy texture, with a groove along the side of the leaf facing the stem. The inflorescence is a tight umbel surrounded by a membranous bract in bud which withers when the flowers open. Each individual flower is stalked and has a pinkish-green perianth long. There are six tepals, six stamens and a pistil formed from three fused carpels. Mixed with the flowers are several of yellowish-brown bulbils. The fruit is a capsule but the seeds seldom set and propagation usually takes place when the bulbils are knocked off and grow into new plants.〔(【引用サイトリンク】title=Wild garlic: ''Allium vineale'' )〕 Plants with no flowers, only bulbils, are sometimes distinguished as the variety ''Allium vineale'' var. ''compactum'', but this character is probably not taxonomically significant.
