A small white flower on a straight branchy stem attracts the attention of many, as passers-by confuse it with a medicinal plant, called chamomile. But it is worth bending lower, as there is a noticeable difference - the flower has no smell at all. The thing is that this chamomile is odorless, that is a weed common in the fields and gardens.

The family unites a large group of herbaceous plants with a complex flower representing a basket of small flowers. They can be tubular or reed, and some have a mixed basket. Chamomile is odorless in the basket and combines tubular and reed flowers, which fully corresponds to the declared family.

The leaves of her are pinnately dissected, consisting of filamentary lobes. Inflorescence type is a basket of round shape. It is located at the ends of stalks or branches. Leaflets covering the basket have a blunt elongated shape, the flower-head slightly conical. The marginal flowers of the white-colored tongue-shaped basket. They are longer than the covering petals. The middle part of the inflorescence consists of yellow tubular flowers.

What does a plant look like?

Chamomile chamomile has several flattened fruits-achenes of dark brown color. A distinctive feature of the fetus is a short leathery crest. The length of each achene is no more than 2 mm, width - 1 mm. Weight is also quite small, it can vary from 0.2 to 0.5 mg.

The shape of the fetus is reflected in the name of the plant genus. Precisely because the seed has three distinct facets, the chamomile is odorless to the genus of the three-ribbed.

Where is the plant found?

Chamomile odorless - a weed that clogs corn fields and fodder meadows. She meets at dachas and kitchen gardens, on roadsides and around garbage dumps. Often weeds are found along the banks of water bodies. The plant is particularly at risk for winter rye plantation near forest plantations.
